Topographic annotation

Freeline-draw on real terrain — every stroke snaps to the imported model.

Import a topographic model — a DTM, drone survey, GIS mesh, or LiDAR scan — and freeline-draw on top of it at full landscape scale. Every stroke clings to the terrain surface. Mark a trail edge, a cutblock boundary, a property line, a survey transect, a grading cut-and-fill, a drainage path. Works on-site, offline, on a tablet you can hold while walking the ground. Export polylines into Rhino, Civil 3D, QGIS, or a GIS pipeline.
