9.2.0 Release Notes

Updates

• Database

  • EPSG updated to EPSG 10.082 (#3609)

  • ESRI objects updated to v3.1.0 (#3575)

  • Added Slovenian geoid model SLO-VRP2016/Koper (#3610)

• Projections

  • Added generic Space Oblique Mercator (#3338)

  • Inverse eck4: Add checks for projection domain (#3625)

• Transformations

  • Added support for NADCON5 grids and transformation method (#3510)

  • Added option ONLY_BEST=YES (#3535)

    When enabled only use the best possible transformation between two CRS's can be
    instantiated. If the best possible transfomations can't be instantiated it will
    fail instead of opting for the next best transformation.

    With ONLY_BEST=YES a transformation will fail if a needed grid is unavailable.

    The option can be toggled in proj.ini and with --only-best in cs2cs.

  • Implement 'Similarity transformation' (EPSG:9621) and import related
    tranformations from EPSG (#3578)

  • Optimise transformations between GDA94, GDA2020 and WGS84 (#3621)

• Performance improvements

  • Pass PJ_COORD by reference for fwd4d and inv4d callbacks (#3503)

  • Improved of inverse meridian length calculations (#3516)

  • Avoid very poor performance on a geographic CRS whose datum name is the alias of an official one (#3624)

• Well-Known Text improvements

  • Support WKT:2019 COORDINATEMETADATA[] construct (#2711)

  • implement alterCSLinearUnit for CompoundCRS (#3325)

  • Added PJ_TYPE_DERIVED_PROJECTED_CRS (#3488)

  • Added support for ISO19111 CoordinateMetadata class (#3562)

  • Update WKT import to support WKT2 corrigendum (#3573)

  • WKT import: Make axis direction and range meaning enumeration case
    insensitive as mandated by spec (#3577)

  • Implement AffineCS and handle it in WKT (#3579)

  DEPRECATIONS

  The following functions have been deprecated and will be removed in a future version.

  • C API function proj_rtodms. Use proj_rtodms2 instead (#3431)

  • C experimental API function proj_create_conversion_tunisia_mapping_grid().
    Use proj_create_conversion_tunisia_mining_grid() instead (#3559)

  • C++ API function createTunisiaMapingGrid(). Use createTunisiaMiningGrid() instead (#3559)

  • Added explicit NaN handling to proj_trans and gie (#3603)

• CMake

  • Added uninstall target (#3362)

  • Adopted use of TIFF:TIFF and CURL::libcurl targets (#3374)

• Implemented stricter matching by name to avoid false positives (#3487)

• Improved numerical accuracy of the meridian length calculations and its inverse (#3516)

• Added PROJ_IGNORE_CELESTIAL_BODY=YES environment variable that allows better matching of
  non-earth shaped ellipsoids to other celestial bodies (#3569)

Bug fixes

• rtodms(): fix potential buffer overflow not dealt with (#3441)
