MapServer embedded GIS

GIS data are managed by the MapServer.

The server has three basic modes of operation:

  • with an interactive interface to manipulate and display map layers for dynamically generated maps;
  • embedded with object and model (output) display pages;
  • an administrative mode for the configuration of new mapsets.

For the interactive generation of maps, the user can select:

  • one background layer (usually opaque with full coverage);
  • one or more foreground layers (usually transparent or line features);
  • a size for the resulting map image;
  • layout specifications for a scale bar.

The resulting map is then displayed in the size specified.

The map generated is a composite of the layers selected:

on top of the (opaque) background map (a DEM in this example), one or more overlays consisting of line features and/or transparent layers can be placed and displayed.
In the embedded mode, a mapset associated with an object, scenario or location is shown as part of the object display.

The object defined the mapset, a reference point, and an area of interest defined as a radium around the reference point, as well as the size of the resulting map image.

The image can be any combination of

  • rasters such as satellite imagery or aerial photography;
  • pologones (opaque or transparent);
  • line features.

Every embedded map has an EDIT button in the upper right corner that leads to a configuration tool.

The user can chosse the reference point by either

  • clicking on the desired map location
  • specifying the exact coordinates
In parallel, the extent of the area of interest can be defined as a radius around the reference point in the center. Saving the new settings to the data base will lead to a redraw of the map with the new specifications.
