With ArcGIS Explorer you can fuse data from multiple servers (OGC WMS, ArcGIS Server, and ArcIMS) and overlay local vector and raster data sets. The task-based interface allows fast visualization of massive 2D and 3D server-resident global terrain, raster and vector databases. The user interface exposes additional tasks for navigation, routing, geocoding/reverse geocoding.
David lets us know a little more about ArcGIS Explorer including that the beta will be out in a couple weeks. The biggest question I have so far is what ArcWeb services will be free? There is so much available for cost, but the free Public ArcWeb services choices are small. I can only hope that they will have good imagery by default, but at least support for most GIS server applications should allows others to fill the gap. I guess we’ll also see one of Sean Gillies’ favorite Web 1.0 applications integrated into ArcGIS Explorer, The Geography Network. Are there any plans to improve that service? What printing options do users have? Can we here more about the personalization and customization of ArcGIS Explorer (and I assume ArcGlobe server on the back-end)? What are the basic system requirements for ArcGIS Explorer (Google Earth runs wonderfully on my laptop, but ArcGlobe is a dog)? Does ESRI plan to have a community developed around ArcGIS Explorer (a huge issue as GE has a wonderful community and the current forums at ESRI are difficult to use)?
I’d love to see some screen shots or a video though of ArcGIS Explorer in action.
