Publishing Images as Map

• Geo-Reference the image (e.g. with QGis: ​http://www.digital-geography.com/qgis-tutorial-teil-1-wie-georeferenziere-ich-eine-gescannte-karte-mit-qgis/)
  • for this to work one has to activate the GDAL-GeoReference? AddOn? (Addons->Manage Addons)
  • using WGS84 = EPSG:4326 should be a good choice
• Save this image as GeoTIFF
• Upload the GeoTIFF file to the server (for access see above)
• Publish the new layer ​http://docs.geoserver.org/stable/en/user/data/raster/geotiff.html
