Terrain Mapping Camera-2 (TMC-2) is a follow-on of the TMC on-board Chandrayaan-1. TMC-2 provides images (0.4μm to 0.85μm) at 5m spatial resolution & stereo triplets (fore, nadir and aft views) from a 100 km orbit for preparing Digital Elevation model (DEM) of the complete lunar surface. The triplet images from TMC-2 when processed into Digital Elevation Models, enable mapping of surface landform morphologies. These include

• Craters (formed by impactors)
• Lava tubes (potential sites for future habitability)
• Rilles (furrows formed by lava channels or collapsed lava tubes)
• Dorsa or wrinkle ridges (formed mostly in Mare regions depicting cooling of and contraction of basaltic lava)
• Graben structures (depicts the structural dislocations on the lunar surface )
• Domes/ Cones (denoting localized vents of past volcanism on the Moon).

The derived information facilitates estimation of dimensions of above features and its comparison for reconstructing the morpho-structural framework, crater characterization to derive impact geometries, surface age determination through Crater Size –Frequency Distribution (CSFD) methods, Rheological analysis based on the derived morphometric parameters, Lunar reflectance estimation etc.
