This is a bit off the subject of Mapdex but if you are an ArcIMS user and would like to publish your imagery data with Google Maps, then check this out...

I updated Mapdex over the weekend and found a lot of GIS data for the Katrina diaster. 

There are 11 mapservices with "katrina" in the mapservice name.

There are 196 layers with "katrina" in the layer name.

USGS has put together a lot of images before and after for the area (Landsat, Ikonos, NOAA aerial photos, ASTER, Digital Globe).

For those of you curious about the logic behind the ArcIMS to Google Earth script (GE_KML.cfm), I have posted the code from that program.  The conversion script is written in ColdFusion.  It should be fairly straight forward to convert it to another server-side language.

Let me know if you have any quesitons.

Mapdex is fully integrated with Google Earth.

All mapservices that return a valid projection will have the ability to be added into Google Earth via network links. 

Here is the info:

• Will send the layer or service to Google Earth as a network link.
• Network links are available to individual layers or whole mapservices.  We are still working on scale issues.  If you don't see anything in GE you may need to zoom in to a smaller area.
• Will send you to the mapservice history page.  From here (located under service column) you can see how a mapservice has evolved over time (this is still a work in progress).
• Will send you to the mapservice information page.  This is the raw response for a mapservice from an ESRI-ArcIMS mapserver (WMS coming soon).

Let us know what works and what doesn't!

Cheers,

Jeremy

Search by Location:

We have moved the search by location tool to the main site.  You can search for interactive mapservices and geographic data layers by spatial location.  Take the following example:
