[Geoserver-devel] Image Maps?

That'd probably work... does the SVG shape have to be the top layer?

There are a few of us looking into this question right now, but using
SVG and VML vector rendering.

(I'm using Mapbuilder, but others are looking into OpenLayers. We are
talking together, and have warm and fuzzy feelings about merging sometime).

In particular, we are rendering a vector feature using SVG, then
attaching a mouseEvent to the SVG shape. The event can then be processed
however you like:
Eg. Highlight the feature
Create a popup about the feature etc.

Ok,

I'll try that... basically, I'd like to be able to click on a particular

area

on the map and be able to drill into more detailed information on the
property that I am looking at.

Thanks,
Dan

You can have the mouse do a getFeature request (with a bounding box
parameter around the mouse by a few pixels) when the mouse stops, then
see if anything is underneath the mouse. You can then proceed from there.
Check out the "WMS Example" demo that comes with GeoServer, it does that.

Are there any capabilities to generate an HTML Image Map layer to provide
mouse-over capabilities?
