Glossary for Geospatial Science

subobject:  A component of a TNTmips project file attached to a primary object.  A subobject contains data that describes some aspect of the primary object.  Examples: 1) map registration information is kept as a subobject (Regist) under the raster object it calibrates; 2) a pseudo-color table is kept as a subobject (ColMap) under the raster object it describes; 3) a HyperIndex subobject attached to a vector overlay polygon maintains the links TNTmips uses to retrieve that polygon’s associated daughter objects.
