Interstate rendering at low zoom levels #1
Comments
At low zoom levels, highway-intense locations like New York can be quite cluttered. Suggested zoom levels based on Slack discussions: |
To implement this properly, regular expression matching is required in the style layer. We would need to also deal with corner cases which use letters in interstate refs, for example:
For historical background, regex matching has been proposed for quite some time in mapbox-gl-js (mapbox/mapbox-gl-js#4089) but was never resolved. It has not been added to mapLibre. A plugin has been developed to add regex expressions to mapbox-gl-js (https://github.com/maphubs/mapbox-gl-regex-query) which may be helpful. This library has an attribution requirement which would need to be added. |
OpenMapTiles 3.13 will support interstate differentiation (but not 2/3 digit separation). |
Fixed in #72 |
At low zoom levels, the highway network should only show Interstate highways, and not other
highway=motorway
.At even lower zoom levels, the highway network should only show Interstate highways that end in a 0 or 5.
At the lowest zoom levels, shield rendering should be suppressed and the route network shown only.
Blocked by #9.
