In September, 2008 the Hon’ble Minister (S&T and ES) has informed DST and<br />

SOI to expedite the creation <strong>of</strong> data on 1:<strong>10</strong>,<strong>000</strong> <strong>scale</strong> from suitable satellites (for<br />

priority areas) and to make use <strong>of</strong> the very narrow window in October 2008 for cloud<br />
