[PROJ] Motion: adopt RFC 5

[Kristian Evers]

Even,

That is awesome. What is the procedure from now with regards to
releasing PROJ-data packages? The RFC says that we will be producing
a proj-datumgrid-geotiff-1.0 package (I guess we will call that proj-data-1.0?)
but how is that archive produced? Similar to the old grid packages, e.g.

mkdir build
cd build
cmake ..
make dist

Would be nice to have a HOWTORELEASE file to capture this knowledge.

Does the release procedure also require as CDN sync or is that done when
new files are registered?

Hi,

RFC 5 implementation has now been merged into PROJ master, and in the 
https://github.com/OSGeo/PROJ-data repository (was known transiently as proj-
datumgrid-geotiff), which is now the new home for grids & similar datasets.

https://github.com/OSGeo/PROJ-data/tree/master/grid_tools contains the tools & 
documentation to create Geodetic TIFF grids (GTG)

And https://github.com/OSGeo/PROJ-data/blob/master/CONTRIBUTING.md contains 
the workflow to follow for adding new data.

For now, https://cdn.proj.org/ contains both the initial grid names (like 
egm96_15.tif), and the new ones following RFC 5 naming scheme 
(us_nga_egm96_15.tif)
I'll remove next week the old files, so for the initial adopters of RFC 4, 
please update to latest master now, so proj.db points to the new names.

Even
