I am currently dealing with a raster data with negative values but I want to remove them (aka I only want to keep values >=0). After that I need to map a csv file including thousands of poitns with longtitude/latitude information onto the raster data, and then I need to do a buffer of each point (buffer distance 2.5km). The buffer areas of each point will be overlapping since those points are really close to each other. The final result I want is to have a average buffer value corresponding to each data point, and then export them into a datafile (csv, etc.).
Any help is appreciated regarding removing negative values in raster data & averaging overlapping buffer values and exporting the data.
