Import building footprints. Use properties to determine building height and style.
When you import building footprint data, you can map corresponding properties like roof slope and roof material. Use facade material for the rule style.
If you do not have an exact match for a property, you can use an expression to create that match. In this example, determine the height of buildings based on an expression that uses the properties Floors and Floor_Hght.
For example, map properties from your original data store to the Roof Slope and Roof Material properties.
Click the Expression Editor icon in the Rule Style field.
Create the expression Floors * Floor_Hght and click OK.
