1.2.2

What's Changed

• Updated algorithm to split aoi when no linear features by @Sujanadh in #31
• Also only split by major highways, no minor roads.

Full Changelog: 1.2.1...1.2.2

v1.2.1

What's Changed

• Clip square grid with AOI by @Sujanadh in #27

Full Changelog: 1.2.0...1.2.1

v1.2.0

What's Changed

• Refactor out geopandas in favour of shapely by @spwoodcock in #25
• Better handling of FeatureCollection multiple geometry input (no convex_hull, instead splits per specific area, then merges the output together).

Full Changelog: 1.1.2...1.2.0

v1.1.2

Fixes related to data extract generation:

• Add missing railway and aeroway tag filtering.
• Add useStWithin=false to raw-data-api queries for polylines.
• Use YAML format config for query generation.

Data extract generation should now work as intended.

Full Changelog: 1.1.1...1.1.2

v1.1.1

• Improved parsing of AOI boundary strings.
• Option to not include data extract in split_by_sql:
  • The data extract is generated automatically by the osm-rawdata module.
  • If a data extract is passed, splitting is attempted using the custom extract.

v1.1.0

• Added support for parsing AOIs with multiple geometries.

v1.0.0

As v1.0.0rc0

Additions:

• Now accepts SQLAlchemy Session objects, in addition to psycopg2 connection or db connection string.

  # Previously
  sqlalchemy_session = SessionLocal()
  psycopg2_connection = sqlalchemy_session.connection()
  split_by_sql(psycopg2_connection, ...)
  
  # Now just pass the sqlalchemy session directly
  sqlalchemy_session = SessionLocal()
  split_by_sql(sqlalchemy_session, ...)

• Suppressed noisy geopandas warnings.

v1.0.0 Release Candidate 0

• Removed SQLAlchemy and GeoAlchemy dependencies.
• Usage of the splitBySQL method now requires either a connection string, or psycopg2 connection.
• SQLAlchemy Session objects are no longer accepted.

To get the psycopg2 driver connection from an SQLAlchemy Session, it's as simple as using:

psycopg2_connection = sqlalchemy_session.connection()
# Then pass psycopg2_connection as the db variable

Advantages

• The updated code uses a single database transaction instead of three.
• The tables will be dropped with the CASCADE option at the start of the script:
  • This prevents conflicts if osm_ways or osm_lines already exist in the db, likely from previous fmtm-splitter versions.
• Reduction in sub-dependencies required to install this module.

v0.2.6

• Minor fix to parse tags as JSON prior to insert into database (using geopandas.to_postgis).

v0.2.5

• Return descriptive error if data extract is empty or incorrectly parsed.
• Handle case where 'tags' key in data extract is a JSON string (i.e. with escape characters).
  • This would fail previously due to attempt to .get() a string.
  • The use case was for flatgeobuf --> geojson deserialisation. Sometimes nested props are generated as JSON string in the GeoJSON. This could be during flatgeobuf generation, or during the fgb --> geojson deserialisation.
  • The workaround parses the 'tags' key as a dict, else skips the tags for a feature (if parsing fails).
