Mashup Capabilities
The Map Viewer let users overlay or mashup data layers from different map servers, which may be hosted by different organizations using different protocols (e.g., ArcIMS, WMS). For example, by searching the catalog, users could discover three different map services, hosted by the Nature Conservancy, Conservation International, and World Wildlife Fund, delineating conservation priority areas. Then, with a click, these live maps can be overlaid together in the Map Viewer along with a satellite image backdrop from NASA. Users could then zoom and pan to their area of interest, turn layers on and off, adjust transparencies, and save that map view to a URL, which they can e-mail to their colleagues to show how various priority maps compare. When their colleagues click the link, exactly the same map view opens, allowing them to work with the live map, perhaps adding map services or posting the link to the map view on their Web site.

Famous quotes containing the word capabilities:
“I maintain that I have been a Negro three times—a Negro baby, a Negro girl and a Negro woman. Still, if you have received no clear cut impression of what the Negro in America is like, then you are in the same place with me. There is no The Negro here. Our lives are so diversified, internal attitudes so varied, appearances and capabilities so different, that there is no possible classification so catholic that it will cover us all, except My people! My people!”
—Zora Neale Hurston (1891–1960)
