PROJ 4.8.0 Released

The PROJ.4 project is pleased to announce the release of PROJ 4.8.0. This is a major new feature release and collects all the work done since the PROJ 4.7.0 release in September 2009. The NEWS file includes these major items:

  • Added the Natural Earth projection.
  • Added HEALPIX, rHEALPIX and Icosahedral Snyder Equal Area projections.
  • nad2bin now produces “CTable2” format grid shift files by default which are platform independent.
  • nad2nad removed, use cs2cs for datum shift operations.
  • projects.h no longer installed as a public include file. Please try to only use proj_api.h.
  • Add pj_get_spheroid_defn() accessor.
  • Added an alternate version of pj_init() that takes a projCtx (execution context) structure to address multithreading issues with error management and to provide a support for application hookable error reporting and logging.
  • Upgrade to EPSG 7.9. Some changes in ideal datum selection.
  • JNI bindings reworked, org.proj4.Projections deprecated in favor of org.proj4.PJ.
  • Added preliminary vertical datum support.
  • Fix various multithreading issues, particular in datum grid handling code.
  • Added support for the +axis= option for alternate axis orientations as part of a coordinate system (used for TM South Orientated support).
  • +proj=omerc implementatioin replaced with code from libproj4. +rot_conv flag no longer works, and some coordinate systems (ie. Malaysian) will need to use +gamma instead. “epsg” init file updated accordingly.
