The layers of a map contain different geographic and business information. The individual layers are laid over one another in the Web application and, in this way, make up the overall view of the map. You can show or hide individual layers and change the information contained in a map.
For each map layer, you must define how the data is displayed in this layer. Do this by selecting a map renderer .
To select a map renderer, use the parameter MAPLAYER_LIST under Map → Renderer.
The parameters that you can set for the map layer vary depending on the map renderer you choose. For more information on the various parameters, see:
