For GPS/GIS utility mapping, accurate project information and access to the areas being mapped are important. Clients should provide the project boundaries, site plans, existing utility records, property information, and details about known underground infrastructure whenever available. Information about the intended construction, excavation, or development can also help determine the required mapping scope.

Professional GPS/GIS utility mapping requires high-accuracy GPS equipment, GIS software, and trained mapping technicians. Technicians collect precise coordinates and attribute information for water lines, gas lines, electrical systems, telecommunications, sewer infrastructure, and other utility features. Depending on the project, utility locations may first be identified through field locating methods and then recorded as accurate spatial data within a GIS system.

The work area should be accessible and reasonably clear of obstacles so technicians can safely collect reliable field data. After the survey and data collection are completed, the information can be organized into digital utility maps, GIS databases, and other project documentation. Providing accurate site information and clear project requirements helps ensure consistent mapping, better data organization, improved project planning, and reliable utility records for future construction and maintenance.
