Changelog

Unreleased

5.10.2 - 2024-10-06

Fixed

  • Fix off by 1 error when computing certain British/Irish grid references

5.10.1 - 2024-09-24

Fixed

  • Compatibility with opcache preloading

5.10.0 - 2024-08-23

Added

5.9.2 - 2024-08-18

Changed

  • Split declaration of the Projected::EPSG_* constants into multiple files internally to aid with static analysis in IDEs (there are so many, the file defining them was over the max file size analysis threshold for Intelephense)

5.9.1 - 2024-08-15

Changed

  • Updates to data for USA and WGS84
  • Support for Irish polynomial transformation in the ETRS89 to TM75 direction (TM75 to ETRS89 was already supported)

Fixed

  • British and Irish Grid references were rounding rather than truncating causing a sometimes off-by-1 error

5.9.0 - 2024-08-04

Changed

  • Updates to data for Czechia, Denmark, ETRS89, Germany, Martinique, Portugal, St Helena, UK and WGS84

  • The namespace of all *Point classes have been tidied up and changed to from PHPCoord to PHPCoord\Point e.g. PHPCoord\GeographicPoint is now PHPCoord\Point\GeographicPoint. An alias has been provided, all existing code referencing the old names will continue to work

5.4.0 - 2023-05-27

Added

  • Added getSupportedSRIDsWithHelp() as a version of getSupportedSRIDs() that returns at runtime the inline help available within the source code

  • Support for converting coordinates from a CompoundPoint where the horizontal component is Projected to a 3D CRS

Changed

  • Updates to data for ETRS89, Colombia, Slovenia, USA and UK

Fixed

5.0.1 - 2022-01-29

Fixed

  • Guard against divide by zero issues when calculating distance between two points

5.0.0 - 2021-11-12

Added

  • Support for IGN France geocentric translation by grid interpolation. This requires the Europe datapack
  • Support for vertical grid files. These require a relevant datapack

Changed

  • The signatures of all *Point::create*() methods have been changed to put the CRS first. Previously the distance/direction values came first. This is to ensure that all optional parameters are at the end of the signature, addressing a PHP8.1 deprecation.

    Example:

    // in v4
GeographicPoint::create(
    Angle $latitude,
    Angle $longitude,
    ?Length $height = null,
    Geographic $crs, // was after distance/direction
    ?DateTimeInterface $epoch = null
): GeographicPoint

// in v5
GeographicPoint::create(
    Geographic $crs, // now goes first
    Angle $latitude,
    Angle $longitude,
    ?Length $height = null,
    ?DateTimeInterface $epoch = null
): GeographicPoint

  • Updates to data for Canada, Norway, UK

  • Some internal simplifications and optimisations

  • Supported PHP versions changed to ^8.0

4.7.1 - 2024-01-26

The v4.x series is receiving basic maintenance only. All feature development takes place in v5.x. This is because one of PHP8.1's new deprecations required a significant non-backwards compatible change to address.

Fixed

  • Buffering of Irish extent

4.7.0 - 2022-06-26

Added

  • Support for defining 3D projected coordinates

Fixed

  • Improved handling of longitudes greater than 180 degrees

Added

  • Added UTMPoint as a better way of handling UTM zones than the EPSG model does it
  • Improved conversion chaining for CompoundPoints

Changed

Added

  • Support for accepting 2, 4, 8 and 10 figure Ordnance Survey references (6 figure was already supported)

Changed

  • fromSixFigureReference
  • All value objects are now immutable - calling a conversion function on them now returns a new object rather than modifying the existing one
  • Minimum PHP version is now 7.1

Removed

  • HHVM support now that project has a stated goal of no longer targeting PHP7 compatibility
  • OSRef::fromSixFigureReference() has been removed, use OSRef::fromGridReference() instead

Initial release of this fork (based off of v2.3 of original)

Fixed

  • When converting Latitude and Longitude between WGS84 and OSGB36 or vice-versa, a wrong constant for the y translation has been corrected (was off by 1 metre)

Changed

  • Eastings and northings are rounded to 1m, and lat/long to 5dp (approx 1m) to avoid any misconceptions that precision is the same thing as accuracy.
  • When calculating surface distances, a more accurate mean radius is now used rather than that derived from historical definitions of a nautical mile
