Like vector datasets, annotation datasets can have several data layers, each layer having different property values.
The common dataset properties are shown in the “Information” section. An additional section for each data layer shows the layer’s properties.
The properties for each part are:
Font: The font used to draw this part of the data. Clicking on this property opens a standard font selection dialog where the font style and color can be selected.
Enabled: If enabled, the part is visible. This property can be used to disable those parts of data that are not of particular interest.
Opacity: Makes annotations translucent. This will create smoother images and it can also be used to superimpose several layers of data.
Min. Altitude: The dataset vanishes if the camera is below this altitude (given in the selected units).
Max. Altitude: The dataset vanishes if the camera is above this altitude (given in the selected units).
