Step 1

Input features

Upload or paste standard GeoJSON or TrueGIS Layered JSON. Points, lines and polygons are considered together.

Step 2

DDP geometry

Scale Custom scale Usable map-frame width millimetres Usable map-frame height millimetres Overlap percent Input buffer Buffer unit

The usable map-frame dimensions—not the paper name—determine each DDP rectangle. Pages stay flat and north-up with no rotation.
