Material and Methods
Analysis was carried out using the multi-resolution remote sensing data acquired during January 2010. Multi-resolution remote sensing data includes Ikonos (4 m), Landsat Series Enhanced Thematic mapper (28.5 m) sensor, IRS P6 LISS III sensor (5.8 m) and Modis data (500 m). Landsat data of Thematic mapper (28.5m) sensors for 2010 was downloaded from public domain (http://glcf.umiacs.umd.edu/data). MODIS data “MOD 02 Level-1B Calibrated Geolocation Data Set” were downloaded from EOS Data Gateway (http://edcimswww.cr.usgs.gov/pub/imswelcome).
IRS P6 LISS-III data was purchased from the National Remote Sensing Centre, Hyderabad (www.nrsc.gov.in). Geoeye Foundation provided Ikonos (4 m) data for academic use. Base layers such as city boundary, etc. were digitized with a negligible error count of 0.001from the city map (procured from BBMP: Bruhat Bangalore Mahanagara Palike), cadastral revenue maps (1:6000), Survey of India (SOI) toposheets (1:25000, 1:50000 and 1:250000 scales). Ground control points to register, geo-correct remote sensing data and Verify the output were collected using handheld pre-calibrated GPS (Global Positioning System), Survey of India Toposheet, Bhuvan and Google earth (http://bhuvan.nrsc.gov.in; http://earth.google.com).
