A shapefile is capable of representing features on the ground to within a centimetre of precision. Disagreements between two spatial data sets that claim to represent the same entity may occur for several reasons. Representing a curved border with centimetre precision requires a lot of points along the border. This makes your data set very very large. In ...

Shapefiles utilize IEEE 64-bit floating-point representation to store coordinates. They have a precision of at least micrometres at the Equator and 180th meridian using decimal degrees, far in excess of the capabilities of geodata collection.
