OpenStreetMap generally follows a control on the ground rule for mapping country borders. However, downstream maps often require showing different border configurations to their audiences. In the past, this typically necessitated map users to find or create alternate data sources for their borders to get around this limitation.
OSM data itself can now be directly used for the creation of dynamic map borders using relations that my former team and I created. These can be utilized to show any number of different map views once implemented in a map stack as we have done with Tilezen.
This talk will describe how we mapped these features, what they cover, and the sorts of border viewpoints they enable.
