I am looking for an equivalent tool to ArcGIS "collect events" (within the Spatial Statistics -> Utilities toolbox). I wish to aggregate coincident point data in a space where many points lie in exactly the same place making visualisation difficult.
For example, to go from:
thus providing a visual guide on density on points before proceeding to other forms of spatial analysis.
Is it possible to perform this on a different platform, preferably QGIS (or the associated PostGIS spatial db)?
