Hi Nathan > 2. Can I assign a coordinate projection to SVG viewport. In other > words, after converting the GML data to SVG and viewing it in an SVG > viewer, can I display the lat/lon information of the GIS layer by > pointing mouse on the screen. If it is possibly then how?
Holger pointed to the message http://groups.yahoo.com/group/svg-developers/message/49753 and I agree with the steps described there. In the SVG viewport you won't have the information about the projection any more. SVG is based solely on rectangular coordinates and (as far as I know) knows nothing about the original projection. However you could transfer lat long values (decimal degrees) to SVG and display coordinates (using ECMSScript) but the user has to know that there will be some inaccuracies in the values displayed and in the portrayal itself. Intergraph's GeoMedia WebMap WMS server is able to export SVG. In this case metadata about the original projection are integrated in the SVG delevered by the server, and this inforamtion can be evaluated further by an application, for example in order to merge datasets.
