Cost Effective and Accurate Data
GIS relies on data input from a variety of sources, such as subsurface utility
engineering (SUE), ground penetrating radar (GPR), global positioning systems (GPS) and photogrammetry. Data such as location of roads, utility lines, wetlands, etc., is stored as a collection of layers that can be stacked to get a true picture of a particular location or to create a digital model of the earth. Quicker and more efficient than manual methods, GIS’s digital data can be manipulated a variety of ways and stored on disk, eliminating paper maps and charts.
