Mapping GWR Output as Polygons

In many cases, you will be performing GWR on centroid geographies that were created from polygon geographies.  Although you can view your results by mapping the centroid-based output, you will often want to use point to polygon aggregation to convert this information back to polygons for visualization.    To do this, select the Aggregation method from the Methods menu, and enter the centroid geography, followed by the output of interest, in the two boxes that follow "Source dataset" at the top of the Task Manager window.  Then enter your polygon geography in the "Destination geography" box.   This will produce a dataset called "point to poly mean" (described here in the "Perform Aggregation" page) that you can add to a map.

Here is a comparison of maps using centroids vs. conversion back to county polygons.
