  • 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: Always validate OpenStreetMap-sourced country, dependency and disputed labels against Natural Earth and new ISO and TLC point-of-views. (Issue #2075, #2076, and #2077 and pull request #2069)
    • 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)
    • pois: Add optional direction property, an integer indicating degrees from 0-359, for viewpoint kind features. Thanks @rwrx. (Issue #598 and pull request #1916)
    • 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: Upgrade to Natural Earth to v5.1.2, circa May 2022 (Issue #2074)
    • earth: Upgrade to osmdata.openstreetmap.de circa October 2021.
    • places: Upgrade to Who's On First neighbourhood features, circa October 2021.
    • 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: French region lines show too early, switch all from funky scale_rank mapping to Natural Earth's min_zoom property. (Issue #2062)
    • 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)
    • buildings: Remove small buildings, reduce building geometry details, and remove some properties at mid- and high-zooms. (Pull request #2052)
    • buildings: Ensure address points always have a min_zoom property (eg of 17 for generated address points). This is paired with a Tilequeue change to drop zoom 17 features from 512-px tile sized zoom 15 tiles to reduce tile size. (Issue #2023) and (issue #2032)
    • landuse: Drop properties at low- and mid-zooms to encourage more feature merging. (Issue #2009)
    • landuse: Show more medium-sized park polygons in cities at mid-zooms. (Issue #1995)
    • landuse: Tunnels for canal should draw under pedestrian plaza so adjust sort_rank for these and some other kinds. (Issue #1910)
    • landuse: Switch sourcing of resort upstream in OpenStreetMap to leisure from tourism.
    • roads: Remove name properties from short road segments where they don't have enough room to label. (Issue #2019)
    • roads: Adjust zooms for regional and local cycle network influenced features one zoom later. Drop more all_networks and all_shield_texts for more zooms. 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)
    • roads: Fix wrong encoding for CA:PE road network in Prince Edward Island, thanks @musculman. (Pull request #1958)
    • places: Adjust min and max zoom of several country labels, including France and Norway to improve visual hierarchy and reduce tile size.
    • places: Ensure Taiwan's country name is generic (and not objectionable to some).
    • pois: Add sanity checks to tz_estimate_parking_capacity to guard against bad data entry for some large parking lots.
    • pois: Switch sourcing of resort upstream in OpenStreetMap to leisure from tourism.
    • transit: Simplify geometries at low- and mid-zooms. (Issue #1980)
    • water: Remove name and other properties from low- and mid-zooms by kind to encourage more feature merging. (Issue #2010 and pull request #2047)
    • water: Delay showing mid-zoom canal features when they don't support boats (and indicate if true with new boat property), instead show them starting at zoom 11. (Pull request #2098)
    • water: Mark intermittent polygons when basin is of type infiltration or detention as OpenStreetMap often skips tagging those intermittent=yes explicitly. (Pull request #2096)
    • water: Mark "reservoir" water polygon feature with a reservoir boolean. (Pull request #2047)
    • water: Mark water polygon feature with a alkaline boolean when upstream OpenStreetMap value is lagoon, salt, or salt_pool. (Pull request #2047)
    • water: Tunnels for canal should draw under pedestrian plaza so adjust sort_rank. (Issue #1910)
    • water: Remove reservoir features that are covered with a "roof". (Issue #1982)
    • water: Remove low- and mid-zoom water labels from small polygons. (Issue #2003)
    • water: Ensure sea labels are visible at mid- and high-zooms, not just the max zoom. (Pull request#2103)
