Hi,
I'm requesting help from good wills of the community to help us grow
our datasets of grids at
https://github.com/OSGeo/proj-datumgrid/
Below a few candidates I've identified, mentionned in EPSG and with a
number of them with
download links, but license clarification would be needed.
Community members from those countries are probably in a better
position than me to
connect with the relevant authority and see if they'd be willing to
adopt one of the licenses
mentionned at
https://github.com/OSGeo/proj-datumgrid#about-the-datum-grid-package
Spain
-----
* Peninsula and Baleares:
Anyone from the Spanish community to help clarifying license of
https://www.fomento.gob.es/recursos_mfom/gridshift1.zip (ED50 to ETRS89),
presumably whith IGN Spain
The download link is accessible from
https://www.fomento.gob.es/organos-colegiados/consejo-superior-geografico/csg/etrs89/etrs89-nuevo-sistema-de-referencia-geodesico-oficial-en-espana
This file has a sort of CC license
(https://gist.github.com/rouault/1ff4ad2d8053e068f9dbf451572692f4) but
with a
annoying non-modification clause that makes it incompatible with our
requirements
(we might want to transform it to another format like GeoTIFF),
and no version/link to the actual CC license.
* Catalonia:
Grid specific to Catalonia for ED50 to ETRS89 : 100800401.gsb
File found in
http://www.icgc.cat/content/download/48766/337962/version/1/file/Malla_NTv2_11_03.zip
but no explicit license mention.
https://www.icgc.cat/en/Web/Help/Legal-notice has a vague mention of
Creative Commons,
but no precise identification of which variant of it, and which version.
Austria
-------
The AT_GIS_GRID.gsb grid for MGI to ETRS89 is available at
http://www.bev.gv.at/portal/page?_pageid=713,2157075&_dad=portal&_schema=PORTAL
:
http://www.bev.gv.at/pls/portal/docs/PAGE/BEV_PORTAL_CONTENT_ALLGEMEIN/0200_PRODUKTE/UNENTGELTLICHE_PRODUKTE_DES_BEV/GIS-Grid.zip
Copyright info I could find is
"Hinsichtlich seiner Datenbanken verfügt das BEV über das ausschließliche
Werknutzungsrecht gemäß §§ 40f bis 40h UrhG und das sui generis-Recht
gemäß §§ 76c bis 76e UrhG."
which by itself is not super promising.
Slovakia
--------
https://www.geoportal.sk/en/geodeticke-zaklady/download/ offers for
download 3 grids
referenced by EPSG:
Slovakia_ETRS89h_to_Baltic1957.gtx
Slovakia_ETRS89h_to_EVRF2007.gtx
Slovakia_JTSK03_to_JTSK.LAS / .LOS
I've emailed the contact mentionned on the site to get info regarding
the license.
But wouldn't hurt to get feedback of knowledgeable people too.
Brazil
------
Looking for official download links & license for the following:
Corrego Alegre 1961 to SIRGAS 2000: CA61_003.gsb
Corrego Alegre 1970-72 to SIRGAS 2000: CA7072_003.gsb
SAD69 to SIRGAS 2000: SAD69_003.gsb
SAD69(96) to SIRGAS 2000: SAD96_003.gsb
https://www.killetsoft.de/p_gdln_e.htm has download links but official
ones from IBGE
would be preferable if possible.
Of course there are certainly gaps to fill for other countries I've
not mentionned...
Even
access to projection grids for Brasil. thanks. -jeff

In summary: once these Brasil grids are added to the PROJ library, then
they can be distributed in QGIS and therefore give accurate projection
readings for all QGIS users in Brasil :)
Please consider helping Even Rouault get access to those grids, so he
can add them into the PROJ library.
thanks,
-jeff

Hi Julio,
Thank you, great news!
I have filed an associated ticket in PROJ for these grids, it would be
great if you can also comment there:
https://github.com/OSGeo/proj-datumgrid/issues/101
Specifically, it would be great if you (or others) can clarify inside
that ticket what is the exact license of those grid files, provided by IBGE
Thank you again! :)
Wishing you a happy 2020.

Hi Jeff,
I wrote to IBGE agency again, asking about NTV2 grid data license and suggesting a PROJ4 compatible for the grid data, keeping Progrid.exe software license as is.
I think it is possible to use an open licence for data files.
cheers
