IRS-1C applications for land use/land cover mapping, changedetection and planning

摘要

Remote sensing applications using IRS-1A and IRS-1B data hassuccessfully demonstrated the capabilities in generation ofdistrict-wise land use/land cover maps, depicting the information up tolevel-II on 1:250,000 scale which are being used as a basic input inland use planning of the 15 agro-climatic zones in the country. Thelaunch of IRS-1C on 28 December, 1995 provided a new dimension in theapplication capabilities, in particular for land use/land cover mappingon various scales and levels for use by a diverse user community. Ananalysis has been made in the present paper on the capabilities ofWide-field Imaging Sensor (WiFS), Linear Imaging Self ScanningSensor-III (LISS-III), Panchromatic sensor data for land useapplications. It was observed from the above studies that WiFS data isuseful in extracting land use/land cover information at Level-I for useat National/Regional level applications, LISS-III data useful inextraction of information at Level-II/III for use at District/Tehsillevel applications and Panchromatic data has the capability to provideinformation at Level-III/IV for use in Cadastral and Urban applications
