Global Positioning System (GPS) technology is used within the Environmental Division in a number of ways. Environmental constraints, which include archeological sites, wetland areas, and hazardous waste related locations, are collected in the field with our GPS equipment. Another application of GPS is for real-time navigation. The capability to load data such as digital construction design plans, aerial imagery, topographic maps, or any other resources that can be incorporated into the GPS units for use in the field for real-time navigation.
The Trimble GeoXH handheld GPS unit is the primary piece of equipment that we use. Our current GPS inventory includes:
-
2 Trimble 2008 GeoXH handhelds
-
3 Trimble 2005 GeoXH handhelds
-
7 Trimble 2003 GeoXT handhelds
-
1 Trimble GeoBeacon
-
2 Trimble ProXR receivers
The GeoXH handheld units are able to receive real-time correction signals from either our GeoBeacon, which is made wireless through Bluetooth technology, or from WAAS (Wide Area Augmentation System) satellites. Also, the Division has two Contour laser range finders that can be connected to the GPS units to collect offsets.
