AERIAL SURVEYING                               

At NavTech we have a long working relationship with photogrammetric firms. We can deliver finished base maps of your project tied into the state plane coordinates and USGS datum.

Mapping datum: Horizontal position is the North American Datum of 1983 (NAD 83), the Vertical Datum is the North American Vertical Datum of 1988 (NAVD 88).

Our experience is crucial in determining the best methods to gather the necessary data to deliver the base mapping our clients require.
