INTRODUCTION 2/26/2014 Spatial Data Infrastructure??? Its well-known.. A SDI should enable the discovery and delivery of spatial data from a data repository, via a spatial service provider, to a user Hence, the basic software components of an SDI are: a software client - to display, query, and analyze spatial data (this could be a browser or a Desktop GIS), a catalogue service - for the discovery, browsing, and querying of metadata or spatial services, spatial datasets and other resources, a spatial data service - allowing the delivery of the data via the Internet, processing services - such as datum and projection transformations, a (spatial) data repository - to store data, e.g. a Spatial database, GIS software (client or desktop) - to create and update spatial data 2
SDI IN NEPAL 2/26/2014 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 3

FUNDAMENTAL DATA SETS The fundamental data sets of Nepal is the National Topographic Data Base (NTDB) 2/26/2014 It contains the different layers such as geodetic data, administrative boundaries, transportation networks, buildings, Hydrography, Topography, utilities, Land cover, etc which is organized at sheet level The basis for NTDB is the digitization of topographic base maps of scale 1:25 000 for the Terai and the middle mountains and of scale1:50 000 for high mountains and Himalayas of Nepal. Furthermore, a large scale 1:5 000 to 1: 10 000 ortho-photo database is provided for densely populated urban and semiurban areas. 5
FRAMEWORK DATA SETS 2/26/2014 Database obtained from different sources of the related disciplines such as National Data base of Population Census, Agricultural, Soil, Geological, etc. The aggregation and integration of fundamental data sets and framework data sets solves the purpose of NSDI. 6
NGIIP 2/26/2014 Government of Nepal has initiated the National Geographical Information Infrastructure Programme (NGIIP) for building NSDI since 2002. Mission To strengthen planning and resource management in Nepal through the development of a geographic information infrastructure for the access of geographic and related data for decision-making. Objectives To develop an NGII platform to facilitate data sharing among Survey Department, Central Bureau of Statistics and participating agencies. 7

RECENT PROGRAMS: oJune The event concluded by drawing set of resolutions as follows: 2/26/2014 29, 2007: Symposium of Senior Policy Executives and Decision-Makers on Spatial Data Infrastructure. Resolution 1: SDI initiatives in Nepal developed as NGII is essential and necessary, and that it be promoted further. Resolution 2: A guiding policy statement on the importance of NSDI and Geo-ICT be stated in the National IT Policy and a comprehensive SDI Policy be formulated separately. Resolution 3: An appropriate institutional framework for SDI be approved by Government of Nepal under the umbrella of a National Geo-Information Council (to be formed) headed by National Planning 26 Commission and a National Geo-Information Centre
Resolution 4: All geo-data produces and users organizations contribute through de-facto participation in NSDI through publishing metadata of their data in the NGII clearinghouse and that they encourage their experts to participate in different Working Groups. 2/26/2014 Resolution 5: All geo-data produces and users organizations contribute to the promotion of NSDI through exchange and sharing of non-restricted data easily and freely (which means at a minimal cost); and in so-doing review and revise the pricing of their data to keep minimal. Resolution 6: The National Planning Commission take appropriate step to state the importance of SDI and a commitment for its promotion in the soon-to-be formulated three-years' Interim Plan which is due to be approved by Government of Nepal. 27
July 2, 2008: Workshop on Spatial Data Infrastructure and Disaster Management Following five technical papers were presented during the workshop: Spatial Data Infrastructure: Opportunities and Challenges (Mr. D.M.Kayastha, NGIIP) SDI and National Atlas (Mr. S.M.Shrestha, NGIIP) SDI and Disaster Management (Mr. S.K.Dhakal, NGIIP) SDI and Land Administration (Mr. S.N.Rajbhandari,DOLIA) Geomatic Education in the context of SDI (Dr. Bhola Thapa, KU) 2/26/2014 The workshop was attended by some forty officials representing different Ministries, Departments, Stakeholders and Universities 28
2/26/2014 The workshop concluded by drawing a set of resolutions as follows: Government of Nepal should take necessary initiatives to facilitate development of suitable infrastructures of geographic information and to establish Disaster Management Support System at appropriate level in the country National Policy of geographic information should be formulated and adopted. A high level geographic data/information committee be constituted with appropriate representation of all stakeholders to enhance inter-agency cooperation and also to manage all sectors related with spatial data and information, in order to achieve effective and sustainable development of geographic information. Also emphasized the need of establishing a National Geographic data/information Centre as an implementing agency of the proposed high level committee. 29
National Atlas signifies the level of development of a nation. Considering above adage, preparation of national Atlas should be expedited, the first step would be forming a committee of related experts. In order to facilitate informed decision making and also to support coordinated development of national geographic information infrastructure, all government agencies should take necessary initiatives to establish a GIS unit. Government of Nepal shall give highest priority in acquisition, archiving and distribution of updated information in all government agencies including survey department. Environment should be created to facilitate sharing of data among government agencies at minimal cost and with ease. 2/26/2014 30
in Nepal Administrative Staff College, Jawalakhel, Lalitpur June 18,2009 2/26/2014 “SDI Policy Framework in The Nepalese Context” The workshop was attended by sixty officials representing different ministries, departments, private sector, international organization, universities and civil servant trade unions. 31
The objectives of the workshop were: disseminate information on the latest status of NGIIP, share information about the works of private sectors and international organizations in the field of SDI, to obtain input from the professionals involved in the use and production of spatial data in order to make the national policy on SDI, to establish and strengthen cooperation, coordination and collaboration among the partners of the Nepalese SDI initiatives. 2/26/2014 32
Following four technical papers were presented in the workshop: 2/26/2014 1. Current status of NGIIP in Survey Department, Mr. D. R. Bhandari, NGIIP 2. Data Preparedness for Emergencies and National Spatial Data Infrastructure (NSDI) in the Nepalese Context, Mr. P. Kumar / Mr. P. Pr. Sapkota, UN OCHA 3. Development trend of SDI and the role of Private sector in building National SDI – An Experience of private sector involving in Spatial Data Preparation, Dr. B. R. Shrestha / Mr. S. Shrestha, Geospatial Systems Pvt. Ltd. 4. Need of policy on Spatial Data Infrastructure, Mr. N. R. Subedi, NGIIP 33
DISCUSSION IN PROGRAM 2/26/2014 Most of the participants took part in the open discussion session of the workshop. The following points summarize the discussion: data sharing culture should be developed, working with spatial data has been difficult due to lack of policy on spatial data, build a central data bank, updating of existing spatial data, develop a mechanism to secure the data, disseminate information about the existence of data, 34
DISCUSSION IN PROGRAM… private sector organizations can play positive role in developing SDI policy, develop national standard for spatial data, new generation of employees should be trained and given opportunity to work in the field of spatial data, publish metadata and share them wherever possible, develop national code for features and use them in practice, the participants highly appreciated the recent decision by the Government of Nepal to reduce the price of digital data being disseminated by SD, 2/26/2014 35
CONCLUSION 2/26/2014 In order to address the above concerns a national policy on SDI should be formulated and adopted. With this aim, it is recommended that the Survey Department constitute a policy drafting committee with appropriate representation of all stakeholders (public and private sectors). And present before all concerned before finalizing it. 36
