Where the data came from. How much it can be trusted. Who owns the land. What the ground is doing today, and when it was last checked.

This is a real card for a real road, and not a flattering one. It rates the road map-inferred, low confidence, warns that it crosses private land, and tells you to verify locally.

Every line says how much to trust it.

A designated forest road and a bare track are not the same thing, and no other off-road map admits the difference. TerraRoam draws them differently and lets you filter by grade.

Agency verification is US-only today, sourced from USFS motorized-use maps. Abroad, map-inferred is the honest ceiling, and TerraRoam says so rather than implying more.

Turn on what the trip needs.

Difficulty and rig fit. Fire, smoke, snow, soil and wind. Public land, private land and no-go. Fuel, water, mechanics and ranger stations. Nothing you don't need.

I built the tool I wanted to have with me.

Mike
FOUNDER · US ARMY VETERAN

I've been building geospatial software and spatially aware solutions for a decade. Off-road, I kept heading out with half an answer; I could find a trail, but not whether my Wrangler could clear it, whether last week's rain had taken the road out, or whether I could even be there.

Other apps answer some of this. None of them answer it all, and certainly not at any sort of scale, so I built the platform I wanted. And where the data is thin, I'd rather say so than guess, because integrity is core to TerraRoam.

I hope you'll come along with me on this journey.

Built for the long way home.
