A new website has been added to the MapGuide Open Source Live Gallery, which includes three cool new sample applications and source code provided by Bob Bray, “The Autodesk MapGuide Guy”. These applications, including Dynamic Themes, Shareable Markups (redlining), and Ad Hoc Queries, show how powerful geospatial functions can be delivered through the web using MapGuide Open Source.
Dynamic Themes
Dynamic Themes allows the end user to apply a theme to an existing data set. For instance, a user can select the Parcels layer, choose the Net Value attribute, and create a colour ramp theming from yellow to red in six quantile breaks, with 30 percent transparency. Very cool.
Shareable Markups
Shareable Markups allow users to create their own shapes and text annotation on a map, and save them so that other users can see them too.
Ad Hoc Queries
Ad Hoc Queries allow users to query by attribute (for instance, all properties with value greater than 500,000) and by spatial filter (rectangle or polygon) and get back the matching set of features.
Together, these sample applications provide a framework that developers can extend to deliver robust geospatial functionality to their end users. They also show the depth and flexibility of the MapGuide APIs.
You can access this new set of applications and source code on the following website:

Hi,Jason. I’m GIS developer and I’ve worked at a Brazilian Autodesk Reseller and Consultant. I’ve developed gis systems since 3 years ago using Autodesk Map Guide 6.5 and Oracle spatial and Now I’m judging the MapGuide Enterprise. I’m find it much more slow than mapguide 6.5. I noticed this in that samples again. Do you agree with me ?

Are you running Enterprise SP1? There are considerable speed improvements when accessing Oracle data.
It’s hard to compare Enterprise against 6.5; they are completely different architectures with different viewing technology. I haven’t had a chance to run both on the same hardware with the same layers yet, so can’t comment one way or another.
I wouldn’t be surprised if Enterprise was slower. It’s still new technology, and it also has considerably more functionality than 6.5 did, which probably means that there is more overhead.
