I have a shapefile with 2M measurement points (each measurement point has a resolution of a 1/10). How can I aggregate points around each other if and create polygons out of it?
They do not have to match a grid, polygons should not overlap. In addition, I would like to reduce the resolution, e.g. aggregate all points around a 1/2 resolution.
Can I do this with QGIS or in PostGIS?
I have tried
convex hull, but it seems that the polygons overlapped. Also, some answers are referring to ArcGIS 10, which I do not have.
