Glossary for Geospatial Science

arbitrary georeference:  A georeference that uses a matrix rather than control points.  Raster, vector, CAD, or TIN objects can have an arbitrary georeference.  An arbitrary georeference is created when an object with no georeference is used as a reference layer for creation of a new object in the Spatial Data Editor.  Note that you can make an object without a georeference in the Editor.  An arbitrary georeference allows you to correctly display related objects together.
