At Dawson Geophysical, our survey department consists of six survey crews with seven to eight people per crew and numerous contract survey companies.  The in-house survey crews are comprised of a Head Surveyor, Assistant Surveyor, and five or six pack operators. Each crew runs Leica 1200 system gps units and is equipped with a base station and five backpacks. Opus (Online positioning user service) is used for processing control and Gpseismic is used for processing survey data. In the field, crews use garmin gps units for mapping while MapInfo is used in the office for crew maps.

From our Midland Field Office, the survey department handles the building of topo maps using All Topo Maps, the processing of control data, and quality control of field data before it is shipped to the client. The department also processes vibrator gps data and stakeless vibe data.
