Thin surface command in open roads

Hello,

Does Open Roads have the thin surface command to reduce excessive number of points just like we used to have in Inroads ? How do I access the thin surface command in open roads ?

  • Unfortunately at the moment there is no thin command to reduce the size of an existing terrain model. Enhancement request exists.

    Tile/Tin filters are available when creating terrain model from point clouds.

    So one possible workaround is to export Terrain Model to XML,  do some few editing on the XML using excel to get only 3 columns X,Y,Z:

    1. rename .xml to .txt
    2. Open txt file using excel with text import wizard
      Start line 12 (where the coordinates begin)
      Separator space and <
    3. Search <F and delete all rows after last <P id=>
    4. Search/replace </P with nothing
    5. Keep only columns X,Y and Z
    6. export csv (rename as txt)

    Then attach  txt as point cloud in OpenRail (there is also spatial filtering at that step) and create terrain from point cloud using filter.

    Another one is to create raster grid using Scalable Terrain Model (reality modelling workflow) and create terrain model from file (tif).
    But following this workflow you first choose a grid to create the raster grid with no control of points except regular spacing.
