ArcGIS Explorer is a free rich client from ESRI that provides a gateway to geospatial data and analysis. Users may view both 2D and 3D mapping services from ArcGIS Server, ArcIMS, ArcGIS Online, local datasets, and standards based interfaces from the Open Geospatial Consortium (OGC) such as WMS and KML. Developers may also extend the capabilities of ArcGIS Explorer by developing custom tasks using .NET with the ArcGIS Explorer SDK.
The architecture diagram below illustrates how the participating software components are divided into logical layers and physical tiers. Please reference ESRI's GIS Dictionary to learn about specific software components and terminology.
