Client Testimonials

We've used Nohea at Imi Systems to locate and mark water lines during tree work to not damage any underground piping during removal. The tree root mapping was also very useful to tell when a tree growing close to a house might pose a foundation structure risk.

What Tree Services
We utilized ʻImi Systems to complete drone mapping of our wetland area prior to grading, creating a clear baseline for the site. The before-and-after aerial data allowed us to monitor changes accurately throughout the project. Their mapping provided valuable insight for planning, documentation, and long-term site management
