I'm trying to create a globe view in QGIS2.6 with an Azimuthal Orthographic projection using NaturalEarth's 110m countries dataset.
Using Hamish's recommended projection parameters with my lats/longs:
+proj=ortho +lat_0=36.5 +lon_0=-118.8 +x_0=0 +y_0=0 +a=6371000 +b=6371000 +units=m +no_defs to define a custom projection gives this result:
Lots of artefacts - what am I doing wrong / is it a bug?.
But Hamish mentions the presence of artefacts (I wouldn;t have thought the sort of artefacts i'm encountering but...) and recommends using some python to clip the dataset to the circle of the globe from the projection view.
I won't reproduce the python Hamish publishes (you can view it in step 2 in his post linked above) but having saved the file as
clipper.py in QGIS python path, imported into the QGIS python window (
import clipper) and done
clipper.doCall(iface,36.5,-118.8) I don't get a new layer generated in the map window.
How can I troubleshoot this? Are there any obvious things I might be doing wrong?
