High Resolution 1:10,000 scale Mapping Strategy of Multi ... - NDMA

The following methodologies may be considered for the generation of 1:10,000
database:
Remote sensing makes it possible to collect data on dangerous or inaccessible
areas. Remote sensing applications include monitoring deforestation in areas such
as the Amazon basin, the effects of climate change on glaciers and Arctic and
Antarctic regions, and sounding of coastal and ocean depths. Military collection
during the cold war made use of stand-off collection of data about dangerous border
areas. Remote sensing also replaces costly and slow data collection on the ground,
ensuring in the process that areas or objects are not disturbed. (For more details
please refer to Annex. IX)

VARIOUS METHODOLOGY AVAILABLE FOR
PROCUREMENT OF 1:10,000 IMAGES
SATELLITE IMAGING
More and more, high and very high resolution optical space sensors are
available. Ground Sampling Distance (GSD) of the imaging system of optical space
sensor is an important value, also the type of imaging with a Transfer Delay and
Integration sensor (TDI) or by reducing the angular speed with a permanent rotation
of the satellite during imaging is important, like the accuracy of the attitude control
and determination unit. The radiometric and spectral resolution has to be taken into
account. For operational use the swath width, viewing flexibility and imaging capacity
