CARTOSAT is the one of the most advanced remote sensing systems launched by Indian Space Research Organization (ISRO) so far. In the history of remote sensing it is a milestone achieved by India.
It is the first in the CARTOSAT series and was launched in May 2005 by satellite launch vehicle PSLV-C6. It operates in panchromatic mode (black & white) in the EMR’s range of 0.50 micron to 0.85 micron. It carries two cameras to generate stereoscopic images. It provides spatial resolution of 2.5mx2.5m and radiometric resolution of 10-bit. Its revisit period is of 5 days.
The stereoscopic capability of CARTOSAT-1 gives it edge over many other remote sensing systems internationally. We can generate Digital Elevation Models (DEMs) and 3-D maps using its stereo-images. Apart from cartographic applications CARTOSAT-1 images are useful in resource management, pre & post disaster planning & management.
The second satellite of CARTOSAT series was launched in January 2007. It also operates in panchromatic mode with a spectral band of 0.50-0.85 micron. It is a very high resolution sensor system with less than one meter spatial resolution. Its revisit period is of 4-days.It will be highly useful for urban, rural planning and in cadastral level studies. It has already started acquiring images successfully. ISRO recently released some sample images acquired by CARTOSAT-2.
