Wanted auto split and create DEMs
June 11, 2020
…and for many other operations.
For master AOI:
- divide into grid of X by X units
- for each tile: expand poly by margin%
- generate DEM tiles
- clip all tiles by initial poly size
- merge/mosaic all clipped tiles
- erase intermediate
Raster processing is much faster in squares. Optimise the grids, maybe a "least squares" approach?
Where is the sweet spot in raster dimension size for "most done at once" conjunction with "fastest processing"?
Why hasn't this been done already?
