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
