From a satellite photo to a clean base map.
Before the first cone or the first figure, someone redraws the road. LaneMarker traces it from the imagery — every curb, lane line, centre line, stop bar, crosswalk, median and turn pocket — then its drafting agents close the gaps and square the lines, and the sheet editor turns it into a plan set.
Built for the way engineers actually work.
Traced from the imagery
Drag a box along the corridor. Curbs, lane lines, yellow centre lines, stop bars, crosswalks, raised medians, islands and driveways are read from the aerial.
Drafting agents finish the base
Close kerb gaps, join traces, straighten lines and keep one layout per street — or box a mistake and let the agent redraw just that area.
Three sheet styles
Aerial, asphalt or clean linework on white, with layers you can move, hide and edit by hand.
Sheet production built in
Title block, north arrow, match lines, sheet index, lane arrows, sign sizes and your company’s sign and note templates.
3 steps. One map.
- 01
Trace the area
Drag a box over the corridor or intersection. The linework draws itself onto the paint.
- 02
Clean it up
Run the drafting agents, or edit any line by hand. Where the imagery leaves a real choice, it asks.
- 03
Sheet and export
Lay out the sheets and export to PDF or DXF, linework on its own layers.
Deliverables
- Base map linework
- Plan sheets — aerial, asphalt or linework
- Title block, match lines and sheet index
- PDF and DXF export
Exports to Word, PDF and images. Every value is editable and traceable to its inputs.

How accurate is the trace?
Does it work with my CAD?
