I'm looking for an alternate way to undertake some processing.

Is there an ArcGIS Pro toolbox tool that can take an existing raster, use each cell (cell centroid?) to produce a new raster that contains the Count/Average/Sum/Etc of the cells within x distance?

So, lets say I had a raster where cells with houses present was a value 1, and everything else was a 0, I could produce a second raster with the input query being "for each cell give me the sum of all cells within 500m". The output is a new raster with the same cell boundaries (origin, width, etc - a snap raster in ESRI terms) where each cell is a count.

My current workflow would be to take the raster, convert it to points, buffer the points by 500m and produce individual polygons, ensure all datasets had a spatial index, summarize within / zonal statistics, join the resultant table back to the points, create the raster from points. It's horribly inefficient. The issue is I can't seem to work out if there's a tool to do it all within raster processing. If one exists - I do not know it's name and can't seem to find it.

  • Have a look at desktop.arcgis.com/en/arcmap/10.3/tools/spatial-analyst-toolbox/…. Your question is ambiguous in terms of raster representation that is used. Does each cell (value of 1) corresponds to one house unit or is it a result of polygon to raster conversion where each building is represented by lots of 1s? The outcome of this tool can differ what is represented by a cell.

  • Also, generate near table from desktop.arcgis.com/en/arcmap/10.3/analyze/commonly-used-tools/….

  • Thanks, although BERA already indicated what is most probably the best tool for the job. I think you have misunderstood the intent. Near describes what is near, not the aggregate of what is nearby when using an iteration over each cell of a raster (similar to a roving carat) by retaining the underlying structure of the raster. I also left out a specific case because the question was about a tool with particular capabilities, not how to approach a particular problem. I have a few scenarios to which the logic would apply, but didn't have the name of the tool at hand.

  • In fact what BERA said is same as what i said in my first comment. i also preferred to highlight some ambiguities in your question. Anyway, i am glad you have found an efficient solution.

Try Focal Statistics:

Calculates for each input cell location a statistic of the values within a specified neighborhood around it.
