I have one high resolution raster 1m with dimensions 12671x12756 and other a Sentinel 2A raster with dimensions 1606x1596. Both of them are of same extent but the high-res tiles has some nans and I want to transfer them to the low res tile, basically, make the same areas 0s as well.

I tried using numpy but there are lot of dimensions mismatch errors, what else can I try here?

  • Does the nans have some value which can be selected using raster calculator? Maybe somthing like this is possible: gis.stackexchange.com/questions/81640/… But set the nans as your 1m raster instead of 0

Resample your high resolution 1m raster to match the resolution of the lower resolution tile. That should eliminate the dimension mismatch errors and allow the NaN data to be transferred to the lower resolution image.
