Example of errors generated from the Polygons must not overlap with (#19) rule.Building footprints (in blue) must not overlap easements (in magenta).The violation areas are shown in yellow .The table shows the error report.User must make the decision whether these are:
--accuracy issues with one or other layer (more likely the footprint layer)--thus fix through editing.
--or violations where buildings have been built in easements--thus mark as “exceptions’
