proj4 1.0-14 (2024-01-14)

• minor change to error messages

proj4 1.0-13 (2023-08-17)

• update Rtools43 flags (Windows only)

proj4 1.0-12 (2022-11-30)

• switch UCRT Windows flags to use PROJ6 API

proj4 1.0-11 (2022-01-31)

• improve detection of correct flags using pkg-config where available including static versions. Unless --enable-proj6 is used it will use proj4 API if avaiable.
• add support for UCRT Windows builds

proj4 1.0-10.1 (2021-01-26)

• force C++ in configure tests

proj4 1.0-10 (2020-03-02)

• remove dead links from the documentation

proj4 1.0-9

• update proj4 to support PROJ5 and PROJ6. Given all the issues with the new PROJ6 API we try to use PROJ4 API wherever possible. It is, however, possible to force the use of PROJ6 API even if PROJ4 is available by specifying --enable-proj6 configure flag. This should be only used with caution as it may have adverse effects on the projection results. When PROJ6 API is used, we are applying a heuristic in ptransform() to try to detect whether degrees are expected by PROJ6 instead of radians previously and will convert coordinates automatically to preserve the PROJ4 behavior.
• use NAMESPACE C symbol registration
• 2x2 input in project() was ambiguous, it is now defined that columns are taken as x and y. Note that previously rows were taken which is unintuitive and could lead to bugs that are hard to detect.

proj4 1.0-8 (2012-08-05)

• remove Windows binaries from the source package, respect LOCAL_SOFT environment variable to use local copy, otherwise fetch Windows binaries from RForge.net

proj4 1.0-7 (2011-12-11)

• use R's CPPFLAGS and LDFLAGS for testing in configure, addressing issues on systems with non-default proj4 location which is known by R.

proj4 1.0-6 (2011-02-01)

• Update bundled PROJ.4 library for Windows to 4.7.0 and include both 32-bit and 64-bit binaries (there is no change to the package itself)

proj4 1.0-5 (2011-01-17)

• fixed a minor typo in the docs
• changed license specification from verbatim form to a form that R likes better

proj4 1.0-4 (2007-06-10)

• add ellps.default to project() (PROJ4.5.0 always requires an ellipsoid or datum)
• fix examples to work with PROJ4.5.0

proj4 1.0-3 (2007-06-07)

• add Windows support

proj4 1.0-2

• update documentation
• add support for datum transformation via ptransform()

proj4 1.0-1

• add a namespace
• allow projection parameters to be specified in a more flexible way including a named vector c(proj='utm',zone=15), a list list(proj='utm',zone=15) and an unnamed arguments vector c('+proj=utm','+zone=15').

proj4 1.0-0

• initial version (an intereface to pj_fwd and pj_inv) Note for Windows: This package contains a static proj4.7.0 binary for Windows. The NAD files are expected to be installed in c:\proj
