Trail Mapper

TrailMapper is built for trail contractors, property owners, and outdoor builders who need accurate GPS trail records they can actually work with — not just a line on a screen.

Walk your trail lines while TrailMapper records the GPS path in the background. Connect segments into a full network, drop in points of interest, then export everything as a KML or GPX file. Your client opens it in Google Earth or OnX and sees exactly what got built.

Free to use on up to 2 properties. Upgrade to Pro for unlimited properties, backup, and file import.
