I'm trying to create a globe view in QGIS 3.16.1 with an Azimuthal Orthographic projection. This is my projection codes:
+proj=ortho +lat_0=32.4279 +lon_0=53.688 +x_0=0 +y_0=0 +R=6371000 +units=m +no_defs +type=crs
After the new projection are defined and there was no error, after applying this new projection, my map does not appear spherical (globe veiw). What is the problem?
Here's how I've done this.
First start QGIS and load Natural Earth coastline data. The coordinates in this data are lat-long EPSG:4326. It looks like this:
because the coordinate system for the project is:
set in the bottom right control.
Now I do "Settings, Custom Projections" and add yours:
And I click the "Validate" button and its all good. Back to the map and nothing has changed.
Click on the "EPSG:4326" button at bottom right and find that new coordinate system in the "Predefined Coordinate Reference System" list:
you can see it as "SO Question" and it has a code of "USER:100043" - your code will be different. Select that, select "Apply" and return to the map and:
an earth sphere view. (Note I've done coastlines here not polygons). The project coordinate reference bottom right now shows:
that I am using that custom projection. I can switch this back to epsg:4326 if I want to get back to that projection in my map.
