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.
