Is ErMapper's IWS helpful with MapServer?

[Stefano Parodi]

We use IWS and UMN MapServer together.
Here you can view an example:
http://ecozero.liguriainrete.it/CartoWebIWS/CwMain.asp?CwContext=http://ecozero.liguriainrete.it/MapServer/tmp/691109366context.xml&CwContextCatalogo=D:\Inetpub\Eco-internet\mapfiles\vincoli\VincoliContextCatalogo.xml

We use the ecw plug-in to display the raster data served by IWS, while the
vector data is from a WMS served by MapServer.
The ecw plug-in has the abiliy to query remote gis server that can serve
data in gif/png/jpeg format, so it's easy to integrate it in a OCG/WMS
architecture.

The advantage of the plug-in is the high grade of interactivity, like Frank
said, similar to google maps.
The next version of IWS seem different and apprently more similar to google
maps, using tiling images and without the use of a plug-in (it's all done in
 javascript) here an example:

As you can see it seem a google maps clone.

Stefano.
