Migration Guide for v1.0 Mapzen Vector Tiles

This is a cheat sheet summarizing the v1.0 Mapzen Vector Tiles CHANGLELOG's major breaking changes that we used to update Mapzen house styles.

  • Topic
    • example Tangram scene file YAML old > new

===

  • new tile url sources:

    • https://vector.mapzen.com/osm/all/{z}/{x}/{y}.mvt > https://tile.mapzen.com/mapzen/vector/v1/all/{z}/{x}/{y}.mvt
  • every layer: sort_key property renamed to sort_rank

    • feature.sort_key > feature.sort_rank
  • every layer: boolean values yes > true (for everything except oneway)

    • water layer:
      • boundary: yes > boundary: true
    • roads layer:
      • is_tunnel: yes > is_tunnel: true
    • roads layer:
      • is_bridge: yes > is_bridge: true
    • roads layer:
      • is_link: yes > is_link: true
    • boundaries layer:
      • maritime_boundary: yes > maritime_boundary: true
    • building, earth, landuse, and water layers:
      • label_position: yes > label_position: true
  • roads layer: highway property renamed to kind_detail

    • highway: [trunk, primary] > kind_detail: [trunk, primary]
    • highway: secondary > kind_detail: secondary
    • highway: [tertiary, tertiary_link] > kind_detail: [tertiary, tertiary_link]
    • highway: service > kind_detail: service
    • highway: [steps, track] > kind_detail: [steps, track]
    • highway: pedestrian > kind_detail: pedestrian
    • highway: track > kind_detail: track
    • highway: steps > kind_detail: steps
  • roads layer

    • Natural Earth

      natural_earth_roads:
          * filter:
          *   * - $zoom: { min: 5, max: 8 }
          * major_road:
          *   * filter: { kind: major_road }
          * minor_road:
          *   * filter: { kind: minor_road }
      
    • for OSM roads in mid and high zooms, optionally:

      osm_roads:
         filter:
             - $zoom: { min: 8 }
      
  • roads layer: man_made > kind_detail

    • man_made: [pier] > kind_detail: [pier]
  • roads layer: aeroway > kind_detail

    • aeroway: taxiway > kind_detail: taxiway
  • roads layer: aerialway > kind_detail

    • aerialway: [gondola, cable_car] > kind_detail: [gondola, cable_car]
  • boundaries layer: admin_level > kind_detail

    • admin_level: 2 > kind_detail: 2
  • pois layer: sport > kind_detail

    • feature.sport > feature.kind_detail
    • sport: basketball > kind_detail: basketball
  • places layer: type > kind

    • type: country > kind: country
  • buildings layer: building area are funky at mid-zooms now because of merging

    • use new scale_rank to filter instead of area at zoom 13 and 14

    • zoom 13

      - { $zoom: [13], area: { min: 50000 } }
      - { $zoom: [13], height: { min: 250 } }
      - { $zoom: [13], volume: { min: 200000 } }
      

      to

      - { $zoom: [13], scale_rank: [1,2] }
      
    • zoom 14

      - { $zoom: [14], area: { min: 5000 } }
      - { $zoom: [14], height: { min: 190 } }
      - { $zoom: [14], volume: { min: 150000 } }
      

      to

      - { $zoom: [14], scale_rank: [1,2,3] }
      
    • Where scale_rank is defined in this table:

        area,height,volume,landuse_kind,scale_rank
        >=100000,*,*,*,1
        *,>=250,*,*,1
        *,*,>=300000,*,1
        >=20000,*,*,*,2
        >=5000,*,*,+,2
        *,>=150,*,*,2
        *,*,>=150000,*,2
        >=5000,*,*,*,3
        >=3000,*,*,+,3
        *,>=100,*,*,3
        *,*,>=100000,*,3
        >=1000,*,*,*,4
        >=500,*,*,+,4
        *,*,>=50000,*,4
        +,*,*,*,5
      
  • buildings layer: kind properties are now kind_detail

    • kind: [university, college, school, kindergarten] > kind_detail: [university, college, school, kindergarten]
    • kind values in buildings are now building or building_part (in addition to address & etc)
  • places layer: scalerank > min_zoom

    • you can generally remove the scalerank filters completely from low zooms, as well as source filters.
    • at mid zooms you can still mix and match Natural Earth and OpenStreetMap features to "backfill" low or no pop places.
    • scalerank: [0] > min_zoom: [2]
    • scalerank: [1] > min_zoom: [3]
    • scalerank: [2] > min_zoom: [4]
    • scalerank: [3] > min_zoom: [5]
    • scalerank: [4] > min_zoom: [5]
    • scalerank: [5] > min_zoom: [6]
    • scalerank: [6] > min_zoom: [6]
    • scalerank: [7] > min_zoom: [7]
    • scalerank: [8] > min_zoom: [9]
    • scalerank: [9] > min_zoom: [9]
    • scalerank: [10] > min_zoom: [10]
  • boundaries layer: scalerank > min_zoom

    • scalerank: [0] > min_zoom: [7] (yeah, right! this was to fix bad data, see Hungry)
    • scalerank: [1] > min_zoom: [2]
    • scalerank: [2] > min_zoom: [2]
    • scalerank: [3] > min_zoom: [3]
    • scalerank: [4] > min_zoom: [5]
    • scalerank: [5] > min_zoom: [5.5]
    • scalerank: [6] > min_zoom: [6]
    • scalerank: [7] > min_zoom: [6.7]
    • scalerank: [8] > min_zoom: [6.8]
    • scalerank: [9] > min_zoom: [7]
    • filter: { scalerank: [0,3,4,5,6,7,8,9,10], $zoom: { max: 8 } } > filter: { not: { min_zoom: [1,2] }, $zoom: { max: 8 } }
  • landuse layer (and pois that have areas from landuse polygons:

    • remove all the area filters
    • except:
      • kind: [garden, allotments]
      • kind: [police, fire_station, substation, plant, wastewater_plant, water_works]
      • kind: [cafe, restaurant, nursing_home]
      • kind: [parking, pedestrian, common, pitch, place_of_worship, playground, school, nursing_home]
  • place layer: kind values

    • kind: [city, town] > kind: locality
    • kind: [village] > kind_detail: [village]
    • kind: [hamlet] > kind_detail: [hamlet]
  • place layer: capital (and yes)

    • capital: yes > country_capital: true
    • state_capital: yes > `region_capital: true
  • place and boundaries layers: region

    • kind: [state] > kind: [region]
  • landuse layer: forest

    • some values are now natural_forest
    • but many values are still forest
  • landuse layer: park

    • some values are now natural_park
    • but many values are still park
  • landuse layer: wood

    • some values are now natural_wood
    • but many values are still work
  • earth layer: continent labels

    • If you haven't updated for several versions, continent labels moved to the earth layer (from places layer)
  • water layer: ocean and sea labels

    • If you haven't updated for several versions, ocean and sea labels moved to the water layer (from places layer)
