- **Gauss-Krüger**: this is similar to UTM and widely used in Germany, but is being superseded by UTM.
- **From Proj.4 specification**: projections are internally handled by the [PROJ.4 Cartographic Projections library](https://proj4.org/), so coordinate reference systems can also be given in its internal specification format. Examples may be found at [http://www.remotesensing.org/geotiff/proj_list/ (Internet Archive)](https://web.archive.org/web/20160802172057/http://www.remotesensing.org/geotiff/proj_list/) and [http://spatialreference.org/](http://spatialreference.org/). When selecting this option, the specification field will be pre-filled with the specification of the previously selected coordinate reference system.

Um, oh. We are not using the current release of it, but we should probably replace "Proj.4" with "PROJ" everywhere.

I merge as is now because the app isn't updated yet.
