The Arizona Water Science Center has been using survey-grade GPS since the mid 1990’s for several large studies, including the Lower Colorado Decree Accounting Project. Center staff continue to learn new ways to use survey-grade GPS in order to increase efficiency, data reliability, and to account for upgrades in technology.
Survey types/capabilities:
- Real Time Kinematic
- Single-baseline static
- Levelling
- Total Station
Examples of Survey-Grade GPS Projects:
- Stream gage datum
- Monitoring well datum
- Bathymetry
- Stream channel surveys
- Overbank/bankfull elevations for indirect discharge measurements/flood conditions
- Re-establishing survey control following hurricanes, floods, earthquakes, etc.
- Monitoring landslides/glaciers
- Measurements of earth deformation due to geophysical processes such as subsidence
- Monitoring coastal erosion
In addition to data collection, professional post-processing of the collected data can be completed quickly. Training can also
be provided to staff on their equipment and software.
