A user accesses the information on the SVS Image Server in one of three ways:
- with a standard web browser, which will allow the user to browse the individual products,
- with more advanced software that allows viewing the products on an interactive 3D Earth globe,
- with any software application that supports the
Web Map Service (WMS) protocol.
To browse the individual products, go to the Available Animation List.
To view the products in 3D on a Windows-based PC, download NASA's
WorldWind software. This tutorial is for developers who wish to create WMS-based software to access
the products on the SVS Image server. The tutorial is both an introduction to the WMS protocols and a
description of the specific ways that this server implements those protocols.
Using the WMS protocols, the client application asks the server for a "table of contents" and
then for specific images, e.g.,
PC Client - "What animations and images do you have?"
SVS Image Server - "I have
+ Global Ozone during the 2003 Ozone Hole
+ Global Atmospheric Carbon Monoxide in 2000
+ Cold Water Trails from Hurricanes Fabian and Isabel
+ African Fires during 2002
PC Client - "Give me 'African Fires during 2002'"
SVS Image Server - "Here are the images:
, , , etc."
