Second Global Surveyors Day : Chain to Drone Survey

Second Global Surveyors Day : Chain to Drone Survey

Buddhi Narayan Shrestha

Founder President, Nepal Institution of Chartered Surveyors

Nepal Institution of Chartered Surveyors (NICS) organized the Second Global Surveyors Day in Survey Department Geodetic Hall on 21st March 2019; with the collaboration of Nepal Geomatics Engineering Society (NGES), Nepal Remote Sensing & Photogrammetric Society (NRSPS), and Nepal Surveyors Association (NSA); and supported by Survey Department (SD) and UN Global Geospatial Information Management (UNGGIM). The program was organized into two parts: first the inauguration function and the second session was the panel discussion.

A. First session: Inauguration

The session was chaired by Punya Prasad Oli, President of NICS. Hon’ble Minister for Land Management Ms. Padma Kumari Aryal was the chief guest. National Planning Commission (NPC) Hon’ble Member Dr. Sushil Bhatta was the special guest and Secretary to Ministry of Land Management Gopi Nath Mainali was the guest of the program.

During the inaugural session, Minister Ms. Aryal mentioned that survey, mapping and geo-informatics organizations must help to the government and the State to establish accurate data and prepare exact maps in connection to establish effective land management and administration of the nation. Professionalism should be maintained by the Surveyors of all disciplines. Modern technology should be imported to carry on the smart land administration. The ministry is to act on the e-governance of land. We need contribution from the land related organizations and associations. In this aspect I wish all the best for the successful and fruitful objectives of the Second Global Surveyors Day.

NPC Member Hon’ble Engineer Dr. Sushil Bhatta delivered a Key Note Speech that for the planning and execution of the economic development projects of the nation, Surveyors role is important for the preparation of necessary maps and field data. For the hydro-electric generation project, first and foremost, it needs accurate topographical maps with detail surveying to make a plan to locate the main power house, alignment of the water channel and formulation of transmission line. Surveyors have a hardship life in the field from the beginning to the end of the project. In this perspective, Surveyors must maintain credibility, code of conduct and ethics. He expressed for the success of the global surveyors day programme.

From the chair, NICS President Punya Prasad Oli expressed that after the 2015 earthquake in Nepal, some geodetic control points might have been shaky. It should be revitalized. We, the Surveyors must be cautious to maintain our profession and professionalism adopting the ethics and code of conduct propounded by the International Federation of Surveyors (FIG). Border issues of Kalapani and Susta area conflicts should be resolved amicably with our neighbouring country. It needs the professional skill, know-how and field experiences.

President of the NGES Er. Sharad Chandra Mainali thanked all for sparing their time to observe second global surveyors day. He further said, it’s a matter of pride to celebrate the Day in Nepal to enhance our survey profession and identity of Surveyors. We have to be capable to adopt new techniques and technologies to maintain Surveyors identity.

6. Questions/Theme of discussion for each panelist:

In the beginning of panel discussion, Coordinator Mr. Janak Raj Joshi made an opening remark and introduced the panelists, and mentioned the moderation processes.

6.1 First Generation (1960 to 1975): Chain Survey to Tacheometry

At first, moderator Mr. Joshi made a question to Mr. Buddhi Narayan Shrestha in the first and second round discussions: You are one of the pioneering the profession and a contributor to laying foundation of surveying in Nepal. Your generation started from Chain, continued with PT, and come up with a result of cadastral mapping system and geodetic control network, trigonometric surveying systems. What Challenges did you face to establish and strengthen the profession, how did you do all these things from the beginning?

Responding to moderator’s desire, Mr. Shrestha mentioned, representing the period 1960 to 1975 from Chain to Tacheometry Survey:

  1. First generation was the take-off stage of Surveying & Geomatics in Nepal. This was from traditional to technical developing stage.
  2. Land registration system from conveyancing to deed.    
  3. Equipment used: from chain to tape, plane table (with sight rule), microptic telescope alidade with stadia rod, Theodolite and then EDM (tacheometry).

  3. In-house Training: Basic Surveyor to Senior Surveyor and Special Courses under the assistance of Colombo Plan.
  4. Abroad: Land Surveying Course to 500 Survey Engineering Course.
  5. Publication of Technical Circulars Survey Directory 1967-72, Triangulation Instruction Book-1975.
  6. Equipment repair and maintenance workshop was established with the assistance of Japanese JOCV Volunteers with Nepal counterpart.


  1. This generation was able to import foreign technology, as an opportunity to develop surveying activities in Nepal.
  2. Educated persons started to enter into Survey department services.
  3. UNDP experts started to reform survey organization.
  4. Initiated technical procedures on the measurement of land and establishment of land records.
  5. Measurement of land and computation of area was carried on from local to metric unit.
  6. Nepali Surveyors obtained opportunities to attend the surveying education abroad.
  7. Organization was expanded and established divisions and branches.
  8. Surveyors started to write books on Surveying, e.g. first book entitled ‘ Surveying’ was written by Director Netra Bahadur Thapa in 1961.
  9. Survey Department started to participate in UN Cartographic Conferences.

6.2 Second Generation (1975 to 1990): Tacheometry to Photogrammetry

Moderator Mr. Joshi put a question to Mr. Babu Ram Acharya in both the round discussions: You took the profession further and establish it in the international level. You also initiated technological development such as GPS and Total stations. Also GIS and Remote sensing system was introduced in surveying and mapping in Nepal, Topographic base maps, completion of cadastral mapping, NTDB and NSDI are the initiatives that has been contributed by your generation. How was the change managed? How did you convince the politicians and policy makers that these changes in the surveying and mapping are inevitable? What are those things that you want to carry further but couldn’t make it happened?

Mr. Acharya, as the second generation panelist responded to Mr. Joshi: you are correct that you have mentioned the activities of the development of surveying, mapping and geomatics from 1975 to 1990.

Changed management

  1. Doppler survey was carried on with the establishment of fundamental station at Nagarkot Hill with the help of Czech Republic.
  2. Nagarkot fundamental station was expanded by running 24 hours GPS tracking.
  3. Traditional Survey Goswaras (Groups) were dissolved and the manpower was transferred to district survey office, which were more concerned for the day to day transaction of land of general people in relation to land administration.  
  4. The identity of the Survey Department was expanded to the international level with the assistance of the foreigner donour agencies.
  5. Survey Department obtained the Affiliate Membership of FIG.
  6. Asian Conference on Remote Sensing was held in Kathmandu for the first time in Nepal.
  7. Software and its sharing system was developed for the national geographic information system as per the geographic location and situation of Nepal.

Convince the politicians and policy makers

  • I could not convince too much to the politicians that surveying activities are important for the development of the nation.  Rather they were interested to invest more in drinking water, road construction and hydro-electric generation projects.
  • I insisted them that those projects, at first, need accurate maps and data for the planning and implementation/execution of the project.   


  1. Nepali Surveyors had obtained academic qualification and training from UK, USA, India, Netherlands, and Czech Republic etc. But the education they had obtained was not in the integrated form and it was not utilized so much in the Nepali soil. There were variations to accredit for the promotions on the higher posts, enunciated by the Tribhuvan University. Some of the Surveyors had the basic intermediate qualifications in two or more disciplines and they wanted to have graduation standards for the career promotion. In some cases, it was not materialized and they were rather frustrated. 
  2. However, it was made accountable to the concerning officers in relation to their basic and higher education and training. For example, base mapping work was assigned to those who had knowledge on photogrammetry and remote sensing.
  3. National Geographic Integrated Infrastructure Programme was given to those who had skill on information technology. 
  4. The work of head of the Survey Department was a little bit difficult to make understandable to the Secretary and Hon’ble Minister of the Ministry of Land Reform.

Wanted to carry further but couldn’t make it happened

  1. Whatever and however there should have been the development of technological improvement, it was not enough. It may be due to the mixed feeling of the manpower.
  2. It was not so much done on the aspect of the data security due to the lack of government national policy at large.
  3. I wanted to update various types of land utilization maps and data prepared during 1980s by Land Resources Mapping Project, assisted by Canadian International Development Agency. But these were not materialized due to its analog form. 
  4. Regarding the Cadastre, my intention was to adopt the fixed boundary principle with legal adjudication. But it was not possible without amending existing Land (Survey & Measurement) Act and Regulation. It was up to the matter of the Council of Ministers. I tried to push forward from the department, but it was not enough without the spirit of the honourable Minister.   

6.3 Third Generation (1990 to 2005): Photogrammetry to Lidar Survey

The moderator asked to Mr. Ganesh Prasad Bhatta on both the sessions: You are the person with hope; you are in the driving (hot) seat; where are you taking this profession? What do you think about the current status of the profession? What did you get from your earlier generation and what do you want to hand over to coming generation?

In response to moderator’s query, Mr. Bhatta mentioned as followings:

Taking this profession forward

  • The initial work started by the former generation will be carried out in continuation, but in a developed form with modern technology.
  • I am concentrated to raise the standard of the surveying, mapping and geospatial science profession of our country in a higher degree by adopting latest innovative techniques.

Got from earlier generation

  • I must appreciate previous generations that they endeavored to carry on surveying activities whatever it was prevalent and feasible at that time.
  • That was the basis to come into up to this generation.
  • They have established the technical foundation whatever it was available during that era.
  • We have to march forward on the background of the lessons, the previous generations had experienced.

     Current status of the profession

  1. The data established by the previous generation are not in digital form, so that it is difficult to update. The then technology has changed in the current status.
  2. It needs skilled manpower for the adoption of modern technology.
  3. In Nepal, angle of vision to look at the Surveyors by the general people is somehow negative in some extent.  It is imperative to improve, especially in the field of cadastral work, which is concerned with the civic society.
  4. This is a kind of challenge, how could we transform it into positive aspect.
  5. Recently, Nepal has been divided into 7 Provincial States with 753 local bodies, as per the new constitution of Nepal-2015.
  6. This is a kind of challenge, how could we provide 753 Geomatics Survey Engineers in each local body. We don’t have sufficient manpower to deploy up to the grass root tier of local government.
  7. To fulfil this necessity, it needs to produce skilled manpower, as the skilled manpower cannot be produced overnight. It should be invited to young generation to join this profession.
  8. The other challenge is the collaboration of government and private sector in the field of mapping. All the activities could not be done by the government sector. So private sector must be encouraged as the subordinate of government sector.
  9. Survey Department is going to measure the height of Mount Everest (Sagarmatha), the national heritage of Nepal.
  10. We shall use the modern equipment GNNS and GPR which will be operated by the Surveyors on the top of Everest to obtain satellite data. Data processing will be done by the qualified Survey professionals adopting the most recent technology, involving at least representatives from Survey of India and Chinese Bureau of Surveying & Mapping, so that our measurement will be recognized by the researchers and scientists of the world.

Hand over to coming generation

  1. Practical programmes have been formulated, as the Lidar Survey has been started for the future generation.
  2. Progress is going on for the instalment of new working software.
  3. Consolidation of geodetic control points have been started after the 2015 earthquake.
  4. Environment of transformation of newly developed technology in some parts of the world has been followed by our organization.
  5. Useful works, for example, the updating of topographic mapping have been advanced for the future generation.
  6. Need of the nation in the sector of spatial science has been identified to make the work of the future generation smooth.

6.4 Fourth Generation (2005 to 2019): Lidar Survey to Drone Survey On both the sessions, Moderator gave clues to Ms. Bhuvan Ranjit: You are the future of this profession; when you enter in this profession, what were your expectations and wishes? Did you find the profession same as you dreamt about? What do you now expect from the current leaders? And what will be the things that you wish to change when you will be in leadership?

Ms. Bhuvan Ranjit was quick to highlight on the clue given by the moderator on:

My expectations and wishes

  1. Yes, I am the future of this profession. I know the dream of the future generation and what should we do for the betterment of this profession and our nation as well.
  2. I wish I could be the bridge between previous generation and forthcoming generation on surveying and spatial science.  
  3. We have to prepare qualified Young Surveyors who could play an important role to show their technical skill for the development of professionalism in Nepal.
  4. There must have effective research and development (R & D) unit in the department to find out the feasible modern technology and working procedure suitable to our nation.

Expect from the current leaders

  • I hope environment of extension of Lidar activities will be created by the current leadership of the department of Survey.
  • I expect Satellite Receiving Ground Station will be established in our country soon, so that my generation could use and handle the data received by our own for the professional development.
  • Leadership should be shifted to the new generation who have sufficient academic knowledge of new technique, technology and field experience.

I wish to change when I will be in leadership

  1. I shall try to maintain democratization of national mapping organization. In my opinion new thinking should be channelized with an appropriate sense.  
  2. This will be our main responsibility that professional challenge must be faced by our generation.
  3. Spatial data must be fully prepared by the 4th generation and we will develop software, suitable as per the need of our organization. This will surely be an innovative work.
  4. There should not have financial constraint, as it needs for the development of professionalism.
  5. Youth will be employed as an open source to make the software ourselves.
  6. The most important thing that we must go to digital system in full swing.
  7. We have to make capable to our professionals to fly the Drone and get photographs and data to update the basic topographic maps and spatial data, as the equipment Drone has been used in Nepal by international agencies to find out the damage caused by 2015 earthquake. It needs further academic education and technical training to catch the ‘Drone Survey.’

6.5 Fifth Generation (From 2020 onward): Drone Survey to Mini-Satellite

Moderator Mr. Joshi produced a substantive matter on both the sessions to Mr. Uttam Pudasaini: You chose a different way or better to say you paved your own way. What was the thing that motivated you to initiate your own entrepreneurship? How do you see the challenges and opportunities in the private sector in this profession? What do you expect from government that would support the development of private sector in this profession? What do you suggest for an enhanced cooperation between public, private and academic sector?

Mr. Uttam Pudasaini, who has not yet started his career in the Government sector expressed his feeling and experiences gained in the private sector on the following sub-heading:

Motivation to initiate my own entrepreneurship

  • I am inspired to walk with my feet in this profession, as I visualized the importance of surveying and mapping that was most needed for the planning of various economic projects in our country.
  • It was heard the name of foreign Universities, but the name of our native Universities were on shade. I obtained the basic academic qualification from our non-government University. So I thought why not to start my professional work in non-government sector with my own entrepreneurship.

Challenges and opportunities in the private sector in this profession

  1. In the beginning, it was very hard to obtain the work, as a private professional.
  2. In the meantime I started online GIS.
  3. There were many challenges for the technical development, as this work would have not been done by private sector previously. I started and moved on slowly but tirelessly. I produced my digital work and floated on web surfer.  And it was believed by the clients that private sector also can perform the job as per standard.
  4. I dare to say that database creation is purely a technical job. It needs skillful knowledge and dedication.
  5. Nepal is entering into digital age. We have to follow modern technology in the field of surveying and spatial science, utilizing best practices.

Expectation from government to support private sector

  1. The government must let the new generation to make scientific experimentation on our profession.
  2. Government must realize that private sector could generate data more accurate than the government agencies in some particular field.
  3. Public and private sector Survey professionals must march forward hand to hand for the overall development of Nepal.
  4. Congenial rules and regulations should be formulated to groom the private sector Surveyors.

Suggestions for cooperation between public, private and academic sector

  1. To promote private sector, the government must provide license to the capable personnel and professional organizations, defining the working procedure and the national norms, standards and specifications set by the central agency of the government.
  2. Government must stop to those capable personnel to flee foreign countries, who are dedicated to work within the territory of Nepal.
  3. Role of technical leadership must be taken and maintained by the government Survey Department.
  4. Database should be established by public-private modality.
  5. There should have data sharing system with a reasonable modality.
  6. Government sector must provide encouragement to expand and maintain professional status of the private sector professionals.
  7. Nepal has launched recently its own Mini-Satellite ‘NEPALISAT-1’ with the help of America (Virginia) on the orbit, constructed by the Nepalese working in Japanese academic field.
  8. The photographs and data received from NepaliSat-1 should be used also by the private sector professionals, paying reasonable and moderate fee.

After the completion of second round of the panel discussions, there were queries, questions, suggestions and highlights from the audiences to the selected panelists. The panelists had answered the queries raised from the floor, remaining at proximity and vicinity of their presentations. Priority had been given to the queries of young surveyors and professionals.

At last, moderator Mr. Joshi spoke, in short, on the usefulness of the panel discussion. He expressed his opinion that such interactions will be very useful, fruitful and meaningful for the development of professionals. It has been a historic lessons, especially for the new generation. At the end Mr. Joshi thanked all the panelists and audiences for their co-operation that made easy to conduct the session, so that the whole period of panel discussions went smooth.

7. Closing Program

After the panel discussion session, closing program was conducted. The programme was chaired by the Secretary, Ministry of Land Management Mr. Gopi Nath Mainali. He congratulated the NICS, its collaborators and supporting organizations to celebrate the global Surveyors Day also in Nepal, with a lively panel discussion. He narrated that the new generation must be capable not only to carry on the activities performed by the bygone generation, but also expand their thinking with high performances. New generation always must talk in positive sense and expand their capabilities without individualism. They should love and honour their organizations and institutions. They should not have their mentality to gain a lot of facilities within a short span of time. They must have patience that the time surely will come for them as well. The argument of the young surveyors should be based on logic, skill, facts and figures. Professionals must respect each other in all spheres.

In the concluding item, Survey Department Director General Mr. Ganesh Prasad Bhatta and President of Nepal Remote Sensing & Photogrammetric Society Mr. Rabin Kaji Sharma expressed happiness that Second Global Surveyors Day in Nepal is observed most successfully.  The panel discussion was most interesting, as it was educative and informative for all the Survey professionals. The new generation must go forward adopting the technique and technology as emerged in the global aspect, enunciated by the FIG.

At the end of the closing program, Token of Appreciation was presented to the panelists and guests of honour by Surveyor/Er Sharad Chandra Mainali, on behalf of the organizing committee. Nepalese style delicious dinner was served to all the participants, panelists and guests to enhance the fellowship among Survey professionals.

2nd Global Surveyors Day

2nd Global Surveyors Day

Buddhi Narayan Shrestha
Former Survey Director General and
Border Researcher

21st March is the Global Surveyors Day (GSD) that will be celebrated in various countries of the world every year. The Day recognises the work of surveying, mapping and geospatial professionals. This is a worldwide event initiated by the International Federation of Surveyors (FIG) based in Denmark, the Council of European Geodetic Surveyors (CLGE), and the National Society of Professional Surveyors (NSPS) in the USA. FIG has initiated to celebrate the Day by the country association around the world.

Surveying, mapping and geospatial information are necessary for the planning, designing, estimation and execution of development projects; such as generation of hydro-electric projects, infrastructure development including construction of roads and railways, development of urban cities and rural towns and settlements. It is to produce accurate, exact and up-to-date maps and related data for the successful implementation of the project.

Land surveying is the measurement and mapping of our surrounding environment using mathematics, specialized technology and equipment. Surveyors measure just about anything on the land, in the sky or on the ocean bed. They even measure polar ice-caps

FIG has determined the norms and standard, specification and modality of surveying, mapping and geo-informatics system (GIS) of the world. FIG is is an UN-accredited organisation which represents the interests of surveyors throughout the world.

Surveyors play an integral role in land development, from the planning and design of land subdivisions through to the final construction of roads, utilities and landscaping. Surveyors are the first people on any construction site, measuring and mapping the land. These primary measurements are then used by engineers to understand and make the most of the unique landscape when designing to plan structures accurately and safely, ensuring not only fit with the landscape but are able to be constructed. So the Global Surveyors Day has to be celebrated to encourage the surveyors of the world to produce exact and accurate maps and data for the development of the nation.

Who is a Surveyor ?

According to FIG, a surveyor is the professional person with academic qualifications and technical expertise to determine, measure and represent land, three-dimensional objects, point-fields and trajectories, to assemble and interpret land and geographically related information, to use that information for the planning and efficient administration of the land, the sea and any structures thereon, and to conduct research into the above practices and to develop them.


A Surveyor must exercise unbiased independent professional judgement; assume responsibility for all work carried out by their professional and non-professional staff, avoid any appearance of professional impropriety and make no fraudulent charges for services rendered.

Ethics and conduct of a Surveyor  

Surveyors must have integrity, independence, care and competence. Surveyors duty is to maintain confidentiality about the affairs of their current and former clients and employers unless required by law to make disclosures; avoid conflicts of interest; take environmental concerns into account in their operations and activities; recognise the interests of the public when providing services to their clients or employers; and conduct their work to the best of their ability, giving due consideration to the rights of all parties

It is important that Nepali professional Surveyors must be affiliated with the FIG through their national association, Nepal Institution of Chartered Surveyors (NICS). In the meantime, Nepali Surveyors must obtain Survey License to make professional practices, as the medical Doctors get their licences from the Nepal Medical Council, also for those who work in government Hospitals.

Surveying, mapping system and GPS/GIS activities of Nepal should be more scientific as the norms and standards set by FIG.

Purpose to observe the Day

Main purpose to observe the Day is to reflect on the work that surveyors do. It is said that it is essential to know what impact of various kinds of surveyors can have all over the world. First edition of the Global Surveyors Day was specially marked at the World Bank Land and Poverty Conference in Washington DC, USA with representation of FIG, CLGE and NSPS and many other Surveyors and others from around the world who are in Washington DC.

It can be celebrated in many/different ways, and it is up to the national surveyors institutions to find their best way to celebrate the day. As part of the celebrations initiated by FIG, a Round Table should be placed to enable surveying professionals to discuss important topics in today’s world, followed by an evening reception as get-together.

FIG is the main umbrella of the Surveyors of the globe. It is a United Nations and World Bank recognized non-governmental organization of national member associations and other affiliated members from over 120 countries and Nepal is one of them. Nepal Institution of Chartered Surveyors (NICS) is its country member association. Government of Nepal Survey Department is the affiliate member and Land Management Training Center is the academic member of FIG from Nepal.

Reasons to observe the Day

Various organizations and agencies observe their World Day in their own way in one particular day of the year. For example, World Women Day will be celebrated on the 8th of March. In the same way, International Labour Day is observed on 1st of May every year. So as to mark the ‘Global Surveyors Day’ every year. In order to highlight the importance of a Surveyor, their job and the field work all over the world, the date 21st March has been chosen and named Global Surveyors Day. It is necessary to highlight that the tools as surveying, mapping and related GIS data and materials will be prepared and produced by the Surveyors, which are necessary for the planning and implementation of various economic development of the country.

Nepali context

Nepal has a huge potentiality of hydro-power generation. To plan and execute the hydro-power project, at first it needs accurate and exact maps and related data. So is the case for road construction project, urban/rural development programs, tourism development planning, so on and so forth in Nepal. The Nepali Surveyors generate these materials and the concerned Engineers use it as their essential tool. These activities of Surveyors should be highlighted and communicated through observing the Global Surveyors Day also in Nepal.

In connection to the activity of Surveyors, Ministry of Land Management has said that there are 30 million land parcels all over the country. The ministry has a plan to convert the registered land from manual data into digital form. The Minister Ms. Padma Kumari Aryal has said on February 25, 2019 that there are 131 survey and land management office across the country. Among them 54 offices have implemented the digital system. Rest of the offices will complete the digital system within two years period from now. Nepali Surveyors have to come forward to perform these tasks scientifically. 

In the meantime minister Aryal launched new official map of Nepal in Kathmandu on March 7, 2019. The map bears the boundaries of seven provinces with the names of head quarter three provinces–Gandaki, Karnali and Sudurpashchim, whereas other four provinces are numbered as 1, 2, 3 and 5. All these activities have been performed under the work of surveying and mapping, undertaken by the Surveyors.

Last year NICS celebrated the Day in association with the government Survey Department amidst a function in the Survey Department. Secretary of the Ministry of Agriculture, Land Management and Cooperatives Gopi Nath Mainali was the Chief Guest.

Last item

Global Surveyors Day will create awareness to the Surveyors of Nepal on their services to the society.  It will help to resolve the issues in connection to perform the surveying and mapping activities. It has to make well manage the works of Surveyors on the land, above the crust and underneath the surface of the world. Surveyors must be active. They must author their professional books and articles. Their profession should be respectful and take moral accountability.

The Surveyors have to be good and professionals. Role of the Surveyors is important for the nation. Private and public sector Surveyors must have good co-operation and co-ordination to prepare scientific maps and accurate data, needed for the implementation of various projects for the benefit of the people.

Surveyors must make their profession successful writing technical articles and books on the background of their knowledge and work experience to observe the global surveyors day to provide efficient land management services to the people and society.

सगरमाथाको नयाँ उचाइ टुंगो लाग्दै

 बुद्धिनारायण श्रेष्ठ

सरकारले सर्वोच्च शिखरको उचाइ मापन गर्न चैत २७ गते सगरमाथा आधार शिविरतर्फ प्राविधिक टोली पठाएको छ  । टोली सदस्यहरू एक महिनादेखि त्यस क्षेत्रको वातावरणसँग अनुकूल हुन ‘अक्लामेटाइजेसन’ गर्दै छन्  ।

उचाइ पचाउन आधार शिविरबाट ७,००१ मिटरमा रहेको तेस्रो क्याम्पसम्म ओहोर–दोहोर गर्दै, यन्त्र–उपकरण परीक्षण गर्दै छन् । उनीहरूले ५,०५० मिटरमा रहेको लोबुचेमा क्रस–ओरिजिन रिसोर्स सेयरिङ (सीओआरएस) नियन्त्रण विन्दु पनि स्थापना गरेका छन् ।

आफ्नो देशको सम्पत्तिका रूपमा रहेको विश्व सम्पदाको मापन तथा लेखाजोखा नेपाल आफैंले गर्दै छ । यसअघि कतिपय देशले सगरमाथाको उचाइ घटेको र कतिपय देशले बढेको भनेका छन् । सन् २०१५ को भूकम्पले सगरमाथाको उचाइ घटेको छ कि भन्ने शंकालु अध्येता पनि छन् । आफैंले मापन नगरेसम्म नेपालले पारम्परिक उचाइलाई नै मान्दै आएको छ । अबको मूल्यांकनपछि उचाइ घटबढ सम्बन्धी विवादको अन्त्य हुनेछ । तर मापन विश्वलाई चित्त बुझ्ने गरी आधुनिक विधिविज्ञान तथा प्रविधि अपनाई प्राविधिक तवरले गर्नुपर्छ । त्यसैले सगरमाथाको परिशुद्ध मापन चुनौतीपूर्ण छ । परिष्कृत उचाइ निर्धारण गरी संसारभरका सम्बन्धित क्षेत्रका वैज्ञानिक तथा अध्येतालाई सन्तुष्ट तुल्याउने यो अवसर पनि हो ।

२०११ मा सगरमाथाको सफल आरोहण गरिसकेका खिमलाल गौतमको नेतृत्वमा चार सर्भेयरले सगरमाथाको उचाइ मापन गर्दै छन्। मापन टोलीलाई चुचुरोसम्म पुर्‍याउन र फर्काउन पिक प्रमोसन प्रालिमार्फत चार सदस्यीय शेर्पा गाइडको नेतृत्व छिरिङ जाङ्बु शेर्पाले गरेका छन् । उनले दुईपटक सगरमाथा चुमिसकेका छन् । यो टोलीलाई प्रधानमन्त्री केपी ओलीले माला र टीका लगाई ‘एक सेन्टिमिटर पनि फरक नपर्ने गरी यथार्थ उचाइ नाप्नुहोला, तपाईंहरूले ल्याएको नाप नै सगरमाथाको आधिकारिक उचाइ हुनेछ’ भनी सफलताको कामना गर्दैे बिदाइ गरेका थिए ।

मापन कार्य
सगरमाथाको उचाइ मापन पूर्ण प्राविधिक कार्य हो । सगरमाथाको टुप्पोमा प्वाल पारी त्यहाँबाट फलामको मोटो डन्डी सीधै तल ठोक्दै सगरमाथाको पीँध अर्थात समुद्रको सतहसम्म पुर्‍याउँदा त्यो डन्डी कति मिटर लामो हुन्छ, त्यही नै सगरमाथाको उचाइ हो । बङ्गालको खाडीको पानीको सतह शून्य मिटरको उचाइ हो । त्यो शून्य मिटरको समतलन रेखालाई सगरमाथा टुप्पाको उचाइले बनाएको समतलन रेखासँग समानान्तर गरी सीधै तलतिर ९० डिग्रीको कोणमा त्यस्तो डन्डी ठोकिएको हुनुपर्छ । कोण दायाँ–बायाँ पारेर डन्डी ठोकिन पुग्यो भने त्यसले परिशुद्ध उचाइ जनाउन सक्दैन । यिनै कुरा सगरमाथा मापनका मुख्य विषय–वस्तु हुन् । वस्तुगत हिसाबले सगरमाथाको टुप्पोबाट डन्डी ठोकेर मापो लिन सकिँंदैन । बङ्गालको खाडीको पानीको सतहलाई शून्य मिटर उचाइ मानेर विभिन्न विधि तथा वैज्ञानिक तौरतरिका अवलम्बन गर्दै मैदानी भाग हुँदै त्रिकोणमितीय समतलन नापिन्छ । अनि सगरमाथाको टुप्पोसम्मको विन्दुमा यन्त्रद्वारा अवलोकन गरी उचाइ पत्ता लगाइन्छ ।

यसका लागि भारतको कोलकाताको समुद्र सतहदेखि नेपालको सिरहा जिल्लाको माडर अनि त्यहाँदेखि ओखलढुङ्गा–सोलु पिके डाँडासम्म १७० किलोमिटर त्रिकोणमितीय समतलन नापी गरिएको छ । तराईदेखि पहाडसम्म २३० स्थानको विन्दुमा जीएनएसएस (ग्लोबल नेभिगेसन स्याटेलाइट सिस्टम) प्रविधिबाट नापो लिइसकिएको छ । यीमध्ये १२ विन्दुसँगको सर्वेक्षणका आधारबाट सगरमाथाको चुचुरोमा एन्टेनायुक्त जीपीएस रिसिभर यन्त्रद्वारा ब्रह्माण्डमा तैरिरहेका स्याटेलाइटले दिएको डाटा क्याप्चर रेकर्ड गरिन्छ । यही डाटा रेकर्ड गर्न मापन टोली सगरमाथाको चुचुरोतर्फ लागेको हो । चुचुरोमा जीपीएस रिसिभरद्वारा रेकर्ड गर्न तथा चट्टानी भागदेखि चुचुराको हिउँको थुप्रोसम्मको उचाइ लिन ग्राउन्ड पेनिट्रेसन राडर (जीपीआर) का सहायताले मापन गरी संगणना गर्नु सफल आरोहण गर्नुजत्तिकै महत्त्वपूर्ण छ ।

जीपीएस प्रविधिद्वारा रेकर्ड गरिएको तथ्याङ्क र स्थापना गरिएका अन्य सर्वेक्षणका काँचाकोरा तथ्याङ्कलाई वैज्ञानिक तरिकाले प्रशोधन गरी परिष्कृत गर्नु निकै चुनौतीपूर्ण मानिन्छ । यस्ता चुनौतीमा मापनलाई परिशुद्ध गर्न डिफ्लेक्सन अफ भर्टिकल, जियोआइड, अब्सोलुट ग्राभिटेसनल एनिमोली, टेक्टोनिक मोसन, एटमस्फेरिक करेक्सन जस्ता प्रविधियुक्त क्यालकुलेसन (जोड–घटाउ) आवश्यक पर्ने हुन्छ । नेपालले निर्धारण गरेको नयाँ उचाइलाई विश्वका एक–दुई संस्था तथा व्यक्तिले चुनौती दिए भने तथ्य–तथ्यांक तथा विधि उल्लेख गर्दै सामना गर्नुपर्ने हुन्छ । २०७२ को भूकम्पले उचाइ खलबलाएको रहेछ/रहेनछ, अनि हिमचुलीको टुप्पोमा थुप्रेको हिउँको उचाइ समेतको मापन हो कि त्यसभित्रको चट्टानको भन्ने विषयलाई पनि चुनौती मान्नुपर्छ । अमेरिका भन्छ— सगरमाथाको उचाइ २ मिटर बढेको छ । चीन ठोकुवा गर्छ— ४ मिटर घटेको छ । अहिले मापन गर्दा बढेको देखिए वा घटेको पाइए, के कारणले यस्तो भएको हो भन्ने प्राविधिक तथ्य उजागर गर्नु पनि चुनौती हो ।

तथ्यांक प्रशोधन
प्राप्त विभिन्न तथ्यांक प्रशोधन गरी परिष्कृत तुल्याउन उच्चस्तरीय समन्वय समिति गठन गर्नु सान्दर्भिक हुन्छ । त्यसमा प्राविधिक उपसमिति तथा टोलीहरूले कार्य गर्ने संयन्त्र बनाउनुपर्छ । उपसमितिमा सर्भेयर, डिजिटल एस्ट्रोनमर, जियोफिजिसिस्ट, हाइड्रोलजिस्ट, जियोम्याटिस्ट, डाटा प्रोसेसर, जियोसाइन्टिस्ट जस्ता विषयविज्ञ रहनुपर्छ । तथ्यांक प्रशोधनका क्रममा चीन र भारतलाई पनि सहभागी गराउनु समय–सापेक्ष हुन्छ । किनभने सगरमाथा नेपाल–चीन सीमामा छ, अर्कातिर भारतले पिक–१५ (सगरमाथा) विश्वको सबैभन्दा अग्लो हिमचुली हो भनी पत्ता लगाएको हो । तथ्यांक प्रशोधन गर्दा तापक्रम, गुरुत्वाकर्षण, मौसमी शुष्कता आर्द्रता, हावाको चाप परिष्कृत गरिनुपर्छ । उच्चस्तरीय समन्वय समितिले गर्ने कामको तथ्यता/सत्यता बढाउन अमेरिकाको नेसनल जियोग्राफिक/बोस्टन म्युजियम अफ साइन्स, युएन कार्टोग्राफिक डिभिजन, इन्टरनेसनल एसोसियसन अफ जियोडेसी, इन्टरनेसनल फेडरेसन अफ क्लाइम्बिङ एन्ड माउन्टेनियरिङ, युनाभकोलाई समितिको आमन्त्रित सदस्यका हैसियतमा संलग्न गराउँदा परिणाम घोषणाको वजन बढ्छ ।

सगरमाथा मापनकार्य चुनौती र जोखिमपूर्ण भए पनि यसमा अवसरसमेत जोडिएको छ । नेपालका सर्भेयर प्राविधिक तथा वैज्ञानिकहरू मापनकार्यमा निपुण रहेछन् भनी विश्वसमक्ष कौशल देखाउने मौका हो यो । नेपालमा रहेका हिमालयको अध्ययन–अनुसन्धान गर्ने तथा हिमाली भूकम्पको जोखिमको लेखाजोखा राख्ने विश्वका फिजिसिस्ट, सिस्मोलजिस्ट, जियोलजिस्ट, क्लाइमेटोलजिस्ट, इन्भाएरन्टलजिस्ट, जियोडेसिस्ट, जियोमर्फोलजिस्ट सन्तुष्ट हुने विधि तथा प्रविधि अपनाउनुपर्छ । १९५३ मे २९ का दिन तेन्जिङ र हिलारीले सफल आरोहण गर्दा सगरमाथाको थाप्लोमा तेन्जिङले पहिले पाइला टेके कि हिलारीले भन्ने कौतूहल सबैलाई भयो । ती दुवैले हातेमालो गरी एकैपटक टेकेको जवाफ दिए । उचाइ मापन प्रक्रियामा पनि सबै विधि पुर्‍याइएको छ भनी विश्वलाई आश्वस्त तुल्याउने अवसर हो यो।
