I'm making a range map for Proteus anguinus
using NaturalEarth vector for countries and a vector layer of the olm's range from the IUCN. The problem is that although both layers are in GCS_WGS_1984 coordinate system, they do not overlay perfectly (see below).
I reckon this is a common issue when working with data from different sources - some are more precise than others ... so what do you usually do in such cases? Manually edit one feature so it matches the other?
