Locate Geodetic Control

Use the DSWORLD program to locate Geodetic Control using Google Earth as a map system.  DSWORLD is linked directly to the NGS database so you will always have the most current database.


DSWorld plots NGS network points by state, county and type (vertical or horizontal) in Google Earth. Google Earth must be installed prior to running DSWorld. NOTE: Because of changes to NGS web offerings, older versions of DSWorld no longer function. Please upgrade to the latest release:

NGS Database

This will take you directly to the NGS web page where you can search for control in different ways.
