Glossary

Shareloc common words and shortened terms are detailed here.

CARS: means CNES Algorithms to Reconstruct Surface (ou Chaîne Automatique de Restitution Stéréoscopique en français) See CARS Documentation
CRS: Coordinate Reference System characterize location on earth.
DEM: Digital Elevation Model. Usually means all elevation models in raster: DSM, DTM,…
DSM: Digital Surface Model. Represents the earth’s surface and includes all objects on it. CARS generates DSMs. See Digital Elevation Model
DTM: Digital Terrain Model. Represents the earth’s surface without the objects.
EPSG: EPSG Geodetic Parameter Dataset (also EPSG registry) is a public registry of geodetic datums, spatial reference systems, Earth ellipsoids, coordinate transformations and related units of measurement. See EPSG
LOS: Line of Sight is the viewing ray at a given position of the sensor.
Rectification: Image rectification is a transformation process used to project images onto a common image plane. In CARS, the epipipolar geometry rectification is used.
RPC: Rational polynomial coefficient is analytics compact representation of ground to image mapping.
ROI: Region of Interest means a subpart of the data. It can be defined by it’s extent.
