v1.9.0

  • Release date: 2023-03-10.

  • Requires: tileserver v2.2.0 and tilequeue v2.5.0 and rawr_tiles v1.1.0 and coanacatl v1.0.0.

  • Credits: @travisgrigsby, @jeffdefacto, @peitili, @iandees, and @nvkelso

    ENHANCEMENTS

    • Significant performance improvements to reduce p99 file sizes globally (-45%) at all zooms to under 200 kb, with some improvements for low-zoom p50 sizes. Changes include: geometry simplification at low zooms, pushing some features like unclassified roads to the next zoom, dropping names on short lines and dropping other properties at mid-zooms to also allow more aggressive merges to multi-lines and multi-polygons, and more sophisticated handling of max zoom and overzoom tiles for buildings and addresses. Further reductions can be achieved by configuring Tapalcatl to selectively drop layers and name translations (eg to drop earth and transit layers or only keep English and Urdu names) depending on your business needs. tilezen-v1d9-versus-v1d6-size-zooms (Above) Chart shows sizes in kilobytes, based on commonly requested top 100,000 tiles at 512 pixel zooms. NOTE: all other zooms in this document use nominal 256 pixel zooms, offset by 1.
    • Internationalization is now feature complete by extending disputed boundary point-of-view handling fully into mid- and high-zooms with extensive paired data edits upstream in OpenStreetMap, using Natural Earth as a sanity check for country names, and consideration of common and less common edge cases, including Taiwan and Somaliland.
    • MapLibre support with buffered tiles and connivence properties like pre-calculating shield text length allow Tilezen tiles to more easily be styled in MapLibre and MapboxGL, thus extending support beyond Tangram.
    • boundaries: Add disputed boundary line point-of-view (POV) for mid- and high-zoom features sourced from OpenStreetMap (OSM), including extensive upstream editing in OSM to match Natural Earth's low-zoom disputed area modeling in earlier releases. New unrecognized_dispute kind and disputed_by property. (Issue #1901)
    • boundaries: Add missing Cyprus line-of-control (aka "green line") as it has custom admin_level tagging. (Issue #1898)
    • boundaries: Add Ukraine point-of-view for disputed boundaries. (Issue #1911)
    • boundaries: Add disputed boundary in South China Sea scoped to China's point-of-view (POV). (Issue #1983)
    • boundaries: Mark some Natural Earth low-zoom boundaries as default unrecognized, including for Abkhazia, Donbass, Nagorno-Karabakh, Northern Cyprus, Somaliland, South Ossetia, and Transnistria. (Pull request #2072)
    • buildings: Add additional non-OpenStreetMap buildings from the Microsoft sidecar in Daylight distribution.

    • places: Add recasted Australia "suburbs" from OpenStreetMap as locality features to match local expectations. (Pull request #2070)
    • places: Improve continuity between Natural Earth and OpenStreetMap (OSM) locality features and their min_zoom grading. (Issue #2020)
    • places: Join OpenStreetMap locality features with Natural Earth (NE), and prefers NE names to improve consistency across the zoom transitions. (Pull request #2088)
    • places: Join OpenStreetMap locality features with Natural Earth (NE), and prefers NE population to calculate population_rank for label grading. (Issue #2048)
    • places: Backfill population estimates for OpenStreetMap-sourced locality features. (Issue #1992)
    • places: Cull locality and neighbourhood features based on grid to right size tile payload to rendered features. (Issue #1999) and issue #2040)

    • roads: Calculate new shield_text_length property to ease styling of road shields in MapboxGL-based map styles. (Issue #1979)
    • water: Add kind_detail for polygon features, with values including: basin, canal, ditch, drain, lake, river, and stream. (Pull request #2047)
    • water: Mark water polygon feature as kind_detail = lake when upstream OpenStreetMap value is lagoon, oxbow, pond, reservoir, or wastewater. (Pull request #2047)
    • water: Add optional layer property for complicated over-under rendering situations, with adjusted sort_rank for some features. (Issue #1910)
    • all layers: Switch to Daylight distribution for ingesting OpenStreetMap planet files, including building and admin sidecars. WARNING: Some OSM feature IDs may be re-numbered. (Pull request #2085)

    • all layers: Add MVT buffer support to enable MapboxGL to render stroked lines at tile boundaries without missing triangles (eg for road casings). Tilequeue #401
    • all layers: Vary the MVT tile extent so 8192 is only used on max_zoom (and 4096 earlier) to optimize file size while preserving overzooming. (Issue #1985)
    • all layers: Are now MVT v2 spec compliant, via related changes in Tilezen's mapbox-vector-tile v2.0.0 release.

    BUG FIXES

    • boundaries: Show all missing disputed lines for point-of-view (POV) in low-zooms (remove min_zoom filter). (Issue #1970)

    • boundaries: Drop additional ID and name properties at mid-zooms and merge lines at high-zooms. (Issue #2007)
    • boundaries: Revert poor tolerance config change from earlier release, this improves visual look for 512-pixel tiles in MapboxGL-based styles. (Issue #1980)
    • boundaries: Fix some incorrectly marked maritime boundaries with new buffered land masking file. (Pull request #2073)
    • buildings: Add root_id = id to simplify MapboxGL-based styles. (Issue #2092)

Drop more bus, walking, and bicycle network properties at low- and mid-zooms. Drop general road shield properties at earlier zooms by kind. Drop other properties at earlier zooms. Selectively drop landuse_kind from mid-zooms by kind. Shift unclassified roads min_zoom back to 12 from 11 as that's more common outside the USA than previously explored and negatively affected tile size. (Issue #2008)
    • roads: Remove additional low- and mid-zoom ferry and aeroway properties to enable more line merging. (Issue #2017, issue #2018, and pull request #2056)
    • roads: Revert poor tolerance config change from earlier release, this improves visual look for 512-pixel tiles in MapboxGL-based styles. (Issue #1980)

v1.8.0

  • Release date: 2019-06-27.

  • Requires: tileserver v2.2.0 and tilequeue v2.4.0 and rawr_tiles v1.1.0 and coanacatl v1.0.0.

    ENHANCEMENTS

    • boundaries: Add more kind:* point-of-view (POV) from Natural Earth for low zooms for disputed boundary lines, expanding on the v1.7 effort to also include region boundary disputes. (Issue #1840)
      • To handle disagreements about the location of borders, the kind may be prefixed with unrecognized_, e.g: unrecognized_country (was unrecognized in v1.7), unrecognized_macroregion, unrecognized_region, unrecognized_county for differing viewpoints (see kind:xx below).
      • kind:xx: alternate kind according to the viewpoint of country code xx. If you want to show features according to a particular viewpoint, then use kind:xx if it exists and fall back to kind if not. The range of values is the same as for kind. Note that the viewpoints are either lower-case ISO 3166-1 alpha-2 codes or the pseudo-code iso.
    • boundaries: Add OSM alternate viewpoints for country, region, and counties boundaries. (Issue #1810)
      • We track two kinds of features from OSM for indicating disputes:
        1. claims, which have boundary=claim, claimed_by=*, admin_level=* tags. These indicate borders which aren't generally recognized, but should appear in the viewpoint of the claimed_by= value. additionally, extra viewpoints which don't make a claim for themselves but still want the claimant's view reflected in their own can be specified in a recognized_by=* tag.
        2. disputes which have dispute=yes or disputed=yes, plus a list of disputant viewpoints in the disputed_by=* tag. when a viewpoint is listed in disputed_by then the boundary will have its kind:xx set to unrecognized_* (where XX is the viewpoint / country code and * is the kind of boundary it is).
    • earth: The former OpenStreetMapData.com source is now hosted by FOSSGIS at osmdata.openstreetmap.de and the source property has been updated. Issues (#1855) and (#1859)
    • landuse: Add kind_detail for aerodrome enhancement and backfill kind_detail on aerodromes with values, public, private, military_public, airfield, international, regional, gliding, and add optional aerodrome_passenger_count property indicating the number of passengers through the aerodrome per year sourced from Wikidata. (Issues #1277 and #1873)
    • places: Backfill country_capital and region_capital booleans from Natural Earth on high-zoom OSM features, including point-of-view. (Issue #1810)
    • places: Add point-of-view (POV) to capitals from Natural Earth data to all zooms. (Issue #1840)
      • country_capital:xx: when present, either true or false to override the country_capital value for XX's viewpoint. Note that the viewpoints are either lower-case ISO 3166-1 alpha-2 codes or the pseudo-code iso, same as for kind:xx on boundaries.
      • region_capital:xx: when present, either true or false to override the region_capital value for XX's viewpoint. Note that the viewpoints are either lower-case ISO 3166-1 alpha-2 codes or the pseudo-code iso, same as for kind:xx on boundaries.
    • places: Add wikidata_id Wikidata ID concordance to features. (Issue #858)
    • pois: Add optional Wikidata wikidata_id concordances. (Issue #858)
    • pois: Add kind_detail for aerodrome enhancement and backfill kind_detail on aerodromes with values, public, private, military_public, airfield, international, regional, gliding. (Issues #1277 and #1873)
    • pois: Distinguish military airfield from generic aerodrome. (Issue #1580)
    • roads: Ensure runways get kind_detail polish by intersecting them with landuse aerodrome polygons using new overlap function. (Issue #1852)
    • roads: Add missing railway types of disused, miniature, preserved. (Issue #955)
    • water: Add optional Wikidata wikidata_id concordances. (Issue #858)
    • water: The former OpenStreetMapData.com source is now hosted by FOSSGIS at osmdata.openstreetmap.de and the source property has been updated. Issues (#1855) and (#1859)

    BUG FIXES

    • boundaries: Rename unrecognized to unrecognized_country kind value to disambiguate POV on country, region, county, and other boundary types.
    • buildings: Check that building height is in a sensible range by limiting tallest structures to 1000 meters. (Issue #1850)
    • earth: Add variable min_zoom to low zoom features from Natural Earth. (Issue #1287)
    • places: Update Who's On First dump to reflect new and deprecated neigbourhoods. Issues (#1808) and (#1869)
    • pois: Prefer elevator over subway_entrance when both are true. (Issue #1876)
    • pois: Prefer memorial over plaque when both are true. (Issue #1872)
    • pois: Prefer bus_stop over generic transit platforms. (Issue #1874)

    • pois: Only set POI for harbour, port, port_terminal, ferry_terminal, container_terminal when they aren't also tagged as waterway, natural water, or landuse reservoir, basin features. (Issue #1590)
    • roads: Speed up road merging, for dense areas like Japan. (Issue #1847)
    • roads: Drop all name:* variants in addition to basic name to promote more feature merging. (Issue #1847)
    • roads: Remap Natural Earth's "trunk" roads to kind major_road instead of highway. (Issue #1280)
    • roads: Adjust min_zoom of OpenStreetMap highways and major roads to better match Natural Earth's min_zooms. (Issue #1279)
    • roads: min_zooms at zoom 5 are mix of 3, 4 and 5 instead of just 5.x. (Issue #1074)
    • roads: Add low-zoom toll property from Natural Earth to match earlier high-zoom data from OpenStreetMap. (Issue #1817)
    • roads: Add new road construction kind with kind_detail from the usual kind from zoom 12+. (Issue #394)
      • kind_detail: motorway, motorway_link, trunk, primary, secondary, tertiary, trunk_link, unclassified, residential, road, primary_link, secondary_link, living_street, service, pedestrian, track, cycleway, bridleway, tertiary_link, footway, steps, corridor
    • water: Reduce the marine water labels visible at zoom 8 by limiting number of bays in the tile to the largest 10. (Issue #1838)
      • The kinds bay, strait and fjord are ranked by size and given a kind_tile_rank property that starts from 1 and counts up as the feature gets smaller. Note that the ranking is done on a "metatile", which means that each tile (of size 256px, 512px or other) won't necessarily contain the full range from 1 to N of kind_tile_ranks.
    • water: Water boundary lines now indicate intermittent property (playas), matching their polygons. (Issue #1249)

  • Requires: tileserver v2.0.0 and tilequeue v1.7.0 and mapbox-vector-tile v1.2.0.

    ENHANCEMENTS

    • Show important cycling and walking routes at earlier zooms by adjusting the min_zoom of path, major_road, and minor_road cycling and walking related features in the roads layer. This means that min_zoom values are now variable for features of the same kind, depending on their importance in the bicycle and walking networks; in earlier releases they all shared the same min_zoom. See #1172.
    • Add shields for bicycle, walking, and bus networks with new bicycle_network, walking_network, bus_network, bicycle_shield_text, walking_shield_text, bus_shield_text, and all_* variants onto road layer features. See #775, #1175, and #1214.
    • Add bicycle property to non-path road layer features to more accurately reflect is_bicycle_related routes (eg for ways tagged bicycle=designated). See #1171.
    • Add surface property to roads layer features. See #1020.
    • Add ramp and ramp_bicycle property to roads layer features. See #1147.
    • Remove motor_vehicle, horse and some other properties at low- and mid-zooms in roads layer. See #1224 and #1214.

    • Fix test failures based on upstream OpenStreetMap data changes.
    • NOTE: while the v1.3.0 release was tagged correctly the VERSION file was stuck at v1.2.0 leading to the incorrectly report in Python installs as v1.2.0.

v1.2.0

  • Release date: 2017-03-23. Live on prod 2017-03-27.
  • Requires: tileserver v1.4.0 and tilequeue v1.6.0 and mapbox-vector-tile v1.2.0.

  • See detailed Breaking changes, New features, Bug fixes, and Internal Changes sections below.

  • Requires: tileserver v0.8.0-pre2 and tilequeue v0.11.0-pre2

    BREAKING CHANGES (v1.0.0-pre2)

  • all layers: Revert to 2 letter language codes to remove client 3-char to 2-char shim logic, with better fallbacks. (#972)

  • boundaries, places, and roads layers: Remove raw Natural Earth scalerank (see min_zoom instead) and labelrank properties. (#992)

  • buildings layer: remove label placements from low- and mid-zooms, keep at zoom 16+. (#679)

  • landuse layer: Low- and mid-zoom landuse polygons are now merged within the same kind values to significantly reduce file size. Some properties, like name, id, sport, religion, and surface are dropped, and the area is recalculated for new combo polygons. Planned work will add back some detail by adding scale_rank classes pre-merge (matching buildings layer behavior). (#583)

  • landuse layer: Remove label placements for cemetery, farm, forest, forest, golf_course, grave_yard, military, national_park, natural_forest, natural_wood, nature_reserve, park, pitch, plant, protected_area, quarry, recreation_ground, substation, village_green, wastewater_plant, water_works, winter_sports, wood, works features, moving them to pois layer. Remaining label placements are recommended for text only label treatment.(#742)

  • landuse layer: remove label placements from low- and mid-zooms, keep at zoom 15+. (#679)

  • places layer: Additional locality changes for places layer to normalize place layer kinds: capital changes to country_capital, state_capital changes to region_capital, scientific_station localities get their own kind_detail, and other bug fixes for (#840). (#931)

  • pois layer: Remove the cuisine property (see new kind_detail instead). (#719)

  • pois layer: Modify default min_zoom for gate features. Gates on major roads are now visible at zoom 14, gates on intermediate roads at zoom 15, gates on minor roads at zoom 16, and gates not on roads at zoom 17 (was all zoom 15). (#820)

  • roads layer: Remove aerialway, highway, piste_type, railway, in favor of coalescing their values into a new kind_detail property (and change incorrect subkind reference in documentation to kind_detail). (#970)

  • transit layer: rename root_relation_id property to root_id, matching new building layer configuration. (#969 and #653)

  • water layer: Remove duplicative and poor resolution sea polygons (but keep their label centroids) to save Venice and other cities from early global warming! This also addressed excessive sea labels in most Mapzen house styles. (#951)

    NEW FEATURES (v1.0.0-pre2)

  • tilejson: Major upgrade to reflect all layers and properties. (#938)

  • versioning: Add semantic versioning (semver) document detailing the promises Tilezen makes about major, minor, and patch versions and data model changes. (#948)

  • buildings layer: Building parts may receive a root_id corresponding to the building feature, if any, with which they intersect. (#653)

  • landuse layer: Add graveyard features. (#742)

  • landuse layer: Add camp_site features for camp grounds. (#875)

  • pois layer: Add cemetery, farm, forest, forest, golf_course, military, national_park, natural_forest, natural_wood, nature_reserve, park, pitch, plant, protected_area, quarry, recreation_ground, substation, village_green, wastewater_plant, water_works, winter_sports, wood, works features with adjusted zoom ranges over their previous availability in the landuse layer as label placements. All remaining label placements in the landuse layer are no longer recommended for icon label treatment. (#742)

  • pois layer: Add graveyard features. (#742)

  • pois layer: Add art gallery features. (#990)

  • pois layer: Add kind_detail property sourced from sport for pitch features and sourced from cuisine for biergarten, pub, bar, restaurant, fast_food, cafe kinds (removing the cuisine property). (#719)

  • roads layer: To support highway shields a new shield_text property has been added, network values have been normalized (and bicycle networks are now excluded). An example: for "US 101" we now store network of US:US and shield_text of 101. Multiple shields are supported via optional all_networks and all_shield_texts lists (which work in GeoJSON and TopoJSON but not MVT formats, follow mapbox-vector-tile/#64 for a fix). The ref property remains available but is less useful for shield construction. (#192 and #896)

    BUG FIXES (v1.0.0-pre2)

  • all layers: Support fractional zoom for POIs, places, and other featues which were only appearing at the next whole integer tile, and rounds min_zoom values to 2 decimal places. For example: a feature with min_zoom of 14.8 was only appearing in zoom 15 tiles when it should have appeared in the zoom 14 tile. (#976)

  • boundaries layer: Correct bug where sort_key mapping wasn't updated for new boundary kind values from v1.0.0-pre1. (#1012)

  • places layer: Adjust default zoom ranges for Natural Earth localities at the low-zooms and Natural Earth and OpenStreetMap localities at mid- and high-zooms. (#981 and #982)

  • places layer: Exclude region_capital=false properties. (#1003 and #931)

  • pois layer: Add OpenStreetMap source attribution per feature. (#922)

  • pois layer: Start querying for pois at z4, not z2 (matching the landuse layer). (#994)

  • pois layer: Show large camp_site features at earlier zooms. (#875)

  • pois layer: Removed transit halt, station, stop, and tram_stop features marked as historic. (#661)

  • pois and landuse layers: Normalize operator values for United States National Park Service, United States Forest Service, and National Parks & WildlWildlifeife Service NSW in the U.S.A. and Australia. (#927)

  • roads layer: Pedestrian paths and piers were missing bicycle: designated and related tags. Now that they are exported, they are correctly also decorated as is_bicycle_related: True. (#832)

  • roads layer: Add additional properties sidewalk_left and sidewalk_right to all road layer features. (#605 and #986)

  • roads layer: Remove crossing, sidewalk, sidewalk_left and sidewalk_right properties for road merge. (#993)

  • roads layer: Drop meaningless id property on merged features. (#952)

  • transit layer: Add OpenStreetMap source attribution per feature. (#935)

    DOCUMENTATION CHANGES (v1.0.0-pre2)

  • documentation: Update earth layer documentation to reflect additional line and point geometry types. (#808)

  • documentation: Update boundaries and landuse layer documentation to reflect barriers moving into the landuse layer. (#932)

  • documentation: Update buildings layer documentation to reflect new kind and kind_detail values and building_part changes. (#933) and related (#842)

  • documentation: Update roads layer documentation to reflect new kind and kind_detail values, and remove erroneous reference to exit. (#936)

  • contributing: Adding a step to create a test_config.yaml file. (#1001)

    INTERNAL CHANGES (v1.0.0-pre2)

  • performance: Move label centroid calculation to database to reduce network pressure on the database (post processing transform needed too much geometry) in landuse, water, earth, and buildings layers. (#965)

  • Requires: tileserver v0.8.0.dev0 and tilequeue v0.11.0.dev0

    BREAKING CHANGES (v1.0.0-pre1)

  • new url scheme: Mapzen now offers several different types of tiles in vector and raster formats and we combine data from multiple sources. The URL scheme has been updated to reflect this, and emphasize versions. The old URL will continue to work (~1 year), but updates will stop once v1.0.0 is released to production. (#652)

    • New dev URL: http://tile.dev.mapzen.com/vector/v1/all/{z}/{x}/{y}.topojson

  • buildings layer: Reduce building payloads by merging buildings of similar type at zooms 13, 14, and 15 by dropping some properties like name, addr_housenumber, and addr_street, and quantizing others like height to 10 meters (zoom 13), 5 meters (zoom 14), and nearest meter (zoom 15). Also added new scalerank property with large buildings at 1 and small buildings at 5 to improve client-side style filtering & draw performance. (#845)

  • Remove landuse-labels layer in favor of label placements in landuse layer and pois features. (#852)

  • Use boolean values instead of 'yes' for properties likeosm_relation and label_placement. (#778)

  • Remove neighbourhoods from OpenStreetMap.
  • Add kind_tile_rank to kind=station features to enable filtering out of less important transit stations at low zooms (to reduce crowding). Weights stations that are shown at lower zoom levels by lines going through them. Lower numbers = more important.
  • Stop duplicating building footprints into the landuse layer, and exclude building=no features. Include all building properties at all zooms (was limited to high zooms).
  • Use addr:housename as building name if feature is a POI
  • Add aerialway line features into the roads layer.
  • Add back missing roads on park and other landuse boundaries that went missing when landuse_kind intercut was added.
  • Add service levels to railroads features in roads layer to distinguish importance.
  • Updated High Road classifier (zoom range, sort order) for service roads, including pedestrian streets, paths, and forest tracks so they are visible earlier.
  • Add volume on building layer polygons to enable more sophisticated client-side filtering at mid zooms.
  • Add city_wall lines and barrier lines to boundaries layer.
  • Fix minor bug around missing water layer boundary lines.
  • Add area to water boundary lines (so filtering of boundary lines can match polygons).
  • Add townhall, laundry, dry_cleaner, and ferry_terminal to pois layer.

v0.4.1

v0.4.0

  • Release date: 2015-10-06. Live in prod: 2015-10-20.
  • Fix regression in v0.3.0 where zooms 0 to zoom 8 country and region (state, province) features from OpenStreetMap were dropped from tiles (rolling back a change in v0.2.0)
  • Greater diversity of label placements for POIs, landuse, and buildings result in more balanced selection of features visible at mid and high (neighborhood) zooms. The feature's minimum recommended visible zoom is now included as a property (eg: min_zoom=10.7763), useful for determining feature priority in client-side label collisions. Currently visibility should be calculated combined with area filters, we'll move that serverside in later releases.
  • Add label positions for water bodies to the water layer noted as label_position=yes.
  • Add label positions for buildings to the buildings layer noted as label_position=yes.
  • Landuse label positions are now additionally available in the landuse layer directly, noted with label_position=yes.
  • WARNING: The existing landuse-labels layer will be depreciated in a later release.
  • Add location and layer tags to buildings features in the buildings layer to determine if something is location=underground or layer=-1 (like BART stations in San Francisco).
  • Administrative boundary line improvements are back in the boundaries layer: now based on OSM relations, includes localized left- and right-names, and adds maritime_boundary=yes when the boundary is out in the deep sea. Note that this is slightly different than the maritime=yes tag that comes directly from OSM as we're calculating it using a custom spatial mask that will be improved over time.
  • Add ferry lines starting at zoom 8 to road layer.
  • Add airport runway lines starting at zoom 9 in the roads layer. Can be combined with landuse_kind attributes to throttle visibility.
  • Requires: tileserver v0.4.0 and tilequeue v0.4.0 and TileStache v0.4.0

v0.3.0

  • Release date: 2015-09-25
  • Source national_park, protected_area and other significant landuse boundaries from OpenStreetMap to generate AOI polygons and labels earlier starting at zoom 4 globally (was zoom 9). These features also gain protect_class and operator properties.
  • Add OSM roads and other features starting at zoom 8 (transition from Natural Earth data was zoom 9 in earlier releases). Natural Earth urban areas remain until zoom 9, though.
  • Add water boundaries for low zooms (from Natural Earth), to match earlier v0.2.0 work for OSM water boundaries at mid and high zooms.
  • Landuse AOI polygons now include a sort_key hint from the server for easier client side styling. The sort_key is used server side to make the landuse_kind predictable on roads.
  • Underground streams are now marked such with a additional is_tunnel property (zooms 11+)
  • Temporarily reverted changes to administrative boundary lines in v0.2.x that dropped some boundary lines and their kind attributes. They'll be back soon, better than ever.
  • Other minor bug fixes and optimizations.
  • Requires: tileserver v0.3.0 and tilequeue v0.3.0 and TileStache v0.3.0

v0.2.0

  • Release date: 2015-09-18
  • Add landuse_kind to features in roads and buildings layers based on the intersection with landuse layer features. TIP: custom style roads and buildings over parks and other area features to improves contrast.
  • Add calculated water boundary=yes line features to water layer to resolve funky "coastlines" crossing water polygons (where river and ocean polygons meet, and where adjacent river polygons meet). There are already stream lines in the water layer, but this might require an style update. TIP: In D3.js, set fill: none on linear features like streams and boundary=yes feeatures.
  • Added power station polygons to landuse layer with kind = plant, generator, or substation.
  • Add house addresses points to buildings layer with kind = address.
  • Resolve duplicate populated places from places layer. Natural Earth only used in low zooms, OSM only used in mid and high zooms.
  • Stop generating tiny invalid geoms that were making D3.js cry.
  • Requires: tileserver v0.2.0 and tilequeue v0.2.0 and TileStache v0.2.0

v0.2.0-prehistory
