Space Imaging announced that imagery from India's RESOURCESAT-1 satellite is now available to the commercial marketplace. Space Imaging has the exclusive worldwide rights to sell data from RESOURCESAT-1 outside of India.

Imagery from RESOURCESAT-1 is available in 5-meter, 23-meter and 56-meter resolutions and is ideal for mapping, urban development, environmental monitoring, agricultural monitoring, land use planning, coastal monitoring, disaster assessment and risk management. Imagery from the satellite is comparative to imagery from the Landsat satellites.

A variety of imagery products with different spatial resolution are available from RESOURCESAT-1:

Imagery from the LISS-4 (Linear Imaging Self Scanner) sensor is sold at 5-meter resolution and has an option of either panchromatic or three multispectral bands in the visible and near-infrared region. The swath width of the panchromatic imagery is 70.3 km and the swath width of the multispectral imagery is 23.9 km.
Imagery from the medium-resolution LISS-3 sensor is sold at 23-meter resolution and has four spectral bands in visible, near-infrared and short wave infrared. The swath width is 141 km. The revisit is 24 days.
Imagery from the AWiFS (Advanced Wide Field Sensor) sensors are sold at 56-meter resolution and has four spectral bands in visible, near-infrared and short-wave infrared. AWiFS imagery is sold with a swath width of 350 km. The revisit is 5 days.

All imagery falls under Space Imaging's Geo family of products and are georeferenced. Prices start at $700 per scene for AWiFS imagery and $2,500 per scene for LISS-III and LISS-IV scenes.

In addition to increased resolution, other major improvements have been made to RESOUCESAT-1 as compared to India's earlier IRS-1C and IRS-1D satellites that have far outlived their designed mission lives.

Imagery is now available anywhere in the world since RESOURCESAT-1 has 120 Gigabits of on-board memory unlike the previous IRS satellites. Pixel bit depth has also been improved to 7-bits (derived from 10 bits) for LISS-IV and LISS-III, and 10 bits for AWiFS.
