Glossary for Geospatial Science

level:  In HyperIndex, any object or file that is displayed in the Display / Spatial Data window is called a level.  A level may originate from a raster, vector, or CAD object.  However, in HyperIndex, the level assumes an identity beyond that of the object or file itself, because the level includes the index areas that have been defined and any links to other objects.  Thus, in addition to being an image, a level lets you access many different kinds of information.  (See also: HyperIndex, index area, link, stack.)
