Summary

Description

This is an Arc/Info coverage consisting of 7 points representing known coordinates on the earth's surface at Pipe Spring National Monument, Arizona. One geodetic marker was placed by the National Park Service; four markers are survey markers of the four corners of the boundary (they reflect mapping accuracy and not survey accuracy). Other markers need to be located and added to this coverage. The geodetic markers were collected by a Trimble GeoXT GPS unit with external antenna, Hurricane, and post processed in GPS Pathfinder Office 3.0 for differential corrections. The seventh point representing a geodetic marker was collected using a Trimble GeoXT GPS unit with no external antenna and post processed in GPS Pathfinder Office 3.1 for differential corrections.
