How is stereo imagery used in satellite imagery?
Stereo Satellite Imagery is a form of Stereoscopy or 3D imaging. Two pictures are a take of the subject from two slightly different angles to produce the illusion of depth.
What can stereo image pairs be used for?
Stereo image pairs are used to make digital elevation models (DEMs). A DEM can be used to determine the boundary conditions of hydrothermal circulation and water budget analysis in a geothermal area. Geologic mapping can also be done more efficiently with the aid of Stereoscopy and other remote sensing techniques.
How are stereo images used in remote sensing?
In remote sensing applications photographs of the earth are taken and 3D topographic maps and computer models can be created using the stereo images.
