Satellite Stereo Images consists of two satellite images of the same area on the Earth, taken from two different angular perspectives during one orbital pass of the satellite. The pair of images collected shows at least 40% of overlap and are collected on the same ground path just few seconds apart, to maintain tonal consistency between corresponding images. The correction, adjustment and creation of seamless mosaic for such highly meticulously procured satellite images require precise geometric correction that is assigning map coordinates to the image data. Hundreds of images with very few Ground Control Points (GCPs) can be processed and their misalignment problems associated with mosaicking can be solved in short span of time, with less finance and higher geographic fidelity.

Stereo satellite images have the potential to create Digital Surface Model (DSM) or Digital Elevation Model (DEM) of an area. These images possesses the ability to extract appropriate  geo-coordinates and altitude (x,y and z) of geographic and manmade features like hills, forests, roads, buildings, trees etc.. Stereo Images find importance where accurate elevation data is not easily available. The basic area of its application includes mapping, telecommunications, transportation, urban planning, environmental management, exploration, mining and forestry.
