**topology errors:** Violations of the TNTmips vector topology, such as line elements with polygonal or planar topology that are missing nodes at the point of intersection, or polygons with polygonal topology that overlap without defining an intersection polygon. TNTmips processes that refer to the vector topology information either will not work, or will return erroneous results if the input vector object has topology errors.
