One-tap recording
Start, walk, stop, name it, save. Anybody with the field app and the right role can record a line, which is what turns one surveyor into a whole crew.
GPS recording · on the trail
Walk the line. The rest is already done.
Hit record, walk or ride the alignment, hit stop. What you get back is not a raw track to clean up later — it is a trail with its distance, climb, grade profile and terrain read already worked out.
What the recorder does
A surveyor in every crew member's pocket
No desktop GIS, no exporting, and no "send me the GPX and I will deal with it later" — which is where most recorded lines go to die.
Works with no signal at all
GPS is a satellite fix, not a data connection. The recording continues in the deepest valley on your property and uploads itself when the phone finds a bar.
Typed notes as you go
Drop a waypoint where the line needs a structure, a rock feature or a drainage break, and it stays attached to that point on the alignment.
Terrain read from the line
Grade, side slope and fall-line stretches sampled along what you actually walked, scored against sustainable trail-building rules rather than a rule of thumb.
Edit the shape afterwards
Drag vertices on the map to smooth a wobble or trim an end. Every point you walked is kept on save — the simplifier is a tool you reach for, not something applied behind your back.
Promote it to a real trail
When the line is agreed, export it into your trail network with its geometry, its grades and its notes intact.
After the walk
The part that used to need an office
A recorded line is the input to a decision, and the decision usually involves somebody who was not there.
Analysis
Is this a line that will last?
The planner reads the ground under the alignment and says where it does not hold up: stretches running the fall line, grades above what the half-rule allows for that side slope, the places drainage has to go. Red on the profile is not a veto — plenty of good trail has short steep sections — it is the list of what will need attention.
- A sustainability score with reasons From measured samples along the line, with the stretches that pulled it down named.
- Where the water will go Drainage break counts derived from the grade profile rather than guessed at.
- Activity-aware A ten-foot groomed corridor and a two-foot hiking bench are held to different envelopes.
Sharing
Send it to somebody who was not on the walk
A landowner, a board or a client does not want a GPX file. Share a recorded line as a page: the map, the elevation profile, the notes you dropped, and — if you want it there — what it would cost to build.
- One link, no account A page anybody can open, which you can stop sharing for good at any point.
- Several lines as one job Group a season's alignments into a project and it prices as one visit rather than as several.
- Costs are optional Hide the estimate per proposal for a tender, or switch build costs off for the whole workspace.
Getting started
Record your first line this week
The setup is an app install and a role. The rest is a walk.
01
Install the field app
Free on iOS and Android, and free on every plan including the free one.
02
Download the area
Map, terrain and photos onto the phone before you leave, so the far side of the property behaves like the near side.
03
Walk it and save
Record, drop notes where they belong, stop, name it. The numbers are worked out for you.
04
Decide, then promote or share
Read the analysis, adjust the line on the map, and either export it into the network or send it as a proposal.
Turn a walk into a plan
Start free and record your first alignment with the crew you already have.
