Reconsider leisure=slipway rendering on linear ways #4108

Open jeisenbe opened 4 years ago

jeisenbe commented 4 years ago

Since PR #2825 we have rendered a SVG icon at the midpoint of leisure=slipway features which are mapped as linear ways.

While the Tag:leisure=slipway wiki page does not suggest this mapping technique, it has been used over 20% of the time (https://taginfo.openstreetmap.org/tags/?key=leisure&value=slipway)

If we are going to support this mapping, it would be better to render the way as a linear feature, not only as a POI icon.

Out of the ~8000 ways (vs 28,000 nodes), about 1000 are closed ways, and 7000 linea. Of these, less than a quarter have a highway= tag (almost all `highway=service).

So it might make sense to render these with a line, similar to a minor highway=service feature, since most mappers do not consider it necessary to add a highway tag.
