PRISM

0-5 cm soil moisture data was taken with Hydraprobe Data Acquisition System (HDAS) instrument at each sampling location (minimum of three independent measurements per location if readings vary widely take more) with coordinates automatically given by the HDAS system. The HDAS measurements will be made across regular grids of 50m. The planned sampling locations for each focus area will be loaded onto the HDAS, and visible on your screen via the ArcPad GIS software. Sampling involves navigating along the sampling transect through the use of the GPS in-built in the GETAC that forms part of the HDAS system, which displays the real-time position on the same ArcPad screen as the sampling locations. Once the GPS cursor is located at the predefined sampling point, HDAS measurements can be made and stored in the GETAC.
