Differential Global Positioning Systems are enhancements to the Global Positioning System which provide improved location accuracy. GCPs (Ground Control Points)  in the ortho-rectification process as well as Georeferencing the scan cadastral maps, or any engineering Survey application, they need to be extremely accurate. Ground control points are initially taken from survey grade instruments such as DGPS and RTK-GPS. We use these points during processing of the images to reduce the error in the final output to obtain survey grade accuracies.
