[Qgis-user] scale dependent point clustering (for visualization only)

2011-05-27 Thread maning sambale
I'm looking for ways to create simple visualization of point clusters (in QGIS of course) similar to the openlayers cluster strategy: http://openlayers.org/dev/examples/strategy-cluster.html The purpose is simply for visualization and can be configured by map scale. -- cheers, maning

2011-05-27 Thread Andreas Neumann
No, the point displacement render is almost the opposite to clustering. It explodes feature that are stacked on top of each other so one can see that there are several features at the same place with potentially different symbolization. A cluster renderer would be a valuable addition to QGIS

[Qgis-user] Is there a vector equivalent of Build Virtual Raster?

2011-05-27 Thread Andrew Chapman
The Build Virtual Raster (Catalog) is great handling tiles in tiff format and makes for a much more responsive QGIS than trying to just add lots of rasters as individual layers. I also have an equivalent set of shapefiles, again covering tiled areas. Is their a vector equivalent to the BVR plugin?
