  3. GIS Data Data Views Satellite Time Map Vector Cursor Scatter Text XDim Data SQL Table Web Page OLAP Cube Text Data Text Data Distributed Data Browser Architecture(Needs your input, many of the details..) Data of multiple sources and types (map, time) are accessed Data are rendered by linked Data Views (map, time..) OpenGIS Services General Approach: Ride the Internet wave to the max: OpenGis, .NET, XML… .NET Services Session Manager The hart of our system is the Session Manager (Broker?) The Connections, Data Access, Views and the Cursor are managed. Cursor Manager Connect Manager HTTP Services View Manager DataGet Manager
