  1. MapServer e-technology in a few words ... www.mersea.eu.orgwebmaster@mersea.eu.org

  2. MapServer Technology(http://mapserver.gis.umn.edu/) • An online Geographic Information System • Since 1994, open source middleware, developped by University of Minnesota with support from NASA • (Map Server) Added values • Process vector data (ESRI shapefiles, PostGIS, ESRI ArcSDE and others via OGR ) • Process raster data (TIFF/GeoTIFF, EPPL7 and others via GDAL) • Connectable to Opendap (now process numerical data and access them on Internet) • Quadtree spatial indexing for shapefiles • Enables inter-operability / inter-activity functionalities • Select the product of interest • Sub-setting capabilities • Overlay capabilities • On-the-fly configuration via URLs • On-the-fly projection • Feature selection by item/value, point, area or another feature • Fully customizable, template driven output, map element automation (scalebar, reference map, and legend) • ‘Mosaic/Puzzle’ presentation so as to take account of the better accuracy per area • Auxillary data • Ports, Rivers, Currents (vector) • Bottom topography, Bathymetry, Climatology (raster) • Argos data (vector)

  3. MapServer: 4D data into a 2D mapping tool

  4. wind (AVISO) 20/08/2004 grid: 1/3° scale: 0 to 16 m/s SST (AVHRRR) 11/08/2004 grid: 0.04° scale: 0 to 30° MSLA (DUACS) 10/07/2004 grid: 1/3° scale: -50 to 50 cm Ocean color / chlorophyl (MODIS) 11/08/2004 grid: 0.04° scale: -80 to 100 xx E-techno Added Value: quick test with a Map Server

  5. Framework Added Value (quick test with a Map Server) SST (AVHRRR) 11/08/2004 grid: 0.04° scale: 0 to 30°C Ocean color / chlorophyl (MODIS) 11/08/2004 grid: 0.04° scale: -80 to 100 Temperature (MERCATOR) 01/01/2004 grid: 1/8° scale: 0 to 30°C Salinity (MERCATOR) 01/01/2004 grid: 1/8° scale: 25 to 40 psu

  6. Use example: Seal => New in situ data ? or animal behaviour in an ocean environment ? 2 day interval To= 20 march 2004 (a good diverabout 1 hour length) North Atlantic Drift Depth (m) Temperature oC Distance (km)
