I wrote the javascript demo/main.js including the following features :

  • set_name_property adapt the style's uses of "name:latin" to the data's name
  • switch_style_over select a style in the dropdown
  • add_geojson_playground, add_click_listener one big advantage of vector maps over raster is that you can directly click on a feature: this just shows the data from the tile and displays the geometry in magenta colour (in the playground layer)
  • enable_contours check on or off: draw an overlay of contours vector tiles
  • add_relief not currently available, but: show mountain shape data as 3d relief TODO add exaggeration, something like 2.5

The styles in styles/ are mostly not my work :

openstreetmap-vector

https://github.com/openmaptiles/openmaptiles/tree/master/style

which is an adaptation of the raster stylesheet

https://github.com/gravitystorm/openstreetmap-carto

And I added some adjustments:

  • show an orange_dot or purple_dot for restaurants/shops respectively at z14, like raster style
  • and hide names at those z14-z17. Also with more finegrained icon resolving for specific classes
  • correct colour of bus_stop_square, and change zoom-behaviour similarly to orange_dot and purple_dot
  • various additional sprites:
    • ref shield for class=trunk (road_trunk) in transportation_name
    • fountain in poi
    • duplicate diy to doityourself, inconsistent naming in the data...
  • mountain_peak text format when elevation is null: do not show stray "m"
  • manually setting class=pitch in layer landuse to be over class=residential, not under
  • tower_obervation and more specific towers, refined from viewpoint
  • class=information specificities like subclass=guidepost or subclass=board in poi
  • show pois more aggressively even at low zooms
  • miscellaneous zoom-stepping (newer syntax with ["step",["zoom"],"",15,["get","name"]])

The sprites are also incompatible with spritezero in some environments, regarding embedding href="data:text/base64,aaaaaa" binary data inline: for putting a png into an svg. This is the case for wetland_mangrove and similar. Using ffmpeg and then spritezero-png works, but involves generating sprites twice individually (for @2x.png and .png).

osm-bright

https://github.com/openmaptiles/osm-bright-gl-style

Basic starting style for omt-schema stylesheets, published by OpenMapTiles.

Has a horrible rank out-of-specification behaviour: filter based on 15 < rank < 25 !? This then hides almost all pois on high zoom

maptiler-basic

https://github.com/openmaptiles/maptiler-basic-gl-style

Basic starting style for omt-schema stylesheets, published by OpenMapTiles.

cyclo-bright

See cyclo-routes below

https://github.com/leonardehrenfried/cyclo-bright-gl-style

An addition to the osm-bright stylesheet

cyclo-routes

A subset of the above cyclo-bright, mostly the additions. Used as an overlay

contours

I did a raster to vector adaptation of https://wiki.openstreetmap.org/wiki/Contour_relief_maps_using_mapnik#The_PostGIS_approach
