Frequently anticipated questions:


What does this data set describe?

Title: TERTIARY CONTROL POINTS FOR BOULDER COUNTY
Abstract:
NOTE FROM THE COUNTY SURVEYOR: The survey for these Control Points was performed in 1998-2000. Some of these Control Points have been destroyed. Horizontal Data Information may not be current, due to subsequent revisions in federal Geoid models. Because of budgetary limitations, this network is not regularly maintained by Boulder County.
