This ticket is to distribute Swiss projection gridshift and associated init file.

The referenced NTv2 file was attached to the message this is a reply of:  http://lists.maptools.org/pipermail/proj/2012-February/006119.html the message was too big and was waiting for moderator to approve it. The file is also too big to attach here.

We're waiting for an official statement about distribution licensing. Alternatively we could use the one I derived which can be found here:  http://lists.maptools.org/pipermail/proj/2012-February/006093.html

I note that the CH file is using +towgs84 *and* +nadgrids, but there is no well defined behavior in such a case. I'd appreciate this not being done. Also, please add comments in the file indicating how it is intended to be used.

With regard to the grid shift file, can you not host it somewhere and add an http url? Are you waiting for a statement from me on the derived file? If the original file was ok to distribute, then a derived file should be. I don't recall if I checked the original file carefully with regard to distribution rights.

I didn't drop "+towgs84" due to the rumors that it may in the future be used for points outside the grid. No problem dropping it. I'm attaching a new version w/out it and with comments added.

It looks like swisstopo published the new gridshift file here:  http://www.swisstopo.admin.ch/internet/swisstopo/en/home/topics/survey/lv03-lv95/chenyx06/distortion_grids.html Direct url to the one we need:  http://www.swisstopo.admin.ch/internet/swisstopo/en/home/topics/survey/lv03-lv95/chenyx06/distortion_grids.parsys.65772.downloadList.15818.DownloadFile.tmp/chenyx06etrs.gsb

The notice on website says: "you can freely download it", doesn't mention redistribution

New version with comments and no +towgs84

Patch nad/Makefile.am and nad/Makefile.in to install nad/CH

Patch nad/Makefile.am and nad/Makefile.in to install nad/CH

[twpayne]

The CH file is not installed by make install. It has been added to the EXTRA_DIST variable in nad/Makefile.am and nad/Makefile.in, but should also have been added to the pkgdata_DATA variable. The attached patch fixes this.
