Hi Jim, Yosri, Eric and others,
I have been following your conversation with interest. I am a Geomatician (GIS Specialist/Surveyor) who has worked extensively with ArcIMS (ESRI's Internet Map Server, which is what is used in the example Jim mentioned (see below)) and I am now delving into the world of SVG and loving it. I have begun by integrating SVG and ArcIMS to allow the user to draw on the image map returned by the spatial server (soon we will allow then to submit those shapes for storage). I have been pondering how to avoid the need for a map server when maps are data rich and multi layered. Or at least what options there are for effective feature selection and and basic queires to return SVG shapes are required. SVG seems ideal when the map can be sent in the first upload, but then they can not have high accuracy polygons (which increases the number of lines in the SVG file to a point where it can be much larger than your average image file). The need for an image base therefore seems unavoidable if there is a requirement for the map to be highly accurate...Any ideas?...WFS has potential.
I also believe that you are correct that there is a gap in the market where products like ArcView used to fit (it is now too expensive) and there are companies trying to fill that niche (www.manifold.net), but the desktop still seems to be the focus. I am more intersted in the possibilities for SVG based GIS for map viewing (and even data entry...)accessible via the internet to PDAs and cars, PCs etc without proprietory storage formats and ridiculous price tags. A picture is worth a thousand words and I am sure that every site that could have a map would put one on if they had a user friendly GIS type map creation tool, or a tool box of GIS tools for SVG creation, viewing and interaction (I will go and have a closer look at IziMap??). I am on the look out, but until then I will continue to work on the SVG data editing and input options and leave the complex background as an image (perhaps via Oracle 9i's MapViewer instead of ArcIMS - ArcIMS has not been easy to get up and running...grrr).
This Forum will be the first to know when I have a method I happy with.

What interests me is:
Have gone for an HTML + CSS + script + raster approach, yet are including
all the functionality of the majority of SVG approaches I've seen.
