In+ersec+ion for Spatial People

The OSGeo announced the release of PROJ 4.8.0. PROJ is, like GDAL/OGR, an open source component at the core of many geospatial software. The last major release was in September 2009.

The major items according to the announcement:

• 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.

Here's the full changelog.
