We are happy to share this most recent publication in partnership with the University of Houston, TxDOT, and local groundwater conservation districts.

The paper describes the methodology performed on global navigation satellite system (GNSS) data collected in the field from monitoring stations in order to estimate site velocities (i.e., movement in the North-South, East-West, and Up-Down directions). The processed data are used by HGSD to understand changes in the land surface and are also provided to the public annually as part of the Annual Groundwater Report.
