Data Acquisition

PWT performs data acquisition from diverse sources such as Global Positioning System (GPS) surveys, databases, and paper maps. To conduct GPS surveys, PWT Geographic Information Systems (GIS) specialists collect a geographically referenced position and import/migrate the data into the GIS format to build a GIS or to enhance or validate existing source data. Field data acquisition can be done independently or in conjunction with GPS data acquisition activities. PWT provides Quality Assurance/Quality Control ground control for our mapping and imaging projects to ensure the accuracy of point features that will be converted to GIS.
