Editing City (section)

===Selection===

Due to limited space cities must be selected using some parameters. The primary goal of a cartographer is to provide the most information suitable for their audience. 

====Population====

Cities are often displayed if they exceed a certain threshold. This threshold may not be the present day population but instead the population during the time period the map is intended to depict.

====Proximity====

Maps may have to exclude population centers for readability. MapBox is an example of a map that uses multiple measures to dynamically choose the most relevant cities to display. They ensure that labels, regardless of their source, do not overlap <ref>{{Cite web |url=https://github.com/mapbox/mapbox-gl-native/wiki/Collision-Detection |title=Collision Detection · mapbox/mapbox-gl-native Wiki |website=github.com/mapbox/mapbox-gl-native |access-date=2024-11-09 |archive-date=2024-11-09 |archive-url=https://web.archive.org/web/20241109073018/https://github.com/mapbox/mapbox-gl-native/wiki/Collision-Detection |url-status=live}}</ref>. In practice this leads to a selection of cities that does not necessarily display ones with the largest populations.

====Historic Importance====

Sometimes cities may be chosen for their historic importance.
