Hi,
The ListDatasets function works very well to run through a RasterCatalog. It took 3h58min to extract elevation from 1320 tiled DEMs...
Now, I would like to test the Walk function in order to see if the processing would be faster because the Data Access module is supposed to access data much faster according to ESRI documentation.
However,
_, _, rasters = next(arcpy.da.Walk(rasCatalog))
for raster in rasters:
arcpy.gp.ExtractValuesToPoints(fc, raster, fc_tmp)
did not work with workspace set a the Raster Catalog path...
And I have to admit that I am not familiar with the Data Access module syntax!
