The OCAD workflow
Two exports from one OCAD file — guaranteed pixel-perfect alignment.
Routster needs two views of every map: the color map the runner sees, and the impassability map the algorithm uses to decide where routes can and can't go. Following these steps exactly guarantees the two layers line up perfectly.
Step A — Export the color map (the visuals)
1
Open File → Export (Ctrl+E)
Choose TIFF (full color) as the format.
2
Set resolution to 508 DPI
This is critical — Routster's scaling assumes 508 DPI. Any other value and the route overlays will drift.
3
Select 'Entire Map'
Do not crop manually. Let OCAD compute the bounding box.
4
Save the .tif file
This is your visual upload.
Step B — Export the impassability map (the logic)
1
Toggle Map → Show Impassable Objects
The map switches to show only forbidden elements (fences, buildings, deep water, dense undergrowth).
2
Save as TIF
OCAD will reuse the 508 DPI / Entire Map settings automatically.
Don't change the bounding box between exports
If the color and impassability TIFs have different dimensions, every route on this map will appear shifted. Re-export both whenever you edit the OCAD source.
Upload both files and the system will bind them together. From there, tune the algorithm with the parameter guide.
