Map Layout Layer

With the OpenLayers javascript we can work out a nice map layout. We will only use OpenLayers to display the final HTML map and the embeded user interface for navigation, zooming and drawing. To have a general and flexible HTML map, we generate the HTML map code with a OpenLayers CGI. The script gets the basic layer as WMS object from the mapserver.

Map Application Wrapper Layer

To be capable the compute and display on the fly new geographical information, the OpenLayers CGI must call the Mapserver over a mapscript wrapper application. This script will compute the geographical information a set up the configuration for the request map.

New compute raster maps or shapes can be saved to the directory or the database.

Map Data Layer

The mapscript call finaly the Mapserver CGI. The mapserver CGI calls the raster maps the shapes from the directory or the the database.
