The GCDB Handbook for GIS is a quick reference to the practical applications of the Bureau of Land Management's Geographic Coordinate Database for Geographic Information System users and land surveyors. Because the GCDB is important to GIS in the Public Lands Survey states, GIS users and land surveyors should understand what the GCDB is and how the GCDB affects GIS data alignment and spatial accuracy, and should know how to use the GCDB for a number of GIS and surveying tasks.
