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

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)
