Highly Interactive Web Maps
A dynamic, interactive web map is the centerpiece of a comprehensive geospatial work environment. Not only for retrieval and display of data, but also a platform for data creation and editing. And access to all the analytical power of the spatial database.
Whether you are integrating your data environment with one of the commercial mapping APIs or with open source tools such as Mapserver and OpenLayers, your map becomes your workspace. There is a wide array of display, navigation, and editing capabilities that you can exploit to accelerate your work.
In effect, you have desktop GIS functionality in the web browser.
