In PROJ: Generic Coordinate System Transformations Using 'PROJ'

PROJ 0.6.0

• Fixed bashism for CRAN in configure, thank you.

PROJ 0.5.0

• proj_trans() is no longer supported with list input, and returns matrix output.

• PROJ >= 6 is now a hard dependency (#42)

• Deprecate ok_proj6() (#42)

• Add {wk} transformer api (#44, #46, #48, #50)

• Replace proj_trans() with S3 generic (#56)

PROJ 0.4.5

• New function proj_version().

• reinstated proj function!

• ok_proj6() is now meaningful again.

• Deprecated old proj_trans_generic().

PROJ 0.3.1

• New function 'proj_crs_text()' to convert from one CRS text format to another.

• No set up on load now, all handled by libproj. Package should always function, always with version 7 or above.

• FIXME: (should deprecate) Removed ok_proj6()

• Now importing libproj, to provide cross platform access to PROJ version 7 and above and for configuration of metadata files.

• Incorporated fixes and improvements from Dewey Dunnington.

PROJ 0.2.0

• Now using Github Actions to test linux, windows, macos. Many thanks to James Balamuta for guidance on how to do this.

• The internal C functionality calling the PROJ library now uses .Call rather than .C. The .C function PROJ_proj_trans_generic() is now not used and will be removed.

• On load behaviour has changed, on Windows and MacOS a check is made for a local copy of the proj/ PROJ data directory with metadata files. If this is present, the path to that folder is set using the underlying PROJ library function proj_context_set_search_paths().

This is only relevant to Windows and MacOS static builds, these are self-contained, the R package contains the PROJ library and everything it needs. Generally in other installations (brew on MacOS, apt install, or from source builds on Linux) the PROJ library self-configures and knows where to find this directory.

This is automatic for source builds on Windows which download pre-built binaries and data from https://github.com/rwinlib, and so will be using a given PROJ version.

On MacOS, this only occurs if configure options --with-data-copy=yes and --with-proj-data=DIR are used. This is done manually on CRAN by admins. The current version used can be found at https://mac.r-project.org/libs-4/.

• Need proj version 6.1.0 or above, and a configuration fix on MacOS for libsqlite thanks to Brian Ripley, and CRAN.

• Fixed bug not returning transformed z or t.

• Windows: update to proj 6.3.1

PROJ 0.1.6

• We now use the PROJ::proj_trans internally, and just loop over vectors. (so proj_trans_generic is a misnomer, technically).

• Prevent error on out of bounds values from proj_trans_generic(). We get Inf.

PROJ 0.1.5

• Attempt to fix errors on CRAN, add missing test for functionality with required lib-proj version and use more generic initialization string.

• New function [proj_create()] to generate CRS formats from various input types.

PROJ 0.1.0

• Removed CPP variable from configure thanks to CRAN.

• Sorted out .C registration.

• Now set data directory for installed share files, thanks to Jeroen Ooms for the nudge in the right direction with the R API.

• Cleaned up CI testing, so we get tested on versions 5, 6, and 7 of PROJ on travis.

• Removed proj_trans(), only function is proj_trans_generic() more closely aligned to the API of PROJ itself (=> 6).

• Included PROJ library tooling for Windows, thanks to Jeroen Ooms.

PROJ 0.0.1.9001

• Remove Rcpp.

PROJ 0.0.1

• R function proj_trans() gains a quiet argument to control output of warnings about missing values.

• New C functions R_proj_trans_FWD() and R_proj_trans_INV() using the base R API. Interface is matrix in, matrix out always with three columns out as per reproj.

• First working code with Rcpp function proj_trans_cpp().
