Non-rectangular update grid #61

Closed Devaraj-G closed 3 years ago

Devaraj-G commented 3 years ago

Can remove-restore handle non-rectangular update grids?

Instead of feeding individual DEM files to remove-restore, one can mosaic them using gdal_merge.py and feed it as one update grid. This is very suitable for NONAA100 (98 files) + NONAA10 (7008 files).

e.g. Spead of NONNA100 and NONNA10

Yes, it breaks an input grid into a list of points before applying the remove-restore algorithm so it should handle any shape. One of the NOAA grids I used to test was non-rectangular.
