I am trying to import the ne_10m_admin_0_countries shp file from Natural Earth into TileMill but I get strange map tearing around Antarctica.
I tried through PostGIS first (my main motivation for using this dataset) but later experimented and just tried to import the shp file directly with the same result.
Does anyone have an idea what is going on and how to fix it?
This is with TileMills default country layer:
With the ne_10m_admin_0_countries shp file:
and with both of the layers showing:
(edit from comments below) The data looks fine in QGIS:
(2nd edit) It seems to come down to the following 2 points on Antarctica, but I am unsure how to fix it. I've increased the line-width to make the problem more clear.
Northern / left problem point (zoom 10):
Southern / right problem point (zoom 10):
(3rd edit) Okay so I tried reprojecting it from QGIS which just lead to QGIS crashing when I tried to save the shape file. I was trying to reproject it into EPSG:3857 / 900913:
+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0.0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs +over
However I was able to get QGIS to do on the fly reprojection to EPSG:3857 and that also looks a bit strange:
