Latest changes• Improved image browsing included
Animated GIF generation– browsing interface (to search through stored
images such as e.g. TEC Maps
– Select start date and end date from available images to compare 2 images or to generate an animation
• Improved web service allows platform independent, automated access to space weather data.– Applications (both web and desktop) can access the
data stored in the SWENET space weather database.
