Extending this thought a little. Is there a way to create a WMS service from this so that the WMS reads a csv file, automatically creates the polygons using the expression that Toto recommended, so that it (on the fly) creates the polygons from adding the WMS to a map so I can share with my co-workers so that we are all using the updated data (rather than having to share a shp file).
Long question, hoping for maybe an easy solution. Ryan VB Fiber On Thu, Nov 26, 2020 at 12:59 PM Ujaval Gandhi <uja...@spatialthoughts.com> wrote: > Totò - really great solution!
