Hi, I think you can find some examples for pan, zoom and measure at OpenLayers example page.
For changing map layers while zooming you could possible use maxResolution for your layer (or SLD). best regards Sarah ________________________________ Von: "[email protected]" <[email protected]> An: OpenLayers <[email protected]> Gesendet: Freitag, den 6.

I have some OpenLayers code that changes map layers as one zooms in and out. I've been looking through the GeoExt examples, and I can't find any of them that incorporates this functionality. They simple show how to turn on/off single layers. Ideally, I'd like to integrate a GeoExt zoomslider and toolbar (with pan, zoom, measure distance). Can someone share GeoExt code that does this? Thank you. Petrus
