   * __**Find the Isoline Layer Minimum and Maximum**__
 Press "**Find Min/Max…**" to search for the minimum and maximum values on the isoline layer. When working with ENVI-met files, data inside of buildings (Special ID=1) are often on their initial value or not defined. You can tell LEONARDO to ignore those grids points when constructing isolines and search for the minimum and maximum value on the Isoline Layer.
   * __**Select a Reasonable Interval for Drawing the Isolines**__
 For example, if the first line (minimum line) is at 0.00, the next isolines will be 10.00, 20.00, 30.00 and so on until the maximum isoline is plotted.
   * __**Adjust Isolines close to Buildings**__
 If the option "**ignore grids with special=**" is selected, no isolines will be constructed towards grids with the selected ID (select "1" here for buildings in ENVI-met).
-The following two pictures illustrate this concept: In the upper figure, the "ignore grids" option is not used. LEONARDO tries to build isolines including the undefined (random or initial) values below the buildings.  This looks messy, because a lot of isolines are constructed around the undefined data. The figure below shows the same data set but with the "ignore grids" function enabled and ignoring data below specials=1. This looks much better.

+The style and the color of the isolines can be selected in various ways.

+Isolines are organized in 3 classes: positive, negative and zero isolines. \\

+For each of the 3 types, you can select the **line width**, the **line color** and the **line style**. \\ (Different line styles only work with 1 pt width at the moment). \\

 The last line style is "empty" which means that the lines are not drawn.
+You can also color the isolines depending on their value. Check the option "**Use color settings from Data Layer-Key**" to enable this function. In this case, the settings from the data key (number of classes, number of colors, class values) are used to determinate, in which color the isoline is drawn. Note: Different to the vector layer, where the values on the data layer are used to identify the color of the vector, the isoline layer values will be used here to select the color.

-®Control the isoline text labels
-LEONARDO provides a very simple mechanism for labeling the isolines.
-Use the "Show labels at isolines" option to show or hide the labels.
-The associated "Label Distance in grids" is an indicative value how many labels are placed along the isolines. However, as mentioned before, the isolines are drawn grid-by-grid, not as a line object. Therefore LEONARDO cannot exactly determinate when the last label on an isoline was drawn. Low values for label distance will produce many labels, high values will produce few labels. You should test, which value fits your needs and data best.

-"Unit name" is the data unit name written behind the label value, "Nr of digits" tells LEONARDO how many decimal digits should be generated.

+The "**Restrict Labels**" option is another way to control the design of the map. \\
 Selecting "medium smooth segments" will prevent very curvy isolines of being labelled, "smooth segments" will restrict labels to very smooth isoline sections. Finally "no restriction" will put labels everywhere where they should appear following the label distance value.
