Is there a way to control the origin point of the resulting raster when interpolating from a LAS tile?
I have a large collection of regulate .las tiles with some overlap between tiles (1,000m tiling system with 50m overlap so 1,100m x 1,000m total tile size). I want to individually interpolate using IDW or Discrete Sibson as needed, but ensure that resulting rasters have the same underlying grid so that there is no need to re-interpolate when merging the rasters. As it stands, when i interpolate multiple files they all are on slightly different grids. My work involves tracing small artifacts like walls and ditches that get lost quickly if I process too much. Methods considered so far:
- Create artificial LAS points at the exact corners of each original .las file and merge to create a file with the exact bounding box of the tiles
- Do the same thing in Whitebox after converting each .las file to .shp
Both methods seem to work but require more automation then I have the skills for. If there is some way I am missing to just make each instance of LiDAR interpolation in Whitebox adhere to a grid that I set that would be much easier.
