Hi,<br><br>Is there any documentation of the merits / purpose and intended future developments of the various XML layers such as GeoRSS, GML, KML etc?<br><br>They seem to be very similar and almost interchangable, and I'm finding this a bit confusing.
<br><br>For example, I'm using GeoRSS to draw markers, and KML to draw lines. However, this excellent GeoRSS Serialise example seems to be an edit / draw component for lines and polys: <a href="http://dev.openlayers.org/sandbox/ahocevar/sldRenderer/examples/georss-serialize.html">
http://dev.openlayers.org/sandbox/ahocevar/sldRenderer/examples/georss-serialize.html</a> Equally, KML boasts support for styles, although this is not implemented yet, and if we are accepting the Google definition, then KML should support both markers and lines / polys.
<br><br>Is there a twiki page for this or a good resource I could refer to? I'm considering developing this further and I'd like to make sure I'm doing the right thing before I start... Also if anyone if actively developing in this area I'd be very interested to discuss and see if I can help.
<br><br>My other point is about combined layers - I'd like to create a layer in the layerswitcher which shows markers and lines / polys (i.e. SVG I assume). Is it possible to make a combined layer or wrap two layers into one in some way?
<br><br>cheers, mike<br><br><br>
