====== Image ======

The word image is a polysemous term and not always well defined. In computing, a bitmap image consists of a matrix of dots (called [[english:glossary:pixels|pixels]]) with associated color codes. In the field of GIS and geomatics, it is useful to distinguish between images whose pixels are a value from an electromagnetic sensor, often from [[english:glossary:remotesensing|remote sensing]], and images whose color codes were assigned for example by a scanner, or by attribute values, qualitative or quantitative. In GIS, an image often takes the form of a raster grid.
