world bank funded gis based web enabled environment database of gujarat
DESCRIPTION
75 manmonth World Bank funded project to create GIS based Web Enabled Gujarat’s Environment Database – the first and largest of its kind in India. The data was collected through in-depth study of specific components of Gujarat’s environment over a period of 5 years by some of the well-known Institutions of India. The project included environmental mapping of Gujarat State (more than 300 maps with around 2000 attribute tables) + Maps of 26 districts, 274 talukas, & 18000+ villages of Gujarat StateTRANSCRIPT
GIS based Environmental Database on Gujarat
Mandar Mehta, GIS Advisor
Aims & Objectives Aims
Informed decisions at all levels Environment Management Capacity Building for
GEC Objectives
For GEC: The database gets organized for easy storage, retrieval,
maintenance and updation Establishment of Systems for procurement of data from
providers of data Establishment of logistics for dissemination of
environmental informationFor users:
Wider and instant access to environmental information Improved visualization Better appreciation of cross sectoral and spatial linkages
For Data Providers: Quality of data gets improved due to increased
transparency and pressure from constant public peer.
Outcomes Database related
To develop a comprehensive ecological database management system on a GIS platform as well as web
To serve as Central Data Repository of Environmental Information on Gujarat
Use of data for modelling exercises in future. To integrate Regional level data/ analysis of region specific studies
to the State level information
Capacity Building To build up inhouse capacity within GEC on storage, analysis,
management and dissemination of environmental information To train users on GIS based access of environment information
Dissemination Related To Store, Retrieve and disseminate environmental information in a
GIS usable form through internet To instantly make available GEC and SEAP reports from the website To make the database available through CD containing Thematic
Maps and data To publish an Environment Atlas of Gujarat
