MapServer e-technology in a few words ...

MapServer Technology(http://mapserver.gis.umn.edu/)

An online Geographic Information SystemSince 1994, open source middleware, developped by University of Minnesota with support from NASA

(Map Server) Added valuesProcess 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 shapefilesEnables inter-operability / inter-activity functionalities

Select the product of interest Sub-setting capabilitiesOverlay capabilitiesOn-the-fly configuration via URLs On-the-fly projectionFeature 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 dataPorts, Rivers, Currents (vector)Bottom topography, Bathymetry, Climatology (raster)Argos data (vector)
