Geoinformatics for Urbanisation and Urban Sprawl pattern analysis

Survey of India (SOI) toposheets of 1:50000 and 1:250000 scales were used to generate base layers of taluk boundaries, city boundary, drainage networks, and water bodies. Field data were collected with a handheld GPS. Remote sensing data (spatial and spectral resolutions are listed in table 1) used for the study are:
