CHANGELOG

v1.4.0

  • When checking to see if a tile has changed, compare ZIP file contents only. (See tilezen#152)
  • On WOF neighbourhood update, return a better error message for invalid dates. (See tilezen#154)
  • Remove "layers to format" functionality. (See tilezen#155)

v1.3.0

  • Roll back the use of psycopg2 connection pools. (See #149)

v1.2.1

  • Fix connection leak: Track connections before trying to use them. (See #150)
  • Fix issue processing WOF data with z coordinates: Ignore extra coordinates, e.g: z, in reprojection. (See #148)

v1.2.0

  • Improve performance of GeoJSON and TopoJSON format generation by using ujson (See #139)
  • Improve performance of MVT format generation by using builtin round function (See #144)
  • Reduce database pressure by use psycopg2 connection pools (See #141)
  • Reduce database requests by registering hstore/json (See #142)
  • Reduce memory usage during tile seeding (See #126)
  • Expose unique option for seeding tile generator (See #127)
  • Support long zooms (See #130)

v1.1.1

  • Use queue name from message to acknowledge message. See #134.

v1.1.0

  • Add command to dump the tiles of interest list to a text file
  • Add support for generating metatiles (see also: tapalcatl)
  • Add priority queues implementation
  • Increase topojson scale from 1024 -> 4096

v1.0.1

  • Add bbox filter to test for partial overlapping, rather than intersecting, the bbox.

v1.0.0

  • Update wof projection to 3857.
  • Update srid throughout from 900913 -> 3857.
  • Add basic size logging for the objects returned from queries.
  • Support multiple geometries in queries.
  • Add filter to intersect with padded bounds.
  • Conditionally store tile data. Print total storage counts for each tile.
  • Correct the buffered mvt format definition.
  • Convert wof min/max zooms to floats.
  • Update sample cfg to reflect latest choices.
  • Add pyclipper dependency to requirements.

v0.10.0

  • Improve json encoding
  • Add boroughs to wof processing
  • Add support for configurable area thresholds
  • Add l10n names to wof processing
  • Port used TileStache fork code to eliminate dependency
  • Add configurable bounds buffer support
  • Remove simplification, now a vector-datasource transform step
  • Ensure json properties are utf-8 encoded
  • Add support to generate s3 urls with no path
  • Handle empty strings when edtf parsing wof dates

v0.9.0

  • Delegate quantization to mapbox-vector-tile. See #82.
  • Expand mz_properties in features. See #81.
  • Exclude null values from yaml output. See #84.
  • Remove outdated tests exercising a transform that is no longer used. See 6de8f00.

v0.8.0

  • Use an empty list if the 'transforms' parameter is missing, rather than raise KeyError.
  • Metatile at z16
  • Support storing individual formatted layers
  • Pass context object to post-process functions.
  • Add resource abstraction to manage transforms with io requirements
  • Don't filter out small features at z16, which may be needed for subsequent zooms

v0.7.1

  • Eliminate extra slash in S3 filename. Issue.
  • Update make_queue signature to support sending items to the queue for rendering when a request for a tile which hasn't been rendered before is received. Issue as part of larger issue.

v0.7.0

  • WOF neighbourhoods with inception and cessation dates are now respected, with those features being hidden from tiles. Issue.
  • The WOF update process is now robust to intermittent HTTP errors. This could help if you've been experiencing occasional WOF update failures. Issue.

v0.6.1

  • Made the WOF processor robust to missing lbl:longitude and lbl:latitude properties by falling back to the geometry's position. This isn't as good as the label position, but better than erroring.

v0.6.0

  • Added a date prefix to be used to distinguish between different versions of the tiles in the store. This means it's not necessary to create a new bucket for each release.
  • Added a hash prefix for files stored in an S3 bucket. This is recommended practice for distributing load for a bucket across an S3 cluster.

v0.5.1

  • Move reproject_lnglat_to_mercator function for outside usage

v0.5.0

  • Configure better defaults in sample config
  • Add WOF neighbourhood processing
    • add command to load initial neighbourhoods to database
    • add command to track updates
  • Create abstraction to factor out threaded enqueueing

v0.4.1

  • Add bbox_intersection filter for Jinja, which allows clipping to the query bounding box.

v0.4.0

  • Convert post process config into a list, to support generating dynamic label_placements for more than one input layer.

v0.3.0

  • Add read_tile to store interface

0.2.0

  • Stable
