Spatial Analysis and the Geoweb
summary
A cloud GIS called ArcGIS Online exposes map services, tiled base maps and APIs so developers mash up authoritative imagery, USGS/topographic tiles and OpenStreetMap layers, with iPhone app and Silverlight clients that already load live services. The system lists about 50,000 servers and registers roughly 300,000 user organizations, lets users combine map services, save maps and publish apps, and shows working examples—crime maps, animated Chile earthquake layers, and a citizen pothole report workflow that posts into municipal GIS.
