"Most of India’s present repertoire of 13 operational remote sensing satellites with earth observation payloads, including the RISAT and CARTOSAT series, are assumed to be capable of providing high-quality earth observation imagery ranging from 50m to sub-meter resolution. These have swath coverage in the panchromatic range, from 10 kilometres on the CARTOSAT Series to 250 km in the RISAT series."
