Before GPS/GIS Utility Mapping begins, it is helpful to provide accurate information about the property, project scope, and areas that need to be mapped. Important details may include the site address, project boundaries, utility types, construction plans, existing maps, and specific areas of interest. This information helps the mapping team understand the project requirements and determine what data needs to be collected.

The site should provide safe and reasonable access to the areas being surveyed. If available, existing utility records, engineering drawings, as-built plans, previous survey information, and other relevant documentation can provide useful background information. Clearly identifying the project limits and any known utility locations can also help technicians organize fieldwork and collect the necessary spatial data more efficiently.

Depending on the project, technicians may combine GPS surveying, GIS technology, utility locating, GPR scanning, field measurements, and existing utility records to develop organized digital utility information. The collected data can then be structured into accurate digital maps and spatial records, helping contractors, engineers, developers, and property owners better understand existing infrastructure and support future planning, construction, and maintenance activities.
