The Field Survey Section performs this array of surveying tasks utilizing some of the most efficient, technologically advanced equipment available. Robotic Total Stations, High Definition Surveying (HDS) and Global Positioning Satelites (GPS) receiver units are used in conjunction with data collection and construction staking software which enable timely, accurate and cost effective delivery of survey information.

Survey data collected in the field is processed by the Boundary Analysis and Computer Processing Units of the Survey Field Section. Maps and reports, both paper and digital are prepared for use in OC Public Works design and construction projects, flood control studies, deformation monitoring studies, cadastral and/or control adjustments, and many other evidentiary purposes.

This information is compiled into record information filed in the County G.I.S./L.I.S. for use by the general public and the surveying/engineering community.
