I need a map that can represent density estimates. The estimates are tied to points, but are for 1 hectare (100m*100m) areas of which the point is the centre. Each point has at least one, but usually 3 or 4 other points that fall within its 1 ha area. I would like all of the overlapping areas to show up as means of the relevant estimates.
In other words I would like the density estimate tied to the point to be applied across 1 ha, and for the estimate to be averaged anywhere that it intersects the area of another estimate.
Is this possible?
Preferably I would be able to do this in QGIS, but am also open to instruction in ArcGIS.
So far, I have tried a point density map, and a kernal density map in arcgis, but the values were not averages of the estimated densities tied to each point.
I also tried converting the points to square polygons using the buffer tool and then the feature envelope to polygon tool in ArcGIS, which allowed me to make the points into 1 ha boxes. I was unsure what to do after that.
My question is also somewhat similar to this one from two years ago, which never received an answer: http://gis.stackexchange.com/questions/87429/how-to-simulate-venn-diagram-of-buffers-using-qgis
