8

I can define a custom CRS in QGIS (v2.18.13, Windows 8) and conversion works fine and no error is reported when I hit OK.

proj4 is +proj=lcc +lat_1=49 +lat_2=77 +lat_0=0 +lon_0=-95 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs +ellps=WGS84 +towgs84=0,0,0

Custom CRS dialogue

But when I go to use this CRS, there are no user-defined projections in the list.

Change CRS

A similar issue was raised here and here, but neither answer fixed my problem. May be a permissions issue, as the problem is not limited to the specific proj4 that I use, but I've enabled write access on all QGIS folder, still with no luck.

I'm experienced with GIS applications, but new to QGIS.

  • It works for me with QGIS 2.18.13. Menu for User defined CRS shows the new CRS as USER:100000 and all the parameters are there.

    Did you click on the plus button before OK?

  • Oh snap! Thanks @underdark. This was clearly not the intuitive order of operations to me! Works now. Thanks for all the comments. Oct 4, 2017 at 16:00

    I'm having the same issue in QGIS 3.10.0, but the plus button trick doesn't help.

As suggested above, you need to hit the plus sign after entering the proj4 information (not before). This was not at all intuitive to me, so I'll leave this (somewhat humbling) answer up here for others, in case I'm not the only outlier.

  • This should be marked as a fully valid answer!
