Dataset Legend Editor

Define and save the dataset legend, the presentation of the spatial objects using the Legend Editor.

Concept

Spatial resources (vector, raster, image) do not include legend or layout information. Orbit stores the “layout component” in a separated Orbit Legend File (*.olg).
By default Orbit will search and use automatically the .olg file in the same folder and having the same name as the spatial resource file. We do advise this default naming, but this is not mandatory. For example it can be useful to have different presentations for one dataset.

Legend File

One dataset has one legend file, but each dataset model has its own legend component to be set separately.
The legend component's graphical parameters depend the dataset model spatial object type (point, line, area, image or raster).


Legend Components

Basic Appearance = one presentation for all objects within the dataset model.
Classification = different presentation of objects in one dataset based on their attribute component.

The Basic Appearance will be overruled by the Classification if set.
All graphical parameters that are not defined by a Classification will be set through the Basic Appearance.
