Grid Parameters for New DEMs

 

The grid can be created with:

  • UTM: pick the grid size in m.  You can force the UTM zone, which should only be done when you are at the edge of a zone and want to merge with data from the next UTM zone.
  • Lat/long: you can pick different values the lat (y) and long (x) spacing
  • Other WKT: you pick the WKT projection file, and the grid size in projected meters.  WKT grids can currently only be saved in MICRODEM format.

PixelIsPoint/PixelIsArea

Auto fill holes, and and the max gap to fill in grid cells when the grid is created when a grid is created from lidar or resampling an existing grid.
