The special layer is designed to display singular information in the map like buildings or plants.
Different to the data layer, the value of any information stored on the special layer is a link to a special information.
For example, the value „1“ can identify a building on this grid. In order to display this information, you must link this value to a data set which defines the display color and the meaning to the information.

To edit the Special layer settings, open the Settings 2D dialog and press the Special Layer-Tab.
