felt/geo_postgis

This system is an Elixir library that integrates the Geo and PostGIS ecosystems with Ecto, enabling robust spatial data handling within database schemas. It provides macros for PostGIS geometry operations and distance calculations, while supporting binary WKB encoding and multi-dimensional coordinate variants (Z/M). The library manages the casting and persistence of various geometry types, ensuring compatibility with modern Elixir and database driver versions.

This update adds several new PostGIS functions to the Ecto query interface, including \st\_distance\_in\_meters\ for accurate metric distance calculations, \st\_dwithin\ and \st\_dwithin\_in\_meters\ for proximity checks with optional spheroid support, and geometry manipulation macros like \st\_geometric\_median\, \st\_expand\, \st\_concave\_hull\, and \st\_collect\. It also corrects a typo in the \st\_crosses\ fragment (fixing 'ST\_Crosess' to 'ST\_Crosses') and updates the module documentation links.

The application configuration has been migrated from the deprecated \Mix.Config\ module to the modern \import Config\ syntax, requiring a minimum Elixir version of 1.11. In the test environment, the repository configuration has been updated to use \Geo.PostGIS.Test.Repo\ instead of \Geo.Ecto.Test.Repo\, and the logger level has been adjusted from \:warn\ to \:warning\ to align with current Elixir standards.

config · high confidence

The Postgrex extension for PostGIS has been updated to use the binary format (WKB) instead of text (WKT) for encoding and decoding geometry data, which changes the underlying storage and transmission method. This update also adds support for geometry types with Z (elevation) and M (measure) coordinates, including PointZ, PointM, PointZM, LineStringZ, LineStringM, LineStringZM, MultiLineStringZ, MultiLineStringM, MultiLineStringZM, and PolygonZ. Additionally, the extension now defaults to copying binary data during decoding rather than referencing it, and includes a new configuration module to allow users to specify a custom JSON library for GeoJSON casting.

This release adds support for the newly released \geo\ v4.0.0 while maintaining compatibility with v3.6.x and v3.7.x. It also introduces a \.formatter.exs\ file to standardize code formatting via \mix format\, updates the CI configuration to use GitHub Actions (replacing Travis CI) with Elixir 1.11+ and OTP 22.3, and refreshes the README to reflect current installation and usage patterns.

(repo-wide) · high confidence

Added comprehensive tests for the \Geo.PostGIS.Geometry\ cast function, verifying support for both string-keyed and atom-keyed maps for Points and GeometryCollections. The Ecto integration tests were updated to use the unified \Geo.PostGIS.Geometry\ type across all schema fields (replacing specific types like \Geo.MultiPolygon\ or \Geo.Point\) and now include explicit PostGIS extension setup. New tests were added to verify round-trip insertion and retrieval for 3D and 4D geometry types, including \PointZ\, \LineStringZ\, and \LineStringZM\, alongside existing 2D geometries.

This release upgrades core dependencies to their latest major versions, including Ecto 3.13, Postgrex 0.21, Geo 4.1, and Jason 1.4, while also updating documentation tooling to ex\_doc 0.40. To support these changes, the minimum required Elixir version has been raised from 1.4 to 1.11. Users should ensure their environment meets this requirement before upgrading.
