The digital storage system doesn't know whether the legal authorities meant to define a geodesic, rhumb line or a y=ax+b line in the national projected CRS (RD) for a policy or a zoning border. To avoid this problem, it is more safe to force the legal authorities to be specific, without having to explain them the difference between a geodesic, rhumb line, projections etc.
