MATERIALS USED

Urban dynamics was analysed using temporal remote sensing data during the period 1975 to 2010. The time series spatial data acquired from Landsat Series Thematic mapper (28.5m) and ETM sensors for the period 1975 to 1989 were downloaded from public domain (http://glcf.umiacs.umd.edu/data). Data pertaining IRS 1C of 2001 and 2010 (23.5m) were procured from the National remote Sensing Centre (http://www.nrsc.gov.in), Hyderabad. Survey of India (SOI) toposheets of 1:50000 and 1:250000 scales were used to generate base layers of city boundary, etc. City map with ward boundaries was digitized based on the city administration map.  Population data was collected from the Directorate of Census Operations, Bangalore region (http://censuskarnataka.gov.in). Table 1 lists the data used in the current analysis. Ground control points to register and geo-correct remote sensing data were collected using hand held pre-calibrated GPS (Global Positioning System), Survey of India toposheet and Google earth (http://earth.google.com, http://bhuvan.nrsc.gov.in).
