Sentinel-2: Resampling Spatial Resolution

[ABraun]

@Sent

what does the bilinear do exactly?

please have a look here

Radar Mosaic

I personally would also mosaic after I performed all other pre-processing steps. Only then you can assume maximum geometric accuracy. Resampling is needed when pixels of two adjacent scenes are not completely registered towards each other. One of the two rasters has then shifted to the pixel registration of the other. Nearest neighbor doesn’t change your values and assigns the pixel value of closest position [image] Bilinear uses averaging of adjacent pixels to calculate one new value at th…

Geocoding of the Polarimetric classification of Sentinel-1

What lveci suggests is that you use nearest neighbour in the resampling of the image’spixels, because it is the only method which doesn’t change the actual values.Geometric correction requires to put the pixels at a new location. At this step, resampling is involved because the pixels are no longer aligned within the original grid.
