[mapguide-users] MapGuide Open Source or MapServer

By using MapGuide OS I also think your going to see more development since
the promary goal is to push MapGuide Enterprise by Autodesk. Better support
and faster responses on feature aditions and bug fixes. Right now MapGuide
OS is like the beta test bed... once it proves itself stable Autodesk
releases a service pack for their Enterprise version.

As someone who has used both (and is actively working with both), I  
believe you will get the most mileage out of concentrating on the  
toolkit you will build the application with.  As it stands,  
MapGuide's application framework is not the most suitable for the  
kind of application you are describing.  It could easily be used to  
build this application, but the framework would necessitate a server- 
side solution involving redrawing at least one layer from the server  
for every update.  This is not necessarily a bad thing, but if you  
want a smooth client-side experience, using a javascript toolkit like  
OpenLayers (http://www.openlayers.org/) or ka-Map (http://ka- 
map.maptools.org/) will give you a google-like experience and allow  
you to plot and move client-side markers in real-time - something  
that the MapGuide application framework doesn't quite support yet.

OpenLayers and ka-Map are client APIs that use map tiles (MapGuide  
can do tiles too) to provide the map context, but provide a  
javascript API for plotting points/lines/polygons and creating  
interactive popups etc - just like google maps.  ka-Map has been  
built on top of MapServer directly and employs a reasonably popular  
tile caching mechanism that improves performance and map quality  
dramatically.  OpenLayers can use tiles from a wide variety of  
sources, including MapServer directly and from ka-Map's tile caching  
mechanism.  In addition, there is a new tile caching mechanism that  
is supported by OpenLayers that is built on a proposed standard for  
making WMS requests cacheable.  At this point, it would be difficult  
to say which is superior ... I think they are just different,  
although in the long term the standards-based approach would be more  
desirable to most people.

I have built several applications using ka-Map that do essentially  
what you are looking for.  I know that the same thing has been done  
with OpenLayers as well, although I haven't personally done it.

Disclaimer: I am the creator of ka-Map and am also a developer on the  
OpenLayers team ;)  In the future, the two apis will be coming closer  
together and, hopefully, merging.  My recommendation is that you  
should start with OpenLayers.
