What Customers Are Saying

Elisabetta DeGironimo

“Well we have received the Arrow 200 unit. It is awesome! It’s the easiest to configure GPS receiver that I’ve used in my 20+ years of GPS data collection.”

GIS Coordinator, Mohawk Valley Water Authority / NY, United States

Daniel Pankani

“Thank you so much for the exceptional support you have provided during our work with the Eos Arrow 100. My interactions with every one of your folks was pleasant and helpful.”

Dr. Patrick Crushell

“The level of accuracy we get—knowing we’re within a meter of the point we recorded before—gives us a higher degree of confidence. Five meters would skew our results quite seriously. The accuracy eliminates a level of uncertainty in our monitoring.”

Eos Locate for ArcGIS Esri Collector Field Maps Eos Tools Pro underground utility mapping GIS GNSS

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.

Eos Laser Mapping: Laser offsets and sideshots for Esri ArcGIS with Laser Tech LTI laser rangefinders and Eos Arrow GNSS receivers GPS mapping, total station like workflow

Eos Laser Mapping™ for ArcGIS

Eos is excited to bring you the world’s first laser mapping solution for Esri’s ArcGIS apps. The Eos Laser Mapping™ solution is for field crews that need to map hard-to-occupy assets with 3D, survey-grade accuracy — without having to physically stand on top of every single point. This is great when the assets you need to collect are located in environments that are either GNSS-impaired (with poor line-of-sight to positioning satellites), or in areas that are difficult and dangerous to reach. Eos Laser Mapping™ is currently available for iPad and iPhone as a free solution, in conjunction with our partnerships between Esri and Laser Technology (LTI).
