Gaussian Pyramid Downsample

On Raster GIS, Downsampling menu

For the current DEM

This could be used to take a 1 m lidar DTM, and create generalized grids at 2, 4, 8, 16, and 32 meters.   Alternatively you could create the lower resolution grids directly from the point cloud.

For a 0.4" grid, you could create generalized grids at 0.8, 1.6, 3.2, and 6.4 arc seconds
