Glossary for Geospatial Science

image map or georeferenced image map:� An image that has been processed to be like a map in appearance, scale, geometry, boundary, and projection with a degree of precision that satisfies the user.� Measurements made from an image map yield results equal to those made from the corresponding planimetric, topographic, or other map.� Similarly, either the image map or the conventional map can be overlaid and matched with the other.

For example, a 7.5' image map prepared in TNTmips from Landsat or SPOT satellite images will accurately match the corresponding USGS topographic map.� Similarly, the color scan of a topographic map that has been assembled by tiling and calibrated to map coordinates is an image map.� (See also: nominal image map.)
