Google Maps and Yahoo Maps (and associated APIs) would probably represent the current state of the art in what's achievable with pure web standards right now. I suspect for many projects these systems would more than suffice (and save a fortune in licensing fees). Both systems allow simple shapes (lines, polylines etc) to be overlaid on the maps. Also images can be imported and overlaid. A good example of what you can achieve with these APIs is this site: http://www.runningmap.com/
Going forward (if staying with official web standards) SVG (Scalar Vector Graphics) might offer ways of achieving better editing capability. Disappointingly Microsoft decided not to support SVG in IE 7. I'm not sure if they will do so in future (I suspect corporate politics determine the feature list, and not any technical or customer concerns). It's an unfortunate situation... whereas "web 2.0" has benefited by the relative stability in the browser environment over the past few years, the downside is there has been little real progress in the underlying technology. Douglas Crockford (Yahoo) has a good talk about the sorry state of browser technology in his talk "The State of Ajax" which should be downloadable at http://yuiblog.com/ [for some reason it's not there right now -- I assume that's a temporary glitch].
