I have a world map shapefile and I can only seem to get two results, both of which are half right.

The first, using a projection like EPSG:3857, I get a map that doesn't cut the east tip of Russia off, but does include a weird bar streaming across the whole earth:

On another projection, I get this, but with the Russia getting cut up problem (which I think looks a bit odd):

This seems to replicate no matter what Shapefile I use, so I'm guessing it's the projection?

there are two problems. Firstly (your first picture) the datasource (from this website esri) has some bad geometries some bad geometries

Secondly, some projections decided to draw from long -180°W to 180°E. so that's why russia is cut. It could be a result of a geopolitic conflict, but I really don"t know why they chose this line. If you need to get Russia "United" on a worldwide map, you can use Polar projection , but forget the south...

from polar projection

Project the earth is a set of compromises.

Some cartographers used a trick as you can see on this picture
the tricks enter image description here
(here earth has more than 360° ...)

  • That all makes sense. Thanks a ton for your help on this. Sep 26, 2017 at 12:01
