OpenMapTiles 3.15.0 SNAPSHOT (3) (#160)

* clean-up: mvn spotless:apply * Long ferries (as per OMT PR 1486) * regenerate-openmaptiles.sh b3d67ed5b327c9059aeea0b3304772c6b4c8c7e9 (to match content of OMT PR 1489) * Add aboriginal lands (as per OMT PR 1489) * handle duplicate route relations (to match OMT PR 1501) * regenerate-openmaptiles.sh master, to match several OMT PRs which adjusted only YML * URLs in comments adjusted to match OMT PR 1560 * Convert separated addresses to dashed addresses * add brunnel (and layer) attributes only for certain zoomlevels, depending on feature size (matching OMT PR 1579) * unit test testInterstateMotorway(): brunnel tag for test line no longer available at Z8 * unit test testInterstateMotorway() clean-up: Z13 was tested twice * minor clean-up: fixed unit test naming * partial fix for differences in transportation_name layer The difference is between OpenMapTiles/master (OMT) and planetiler-openmaptiles/omt_3_15_0 (PT-OMT) (e.g. development versions). The point is, that while PT-OMT was using limit of "8km" for Z9-Z11, OMT is using limit "ST_Length(geometry) > 8000 / POWER(2, zoom_level - 9) AND zoom_level BETWEEN 9 AND 11". Some further differences still visible, hence further commits expected. * further adjustments to better match what is done with ferries in OMT ... (as per OMT PR 1486) But FERRY_MIN_PIXEL_SIZE is "too much" in the contexct of Planetiler, since it is applied within tiles, hence causes gaps in lines if a line "strikes a little" certain tile. Hence we will need to divert a little. * ferry minLength tweak + clean-up * mvn spotless:apply * fixed minor typo * minor reformatting * ferry line length filter replaced with min. zoom calculation hence the results are much closer to what OMT is doing for Z4-Z9 * testFerry() adjusted to match previous commit ferry test polygon with area 1 now qualifies for min. zoom 5 * clea-up of unused stuff + mvn spotless:apply * mvn spotless:apply * added TODO node for follow-up pull-request/simplification * clean-up: common getMinZoom() code moved to Utils * minzoom clipping for brunnel was adjusted do Z9-Z12 -> test adjusted too * clean-up * use same tolerance for all transportation items, like OSM does * clean-up, since ferry and non-ferry procesing is now same * we need regenerate to work with master branch for now * first sub-class search for agg_stop simplified a little * contains() used instead of indexOf() for better readability * numbers as list, not array, so that getFirst() and getLast() can be used * better trimming and filtring of housenumbers * adjusted handling of large house numbers * several unit tests collapsed to one with @ParameterizedTest + @CsvSource * AGG_STOP_SUBCLASS_ORDER simplified from Map to List * fixed major omission from previous commit * clamp() used to replace min()&max() combo * agg_stop now implemented * fixed typo in the error message * prepare IE and GB boundary geometry outside of synchronized{} * fixed typo in the error message * mvn spotless:apply * switch statements for IE and GB route networks simplified * avoid RouteNetwork->String mapping, not needed for anyMatch() * fix: attr. brunnel optional based on size on Z4-Z11, attr. layer optional between Z9-Z11 * tolerance change in transportation reverted, added note to README as per why * fix: monzoom for sea&co. is Z0-Z14 based on area, for the rest it is Z3-Z14 again based on area * clean-up: avoid doing area->side->area, do just area * regenerate-openmaptiles.sh 6c31841f4674f15e15afde346a060cf7c22e6cdd (to match content of OMT PR 1591) * relevant process() functions adjusted to match changes in transportation/mapping.yaml * regenerate-openmaptiles.sh master, instead of 6c31841f4674f15e15afde346a060cf7c22e6cdd (to match content of OMT PR 1591, in a cleaner way) * introduce duplicate housenumber filtering (matching OMT PR 1391) * (less related) clean-up: use isEmpty() instead if size check * testContainsHousenumber UT adjusted, since duplicate housenumber filtering is reducing amount of house numbers * use combination of uic_ref, name, network and operator as key for agg_stop sets If we rely on only on `uic_ref` we group together also stations which are too far apart (even different cities). With this combo results seem OK, e.g. all grouped stations are within around 950m (1000 pixels at Z14) of each other (1000 being used in `PARTITION BY LabelGrid(...` in `layers/poi/poi.sql` in OpenMapTiles). * agg_stop comparison made more explicit, since we want to match same exact one * mvn spotless:apply * name now important for agg_stop processing, hence name:es (ab)used for unit tests * agg_stop: simplified processing of nearest station Results still same, only ordering is different: - previously: agg_stop=1 first - now: FIFO * agg_stop: forther code simplification * fixed major typo introduced in previous merge * setMinPixelSize() + setMinZoom() used instead of areaToMinZoom() * clean-up: unused stuff removed * mvn spotless:apply * setAttrWithMinSize() used instead of getBrunnelMinzoom() getFerryMinzoom() kept since we'd like to replicate `sql_filter: ST_Length(...` from OMT * getMinZoomForLength() no longer used, hence removed * MIN_LENGTH value halved, to partially counter the effect of Planetiler applying the limit before merging * clean-up: LOG2 not used, hence removed * Revert "MIN_LENGTH value halved, to partially counter the effect of Planetiler applying the limit before merging" This reverts commit 8fb67075289f3028d31761dcc9564fc597adab36. * use 256px as buffer pixel override instead of MIN_LENGTH Make sure we have enough room (=whole next tile) when checking MIN_LENGTH, to avoid pieces of otherwise "long enough" lines to be excluded (thus creating "holes" or missing ends) in some tiles just because length in that particular tile is bellow limit. Given that MIN_LENGTH values translated to pixels are quite big (compared to {@code BUFFER_SIZE}), such missing pieces would be quite noticeable. This improves items mainly in Z12-Z13. * added BY_TEMP_HAS_NAME comparator to avoid its repeated construction during run-time * duplicate houcenumber processing simplified further * clean-up: get(0) replaced with getFirst() * clean-up: CPU-intensive prepare() moved out of synchronized block * regenerate-openmaptiles.sh 3cf77e2a542d8a369bb08bf2538cdde0b3effb2b (to match content of OMT PR 1423) * unit test adjusted for POI office class changes * regenerate-openmaptiles.sh master (to match content of OMT PR 1544) * added charging_station implementation matching OMT PR 1544 * use setMinPixelSizeBelowZoom() instead of uniAreaToMinZoom() * use setMinPixelSizeBelowZoom() instead of getFerryMinzoom() * fixed unit test, to match recent tweaks * regenerate-openmaptiles.sh master (to match content of OMT PR 1605) * Fix university office/amenity collision (to match OSM PR 1607) * Remove expressway from ramps * OsmMarinePoint+ne_10m_geography_marine_polys join via name limited to 50km distance * regenerate-openmaptiles.sh master (to match content of OMT PR 1604) * Revert "Add aboriginal lands (as per OMT PR 1489)" This reverts commit 899a0c5718734d5a746cdd84df2e1308614954c0. * added handling of aboriginal_lands/OsmBoundaryPolygon into Boundary and Place layers * big islands can now get rank lower than 3 * Add e-road and a-road for transportation z4 * testPolishHighwayIssue165() adjusted: e-road now takes precendence * regenerate-openmaptiles.sh master (to match content of OMT PR 1627) * regenerate-openmaptiles.sh fff7110aeb61882abfafe22d1618fbe6181d96cb (to match content of OMT PR 1620) * Expanded road route attributes (to match OMT PR 1620) * unrelated clean-up: use getFirst() * adjusted handling or null and empty ref * regenerate-openmaptiles.sh master (to match content of OMT PR 1620) * pointOnSurface() used instead of centroid() to make sure the point is within the boundary * adjusted deduplication of route_<n>_<something> attributes * clean-up of some previous adjustments of importantMarinePoints * clean-up: removed unused imports * mvn spotless:apply * OsmWaterPolygon minzoom calculation reverted to v3.14 and then adjusted for new 1/4 threshold * part of process(Tables.OsmWaterPolygon, ...) moved to setupOsmWaterPolygonFeature() * if feature with centerline has minzoom bellow Z9, use also a label point between minzoom and Z8 * bay point vs. centerline difference mentioned in the README * testWaterNameBay for small bay adjusted, testWaterNameBay for big bay added * testWaterNameLakeline and testWaterNameMultipleLakelines tweaked to use smaller test areas * mvn spotless:apply * added unit test which checks minzoom for admin_level=2 disputed border (derived from way) * fixed missing admin_level=2 disputed borders at Z3 * landuse fix for Z5: include all features from ne_50m_urban_areas * minDist and buffer tweaked for residential areas for Z6-Z8 to better match OpenMapTiles * landuse fix for Z5: unit test updated * bumped copyright statements * added/adjusted acknowledgments * fixed handling of Baikonur border in Kazachstan * fixed handling of Baikonur border in Kazachstan (2) * OSM boundaries only for Z5+, non-disputed for Z4+ * OSM boundaries only for Z5+, non-disputed for Z4+ - unit test adjusted * OSM Lake IDs at low zooms * testLakeZoomLevels(): NE lakes removed, checked now in testLakeNaturalEarth*() * Use ne_10m_admin_0_boundary_lines_land_disputed to fix missing South Sudan boundary * testNaturalEarthCountryBoundaries() extended to cover adjusted handling of ne_10m_admin_0_boundary_lines_land * OSM lake area limit increased 2x to match smallest NE lake * OSM lake area limit increased 2x even further to match smallest observed during Planet processing * clean-up: SMALLEST_OSM_LAKE_AREA renamed to OSM_ID_MATCH_AREA_LIMIT to better match what it is * mvn spotless:apply * properly handle center line vs. point also for lakes * clean-up: min() dropped since nothing sets minzoomCL to value higher than MINZOOM_BAY * Revert e-road and a-road. * Revert e-road and a-road. (follow-up) * added unit test to cover: More roads for z4. * improved handling of disputed KE:SS border: will work even if left/right reversed * new PolygonIndex.getIntersecting() used for OSM lake ID matching + increased unit test coverage * neLakeIndexes simplified into neLakeIndex * test several NE lakes also in testLakeNaturalEarthByName() * clean-up: synchronized NOT needed for PolygonIndex.put() * neLakeNameMaps will stay as is, otherwise same names from several NE tables will clash * neAllLakeInfos stays, since neLakeNameMaps contains only some and hard(er) to get all from neLakeIndex * added test for NE lake ame collision: bigger one gets to be matched * simplified NE->OSM lake matching: ignore small OSM lakes right away * minor speed-up: compare intersection area instead of intersction area ratio * fixed minor typo * minor clean-up * minor clean-up after previous changes * adjusted handling of TopologyException to match previous tweaks * mvn spotless:apply * tweaked error message, to better mach cases when TopologyException occurs * adjusted trunks: Z6+ by default, some from Z5, some even from Z4 * adjusted motorways: only some at Z4 * adjusted transportation: clip also construction links to Z9+ * unit tests adjusted to the recent changes * use merge() to avoid problems with concurrent updates * synchronized mergeId() added to avoid problems with concurrent updates * clean-up after cc797f9a * mvn spotless:apply * label point in water_name refactored using setMinPixelSizeBelowZoom() * clean-up: LOG2 removed since no longer used * refactored handling of TopologyException for easier troubleshooting of problematic polygons * fix invalid NE lake geometries + further TopologyException handling tweaks * TopologyException handling removed, since no longer needed after adding NE geometry fixing * clean-up after previous changes * OpenMapTiles 3.15 was released so we can use proper tag now * regenerate-openmaptiles.sh v3.15 to match official OpenMapTiles release * Revert "clean-up after previous changes" This reverts commit ee70382150a18acd738c6495da533240d2b18b3a. * Revert "TopologyException handling removed, since no longer needed after adding NE geometry fixing" This reverts commit d4fe59c0e5311e5475a057b9feb7c322bff56027. * minor clean-up * handle TopologyException also from intersects() * further tweaks for TopologyException handling * warnings demoted to debugs since we're going to re-try * bumped copyright statements * bumped copyright statements * print errors+stack-traces only after retries with fixed polygons since we are not able to raise issues with JTS if we do stuff with invalid/unfixed polygons * message about fixing NE lake geometry demoted: warn -> debug * omt_water message adjusted to make it more clear what it relates to * do NOT store fixed geom in separate variable to avoid 2nd fixing in fillOsmIdIntoNeLake() * one more error message rephrased for clearer context * Revert "print errors+stack-traces only after retries with fixed polygons" This reverts commit 7440973169a6bb87f276bdf415edcdb0a3922c3c. * strip stack-trace from TopologyException debug messages * fix OSM element geometry if not valid before trying to match NE lake This is same trick as done for NE lakes before. Thanks to that we then do not need to handle TopologyExceptions and do retries. * clean-up * clean-up: mvn spotless:apply
