How can hierarchical organisation be used to organise the map elements?
Sort through the components of the map to determine the relative importance of each one. Seek then, a visual solution that
will cast each component in a manner compatible with its hierarchical position.
Map objects that are most important are rendered with the greatest contrast to their surroundings. Less important elements
are placed lower in the hierarchy by reducing their edge contrasts.
Mapped objects and their relative importance assume a place in the hierarchy. Although identical objects may vary in relevance,
depending on the map on which they are placed.
The following illustration will explain to you how to achieve a hierarchical organisation of the map elements for a correct
presentation.
