I have multibeam and single beam xyz points.
I am looking to do the exact same process as Patch over raster A with values from raster B where raster A values are nodata in GDAL as I want to infill the single beam NODATA values with values from the multibeam.
I have used Natural Neighbour as seen in pic below to rasterize my data.
I notice that step 1 is to create a nodata mask. How do I find my nodata value that I should be using? In the above example the person knew theirs was 255.
I use ArcGIS for viewing of the data.
