Official transformation of Hessen for the land survey register (ALKIS). #98

Closed ChristianMaierHVBG closed 1 year ago

ChristianMaierHVBG commented 1 year ago

This is the official transformation of Hessen for the land survey register (ALKIS).

I followed all the steps of contributing to PROJ-data. Hopefully everything works out.

I also registered the transformation before at epsg.org. You can find it here: https://epsg.org/transformation_9940/DHDN-to-ETRS89-11.html. I am not sure if this is enough for sql-files. Maybe there is still a manual addition necessary

@ChristianMaierHVBG It seems you might be strugling with formatting of the readme ? For some reason, lines starting with *foo* should be terminated with 2 spaces. Anyway don't worry too much about that. We can fix that. The main thing to do at that point would be to add new lines in copyright_and_licenses.csv for the readme and the grid

Alright, we (my organization) decided to use the "Data licence Germany - attribution - version 2.0" aswell. I also modified the copyright_and_licenses.csv. Is there anything else I have to do now? Like you already mentioned, I am not really into GitHub, this is the first time I use it.

you probably forgot to git commit / push those changes

Is there anything else I have to do now?

that should be fine otherwise for this repository. In The OSGeo/PROJ repository, you also need to add a new line to link the .gsb grid name registerd in EPSG to the PROJ GeoTIFF one. Cf https://github.com/OSGeo/PROJ/blob/master/data/sql/grid_alternatives.sql#L99

Now it should be updated.
