Purpose: The Department of Defense (DoD) Strategic Environmental Research and Development Program (SERDP), Ecosystem Characterization and Monitoring Initiative (ECMI) is a long-term (more than 10 years) ecosystem characterization and monitoring program being conducted in conjunction with the host site at Fort Benning, GA. As part of this program, the U.S. Army Engineer Research and Development Center (ERDC) has developed a protocol to measure erosion/deposition dynamics in selected watershed areas on the installation (Figure 1). In order to accurately measure and remeasure the terrain surface over time, it was necessary to construct permanent ground reference points in the areas to be monitored. These reference points were accurately surveyed so that the data can be directly compared to previously collected data. The most precise way to survey these reference points is to use static Global Positioning System (GPS) techniques and other precision survey techniques. However, due to the number of sites to be monitored (more than 20), a static GPS network this large would be too costly to collect and to process the GPS data. It was decided that a combination of real-time kinematic (RTK) GPS techniques and static survey techniques would provide a much less expensive method to provide the necessary survey control at each site. A static GPS survey was used to establish a control network of high accuracy (first order standards). The reference stations (base stations) would then be used for RTK surveys to actually survey the instrument locations at the measurement sites.
