For my current application, I need to simplify roads as much as possible. PostGIS provides the ST_Simplify function for this, and it works wonderfully. For obvious reasons, the closer I zoom into the layer, the simplifications that were fine when zoomed further out gradually become unacceptable.
Is there a way to make OpenLayers query a different (TMS) source based on the zoom level? If this can be done, I'll be able to tune the ST_Simplify tolerance parameter for each zoom level. -- Mak Kolybabi Programmer Telenium Inc. 204-957-2821
