-In the layer properties, you find below the menu tree, you can change the transparency as well as the drawing order of individual layers on the map. This are styling possibilities, while generating your own map, for the optimal layer view. Move the slider to change the transparency from 0 to 100%. Use the arrows on the right hand side to change the drawing order of the layers. Click on an upward arrow to bring the layer one level higher.\\ \\ \\ \\ \\ \\

 To select and inform you about a single polygon/municipality/area/map object, just click once on that object. The selected object will be coloured yellow and the parameter info box appears. There you can find all information you might be looking for. In the parameter info box the information of all activate layers on your cursor position will be listend. For the project results, the ecosystem service indicators, you'll find the demand, supply and flow values for the selected ecosystem service.\\ \\ \\

+  - The **expression box**: A user can define the expression here. AlpES layers can be dragged and dropped from the layer tree into this box, which will result in the 5-digit AlpES layer code with a '_' character prefix, pasted into the field.  Valid operators and functions can be found [[:wiki:webgis_calc_operators_functions|here]]
+  - The **clear text expression label** which shows the expression entered in (1) with clear text variable names indicating the layer label.
+  - The **validation button**: to check the expression syntax and populate the statistic fields below. Statistic fields below are provided for the user as a quick sanity check of the correctness of the expression. Only if the validation is successful, the **'Create Layer'** button (5) will become active.
+  - Messages to the user like a validation/error are being displayed here
+  - The **'Create Layer'** button to create the user layer and display it on the map. The layer will be inserted into the 'Layer properties' list of active layers on the navigation panel. Depending on the complexity of the formula and the classification method, layer creation can take up to ~10seconds.
+  - Expression **Import and Export** buttons: Expressions and corresponding styling can be saved to and imported from the local computer. This function allows sharing of expressions and user layers with other user. //Not yet implemented//.\\
