GPS & GIS utility mapping is the process of recording the location of underground utilities and infrastructure using Global Positioning System (GPS) data and organizing that information within a Geographic Information System (GIS). This creates a digital map that can be used to document utility routes, connection points, valves, structures, and other important site features.

Professional utility mapping services can be used to document electric lines, water pipes, sewer systems, communication cables, conduits, drainage lines, irrigation systems, and other underground infrastructure. GPS equipment helps capture field locations, while GIS software stores, organizes, and displays the information for easier reference and long-term asset management.

Using GPS and GIS utility mapping gives contractors, engineers, property owners, municipalities, and facility managers a clearer understanding of underground infrastructure. Accurate digital records can support future construction, maintenance, inspections, utility upgrades, emergency response, and site planning while reducing reliance on outdated paper drawings.
