The mapping works as expected. You provide underlying data that corresponds to a latitude and longitude, and the visualization is created. The WMS functionality works very well if you would like to layer on some other type of geo-spatial information. My biggest complaint is in the geocoding. Spotfire won't recognize cities, states, or countries unless it is configured at the enterprise level on the server. At our company, it isn't configured, so I have to manually enter coordinates.
The mapping functionality continues to improve in Spotfire with additional features being added at each new release.
