Glossary for Geospatial Science

image:� Any analog or digital two-dimensional array of values whose spatial interconnections convey useful information.� Image has a wider sense than photographs, TV, or human vision.� A photographic print is an image but an image is not necessarily a photograph.� What a human sees can be called an image but image is not restricted to describing human vision.� The raster scan of a color map is an image until it is reduced to a vector object.� However, the display of a vector object on the monitor creates an image of that vector file.� Properly, that which is stored in a raster object can be called an image, but that which is stored in vector, text, or database objects cannot.
