I am trying to define a custom CRS in QGIS 3.4 to work on some data in Central Asia. I want to use the
Albers Equal Area Conic but change the parameters so that the transformation works best for my study area.
I first tried to go via "Settings" --> "Custom CRS". I defined the name and the
+proj=aea +lat_1=21 +lat_2=49 +lat_0=37 +lon_0=87 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs. But when I click "Ok", nothing happens.
I don't get an error message or any feedback, there's just no response. (I tried QGIS 3.10 as well, but the same problem occurred.) This looks like a bug to me or is there something I missed?
If this cannot be reproduced, I could also go the Python way, but I'm not so familiar with that. I've read through some documentation and found the following pieces of code but I'm not sure if they are in the right order or if something is missing:
my_crs = QgsCoordinateReferenceSystem() my_crs.createFromProj4("+proj=aea +lat_1=21 +lat_2=49 +lat_0=37 +lon_0=87 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs") my_crs.saveAsUserCrs("Albers_Central_Asia")
