Global Mapper v25.0

How do I filter\export a very dense .las (10cm) to a courser .las grid spacing (1m)?

The Lidar LAS/LAZ Export Options are just filtering by elevation, height above ground, color, class, return type, scan angles, intensity, NDVI, and NDWI.

    When you load your las file you can check "Use Preview Mode" and load only 1 of every 6 samples, or whatever would give you the point density you want.  Then you save this as a new las file, with a different name than the original you loaded.  The new saved file will have less point density.  This works with v16.2.
