Changelog

v1.2.1

• ToPoint function uses ST_Centroid for polygons with less than 5 nodes.
• Package is now published to @mapbox/postgis-vt-util

v1.1.0

• New function Sieve which filters inner and outer rings from a multipolygon based on a minimum area threshold.
• Z function converted to SQL from PL/PGSQL.
• ZRes function converted to SQL from PL/PGSQL and overloaded to accept both floats and integers.

v1.0.0

This version brings lots of code cleanup and reorganization, with many backwards-incompatible changes.

• lib.sql has been renamed to the more specific postgis-vt-util.sql
• Underscores have been removed from function names, following PostGIS' convention
  • clean_int -> CleanInt
  • clean_numeric -> CleanNumeric
  • tile_bbox -> TileBBox
  • merc_buffer -> MercBuffer
  • merc_dwithin -> MercDWithin
  • merc_length -> MercLength
  • We've also moved to CamelCase for all other functions, but PostgreSQL is not case-sensitive in this regard so it's purely stylistic.
• LabelGrid no longer takes a pixel size parameter. You should now pre- multiply this into the grid size before calling the function.
• TileBBox now takes an optional SRID parameter to reproject the output.
• Several new functions have been added. See the README for descriptions.
  • Bounds
  • LargestPart
  • MakeArc
  • OrientedEnvelope
  • SmartShrink
