Glossary for Geospatial Science

cell:One value in a raster that corresponds to a specific area on the ground.� A raster cell may contain a value that describes the elevation above sea level at one position in a survey site or the intensity of red radiation for a pixel in a video image.� For convenience, a raster cell is usually thought of as square or rectangular, although many image collection devices actually measure circular or elliptical areas.� If a raster object is created from a screen image, each cell value represents one pixel.
