Department of Advanced Computing
SARA (Search And Rescue Application)
• Decision support tool for the Joint Rescue Coordination Centres in Norway
• Operative since 2000• Primary function is to aggregate and present all
relevant information about real and potential emergency incidents, including location-based information on electronic maps
• First SW to present results from LeeWay simulations
Department of Advanced Computing
What is web mapping (WMS)
• Standard for transferring map images over Internet• Standardized by Open Gis Consortium (OGC)
– First version 1.0.0, 2000-04-19– Current version 1.3, 2005-08-02 (also ISO/DIS 19128)
• Uses HTTP Get and parameters as ”query string”• Transfers the map as image
– e.g. As PNG, JPEG, GIF, SVG
• Three different requests:– GetCapabilities (What is available)– GetMap (Map image)– GetFeatureInfo (Info about a position on the map)
• Standard handling of coordinate systems (CRS)• Handles also time and elevation

MetOc server
• Developed for the Norwegian Defence Research Establishment in collaboration with Met.no
• WMS server supports grid data (GRIB), particle simulation results (oil drift, ship drift), observations (scatterometer, altimeter)
• Plot time series profiles and cross-sections• Exports and imports GRIB data to and from other
servers• Supplies applications with XML data services
(profiles, time series, cross section)
Department of Advanced Computing
AIS server
• Handles multiple AIS sources• Web browser as client (multiple browser support)• Shows traffic info as a map or a table• User defined filters (Norwegian pilots, tankers
north of 62)• Multiple custom defined background maps • Support WMS foreground maps• Exports data directly to other applications• Integrated database for historic data• “Smart links” to other web applications
