INTRODUCTION

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

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

FUNDAMENTAL DATA SETS

The fundamental data sets of Nepal is the National Topographic Data Base (NTDB)

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 semi-urban areas.

FRAMEWORK DATA SETS

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.

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.

  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.

DISCUSSION IN PROGRAM

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,

04

35

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,

04

36

CONCLUSION

 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.
