MX (Cartosat-3)
Cartosat-3 four-band VNIR multispectral pushbroom imager for high-resolution land observation and cartography.
MX (Cartosat-3) is the four-band multispectral VNIR camera on Cartosat-3, separate from the mission's panchromatic PAN camera.[1][2] It is a passive optical multispectral imager with blue, green, red and near-infrared bands: 450-520 nm, 520-590 nm, 620-680 nm and 770-860 nm.[1] The payload uses 11-bit quantisation.[1] Ground sampling is 1.12 m [1] or 1 m [2]; swath is about 17 km [1] or 16 km.[2] Cartosat-3 and its MX instrument are operational/nominal in the mid-2020s.[3][2] The camera is built for high-resolution land observation and cartography, with capability for vegetation-index workflows, optical time-series change detection and supervised classification from VNIR imagery.[1][2]
Compositional position
None on record.
- Optical time-series change detection
Four-band VNIR optical imaging supports land-cover and infrastructure change detection when repeat acquisitions are available.
- Vegetation index mapping
MX includes red and near-infrared bands needed for standard vegetation-index mapping.
- Supervised tree-ensemble classification
Four-band VNIR data can feed supervised land-cover classification workflows.
