*I am fairly new to working with raster data in ArcMap. *
I have a raster dataset like in the picture I have uploaded, and you can assume that each individual pixel of the raster has a value which is given in red. What I want to do is aggregate the pixel cells up to the resolution that I want such that I can add the values associated with the individual pixels. In the picture, the original 4x4 raster would be aggregated up into a 2x2 raster, however what I am not sure about is how you could tell ArcMap to add together the cells that you want to have been added.
One possible solution I am thinking of (but haven't had an opportunity to try) is to generate a 2x2 fishnet over the area and try to aggregate the pixels that are contained within the fishnet. I am not sure if there is a simpler way to go about this though.
