Maps should be as simple as possible – do not use satellite imaging if a simple line drawing would do. Maps should contain only as much cartographic or other information as required for accurate reading and understanding. Too much or irrelevant detail can slow down a reader’s comprehension or make the map difficult to decipher.
For example, not all maps require a coordinate system, but consider using an inset showing a larger region to give context to a specific location (eg inset the whole of Australia, with New South Wales shaded, on top of a more detailed map of New South Wales, or vice versa).
Tip. Consider how many landmarks are really required (eg capital cities, country or state borders, mountain ranges, major roads or infrastructure), and only include those that help readers comprehend the information.
The examples show the effect of reducing clutter and repositioning map elements for publication:
A map containing visual clutter
The same map with visual clutter cleared
