NAVD88 Elevation Circuit


This page displays information about the NAVD88 Elevation Circuit developed by the Pima County Department of Transportation and the City of Tucson Department of Transportation & Mobility. Circuit segments are displayed on an interactive PimaMaps map and are linked to scanned documents of Survey Field Book pages for each segment. Circuit segments on the map are used as an index to the Survey Field Book pages. You can also find segments by street name or book/page. For horizontal control, see Geodetic Control Points.

The survey that determined the Elevation Bench Marks was for the purpose of controlling the Pima Association of Governments Regional Orthophoto Project.
