Hi all-

Say you find a cool map service on Mapdex what do you do with it next?  First if you just want to view a simple map you can use either of the Mapdex map viewers.  The "View" link on the Search Results page will take you to a very simple map viewer.  If you would like to view multiple map services at the same time you can select the "add to map" button on the Search Results page and then select the "show on map" link.  This will open a Flash client that will allow you to view multiple map services from multiple servers at the same time.  The Flash viewer is a good example of a dynamic service based flash implementation.   (If you are interested in more about Flash and ArcIMS I invite you to download my colleague Asif Iqbal's Flash/ArcIMS example browser.  It is well documented and is more than enough to get you started on your way to rich, dynamic interactive map content.  http://drysdale.kgs.ku.edu/flashnew/  )

If you want more interaction with the map service I encourage you to view it in your GIS package.  For the ESRI map services you can easily view them in ArcMap (ArcGIS $$) or ArcExplorer (free).  Here is a good demo on integrating web data in ArcMap. 

The WMS services can be viewed in any number of packages (ESRI, Intergraph wmsviewer, and many others). 

Cheers,

Jeremy
