I'm running a basic buffer tool on a polyline shapefile (teal line), to create a 50km buffer (beige) around it. However, ArcMap appears to only buffer part of the map (see image below).
How can this be worked around? Is the polyline too complicated?
I have already used the simplify line tool to try and speed up the process.
Storage type of buffer target: Shapefile
Co-ordinate system: WGS84
Co-ordinate resolution: Initially 1:250,000, but run under a 'Simplify Line' to a simplification tolerance of 0.5km
