Attention

WARNING: From 9am on 19th August until 5pm on 2nd September there will be no access to the Stanage HPC cluster.

We will send an email to notify you when Stanage is back online and available for job submission.

Attention

The ShARC HPC cluster was decommissioned on the 30th of November 2023 at 17:00. It is no longer possible for users to access that cluster.

PROJ.7

PROJ consists of programs and a library for managing cartographic projections.

Usage

By running

$ module load libs/proj/4.9.3/gcc-4.9.4
or,
$ module load libs/proj/7.1.0/gcc-8.2.0

you

  • add several PROJ programs to your PATH environment variable

  • allow other programs to make use of (dynamically link against) the PROJ library

  • activate version 4.9.4 of the GCC compiler (as its C++ standard library is required when using PROJ.4)

  • activate version 8.2.0 of the GCC compiler (as its C++ standard library is required when using PROJ.7)

You can run proj to test that you are running the required version

$ proj
Rel. 4.9.3, 15 August 2016
usage: proj [ -bCeEfiIlormsStTvVwW [args] ] [ +opts[=arg] ] [ files ]

Documentation

Standard man pages are available for the provided commands/functions cs2cs, geod, proj, geodesic and pj_init.

These can be viewed using e.g.
