Eos Locate™ for ArcGIS Apps

Underground utility mapping solution for ArcGIS users

Eos Locate™ for ArcGIS apps is the world’s first real-time, high-accuracy, underground-mapping solution for utilities using Esri software. With Eos Locate™ utilities can map their buried infrastructure (e.g., electric, gas, water, telecommunications infrastructure and more) with centimeter-level accuracy in real time, directly into their Esri software environment. All a field worker needs is an Eos Arrow GNSS receiver, either ArcGIS Collector or ArcGIS Field Maps on iOS, and a compatible locator device.

As of February 2021, Eos Locate is compatible with both ArcGIS Collector and ArcGIS Field Maps.

In Eos Tools Pro:

Esri Collector calls up the Locate page within Eos Tools Pro for automatic data calculations. Simply push the button on your locator and watch the two apps do all the work!

In Collector:

GNSS location metadata is combined with underground utility-locate data and sent automatically to Esri ArcGIS Online via Collector.


“Knowing where your infrastructure is, visible or buried, is a major step toward taking full advantage of the capabilities of ArcGIS Online. With Eos Locate™ for Collector, anyone managing underground assets can finally raise their confidence level in the accuracy and true location of their data.”

— Matt Piper, Global Director Industry Solutions: Utilities, Water, AEC & Infrastructure, Esri

“Seeing all that information from utility locators and GPS receivers packaged directly into a GIS application is exceptional!”

— Kelvin Cherrington, Eastern Regional Sales Manager, Vivax-Metrotech

“Previously, we were seeing that our old water mains could be off by up to 20 feet. With the new Eos Locate™ for Collector, we’re seeing that it’s accurate to under an inch.”

— Todd Chapman, Senior GIS Analyst, Indiana American Water
