An Esri MapObjects application was integrated with Trimble GPS Pathfinder Pro XR/XRS software to provide a GIS-based field data collection and mapping solution for a large utility mapping project in Savannah, Georgia. This application has allowed surveying and facilities maintenance staff to collect engineering data and to map connectivity of multiple utility systems simultaneously in Esri shapefile format. This tool is linked to GPS technology to provide precise utility locations on top of existing GIS data, as well as to provide staff with real-time analysis of utility data such as material, diameter, and invert depths at upstream and downstream manhole locations.
