The results should be published into https://github.com/protomaps/basemaps-assets repo, but linked to style changes in this main basemaps repo.
Because many poi
layer kind values have the same effective min_zoom
, Tilezen uses an additional collision_rank to add a deterministic order for label collisions. Using PlaneTiler we could use the collision rank but reimplement this as a tile based ordering honored by MapLibre (the collision rank property could be dropped once the tile feature ordering is achieved).
Initial list for tileset v3.6:
pmap:kind
: hospital
, hotel
, library
, park
, playground
, police
, post_office
, school
, stadium
, supermarket
, university
, national_park
, forest
, station
, restaurant
, cafe
, fast_food
, zoo
, attraction
, fire_station
, bank
, college
, golf_course
, military
special icon cases (pmap:kind_detail
) with fallback:
restaurant
: all fork+knife for now
place_of_worship
: christian
, muslim
, buddhist
, hindu
, shinto
, jewish
, taoist
, sikh
sport
: soccer
, tennis
, basketball
, baseball
, swimming
, equestrian
, golf
townspots, generic shields
todo: airports? different station classes??
Yes, airport
would be great addition to the basic set :)
I'm going to merge styles v3.0.0 with the minimum possible sprites (townspot
only) and then make more additions in minor versions.
Perhaps for later, I’d suggest museum
as a nice basic one.
Looking forward to POI sprites and labels on the map! Those really help bring a map together.
Description
Adding a basic spritesheet (PNG and JSON config, referenced in the JSON style) would allow town icons and text to pair and collide together avoiding orphan townspot circle symbolizers on the map in the
places
layer. This would also allow for road shields in theroads
layer.A more advanced option is to add more sprites for the
pois
layer related to the dozens (and even hundreds) of existing and potential kind values there.Unlike fonts, icons need to be tied with a map style – if a map style is black and white the icons should also be black and white, if a map style is color than color icons - and tileset major version to allow for additions to kind values.
