Eos Locate™ for ArcGIS®

Bring your buried assets to life! Accurately mapping buried legacy pipe has traditionally required dig spot holes, physically exposing the buried pipe, and then capturing its location. This is time consuming, expensive, and inconvenient for everyone who lives and works in the area. Are you ready to bring your buried assets to life without digging? Eos Locate™ for ArcGIS® is the world’s first real-time, survey-grade underground mapping solution for ArcGIS. With Eos Locate™ , it takes just a few seconds to locate and map buried infrastructure with highly accurate coordinates and depth below cover, directly into ArcGIS. This solution drastically cuts down time and labor spent in the field remapping existing utilities, while improving the accuracy of geospatial records.
