Generate georeferenced and magnetic north aligned .omap files directly from lidar data

An application for generating orienteering maps (.omap file) from ground-classified lidar data.

With a GUI with parameter tuning, area filtering and lidar conversion tools. The written omap-file is automatically georeferenced.

Overlapping lidar files not yet handled

Implemented:

  • GUI with live map parameter tuning
  • Raw, smoothed and interpolation-based (experimental) contours
  • Basemap-contours (with marked depressions)
  • Vegetation
  • Writes Omap-files that are
    • georeferenced (if a CRS is detected in the lidar files or provided)
    • aligned towards the Magnetic North according to the world magnetic model based on the maps creation date and geographical position
    • correctly scaled including calculating the auxiliary scale factor based on the map center's elevation
    • in scales 1:10_000 or 1:15_000 with minimum symbol size filtering
  • Supports both bezier and polyline output
  • Polygon filter for only mapping parts of the provided lidar files
  • .las and .laz to .copc.laz conversion
  • Coordinate system assignment tool for CRS-less lidar-files (Lantmäteriet in Sweden uses EPSG:3006, but often skips writing the mandatory CRS-VLR to their files)
  • CRS-less files are supported if the CRS is unknown
  • Non-connected lidar file detection (Useful when accidentally adding a file that should not have been added or assigning the wrong CRS to a file)
  • OpenStreetMap or OpenTopoMap background map
  • Experimental lidar-intensity filter
  • Buffering on polygons to remove small holes and too thin areas or exaggerating small details

WIP:

  • AI contours
  • Form lines

Wish List:

  • Water detection
  • Building detection
  • Vegetation boundaries
  • Stream detection
  • Boulder detection
  • Road/path detection
  • Marsh detection
  • Lidar CRS transformation
  • Overlapping Lidar handling

Parameter tuning in OmapMaker

Tune the map parameters on a test tile before generating the whole map

Adding a polygon filter to lidar files

Add a polygon filter. Only lidar points inside the filter are used in map generation
