DDP coverage optimiser

Three steps: add the geometry, accept or override the scale, then create the DDP map series. TrueGIS handles the minimum-sheet search, exact checks, guaranteed coverage and logical numbering automatically.

Step 1

Add geometry

Choose one input method. Points, lines and polygons can all be used.

GeoJSON / Layered JSON

Draw on the map instead

Step 2

Scale

Automatic is the normal choice. TrueGIS starts detailed and, if the geometry is too large, steps through the same rounded scale list as Scaled Print all the way to 1:20,000,000. Choose a manual scale only if you want to override it.

Defaults: 277 × 170 mm usable frame, 10% fixed overlap, no buffer. DDPs remain flat and north-up.
