- 3. INTRODUCTION A National Mapping Organization(NMO) is an organization, usually publicly owned, that produces topographic maps and geographic information of a country. Some national mapping agencies also deal with cadastral matters. In Nepal, Survey Department, which is only National Mapping Organization(NMO) of country, under the Ministry of Land Management and Co-operative Poverty Alleviation. An Spatial Data Infrastructure (SDI) is the technology, policies, standards, human resources, and related activities necessary to acquire, process, distribute, use, maintain, and preserve spatial data. In Nepal National Geographic Information Infrastructure Division (NGIID) play the main role as National Spatial Data Infrastructure Agency.
- 4. CO NT.. SDI IN NEPAL In Nepal, SDI is being developed as a tool for national spatial data collection, storage, processing and dissemination. NSDI is the common portal to use Geo-spatial data in effective and efficient way and link with other attribute database NSDI helps to reduce duplication of efforts, avoid redundant expenditures and eliminate corruption practices.
- 6. HISTORY NGIID Spatial data are created by several agencies as per their needs. Between 1999- 2002 Survey Department created the digital topographic database from its base- maps. Development of a multi-resolution geo-database is under progress. In year 2002, Government of Nepal realized the importance of supporting in the creation of an infrastructure to facilitate the sharing of geographical information within the country, then Government of Nepal has initiated the National Geographical Information Infrastructure Programme (NGIIP) for building NSDI since 2002. And now this program has been changed into National Geographical Information Infrastructure Division (NGIID).

- 8. CONT.. • Topographical Survey Branch is responsible for producing and disseminating various kinds of geospatial products including national topographic map series and administrative maps. • Geodetic Survey Branch is responsible for carrying out geodetic and astronomical surveys, such as establishment of the national network of horizontal control points, leveling survey, gravity survey, magnetic surveys, among others. • Cadastral Survey Brach is responsible for supervising the activities related to cadastral surveys and the first registration of real estate properties in the country. • Survey Office Strengthening Program is responsible for arranging required physical infrastructure for the Survey Offices at the district level. Survey Offices, expanded around the whole country, mainly at district level, is responsible for carrying out the activities of the Cadastral Surveys and the first registration of the real estate properties
- 9. CONT.. • National Geographic Information Infrastructure Project(NGIIP) was established as an initiative for National Spatial Data Infrastructure (NSDI) in the country. • In the present context, the primary focus is given to analyze and disseminate the Census 2001 added spatial dimensions, which is a new concept in Nepal. This will create awareness and the mechanism for data usage within other selected user organizations.
- 10. CONT..
- 11. • Mission: To strengthen planning and resource management in Nepal through the development of a geographic information infrastructure for the access of and related data for decision-making. MISSION AND OBJECTIVES
- 12. OBJECTIVES • The main objective of the division is to work as National Spatial Data Infrastructure Agency. The sub-objectives are: • To ensure easy access of geographical information. • To discourage redundancy in creation of geographical information. • To create environment for optimum use of geographical information. • To coordinate between agencies creating and using geographical information. • To develop and run national spatial data infrastructure clearinghouse and national geoportal.
- 13. MAJOR ACTIVITIES AND AVAILABLE DATA MAJOR ACTIVITIES To provide the topographical maps at different scale with digital database which covers the whole country. To develop an NGII platform to facilitate data sharing among Survey Department, Central, Bureau of Statistics and participating agencies. To provide hard copy maps of district, ward boundary and map of Nepal with district boundary and other administrative boundary. To provides information about Geodetic Control Network of Nepal established by Survey Department. Provides maps, aerial photographs, geodetic data, and other related data required for planning development, educational, administrative and research works by other agencies in Nepal.
- 14. CONT.. AVAILABLE DATA 1. National Topographic Database, NTDB NGIID made available the digital database of different scale. I. Topographic Database at scales 1:25 000 and 1:50 000 II. Topographic Database at scales 1:100 000 III. Topographic Database at scales 1:250 000 IV. Topographic Database at scales 1:500 000 V. Topographic Database at scales 1:1 000 000 2. Administrative Boundary 1. Metropolitan City, sub-metropolitan City, Municipality and Rural Municipality with was level administrative Boundary is now available from the division. it can also be downloaded from the website. 3. Orthophoto 1. Hardcopy map Orthophoto maps (hard copy maps)at scales 1:5 000 ( for core urban areas) and 1:10 000 (for sub urban areas) are also available.
- 15. CONT. 4. The population and Socio-Economic Atlas of Nepal • This atlas has been prepared with the joint effort of Survey Department and Central Bureau of Statistics of the Government of Nepal with the assistance of the European Commission. • Price: • NRS 2,500.00( in Nepal) • $ 200.00( outside Nepal) 5. Digital Soils & Terrain Database of Nepal version 1, 27 April 2004 (Rs. 2000.) 6. Geo referenced soft copy topographic base map • The latest base maps prepared by Survey Department at scales 1:25 000 and 1:50 000 have been scanned and geo referenced and are available at the resolution of 200 dpi. • Cost: Rs. 180. per sheet. • And others many.
- 16. Helps to reduce the duplication of spatial data, Support to access the data easily without any tedious, Easy to sharing, use spatial data within many agency, Easy to maintenance and improve the spatial data, ADVANTAGES
- 17. CHALLENGES Problem of communication. Problem of format. Problem of content and quality. Problem of price and licenses. how to evolve to incorporate new technologies; how to expand SDI concepts into the practices of business and smaller units of government; . There is lack of sufficient and adequately trained human resource to work with modern technology.
- 18. CONCLUSION • In conclusion we can say that, • In order to address the above challenges a standard national policy on SDI should be formulated and adopted. Should provide good communication facility. Should have good cooperation and data shearing between different organizations. should be incorporate new technologies and sufficient trained human resource to work with modern technology.
