This is the first release in the new PROJ-data series of PROJ resource file packages. The PROJ-data package includes all grids and other resources previously tracked by the proj-datumgrid series of packages as well as some new grids. All grids in the PROJ-data package have been converted to the new Geodetic Tiff Grid (GTG) format introduced in PROJ with RFC4. The advantages of the GTG format are

  • Grids can contain more metadata than previous formats used by PROJ
  • Grids are compressed, taking up significantly less space
  • Cloud optimized, for easy on-the-fly access to grids online via https://cdn.proj.org/
  • Advanced gridded models previously consisting of several files can now be contained in one file

The data in the PROJ-data package is mirrored on https://cdn.proj.org/. A network-enabled PROJ build can leverage the CDN and retrieve (parts of) grids as specific transformations need them.

PROJ-data can be used with PROJ 7.0.0 and newer.
