Completed Project : National Land Use/Land Cover Mapping using Multi-temporal Satellite Data (2nd Cycle)

National Land Use/Land Cover Mapping using Multi-temporal Satellite Data (2nd Cycle)

The change detection through satellite remote sensing in temporal and spatial domain offers the most economical means of assessing environmental impact, monitoring of biodiversity of an ecosystem and generation of suitable action plans for sustainable development. The satellite data of various resolutions are used for preparing natural resources information layers of land use/land cover, soils, land degradation, wet lands, geomorphology etc. on 1:50000 scale periodically for monitoring the state of natural resources. The first cycle of the nation-wide land use/land cover mapping on 1:50000 scale using IRS data was completed in 2005-06 for the country. Land use/land cover is dynamic in nature and requires regular monitoring to understand areas of rapid change and to ascertain the reasons for change. With this in view, the NRSC has entrusted this project to KSRSAC.


Objectives

To generate land use/land cover map of 2011-12 for Karnataka using three season IRS data to generate land use/land cover change matrix by comparing this data with that of 2005-06 data and to identify areas of major land use changes.

Land use/Land cover 2011-2012

Summary Of Work

On-screen image interpretation of three season IRS data of the year 2011-12 was done to generate land use/land cover map of Karnataka. The land use/land cover statistics generated for the state for the year 2011-12 were compared with the LU/LC data generated earlier in the year 2005-06 to see the change in LU/LC classes and to finally identified areas of major change from 2005-06 to 2011-12.
