Yorkshire. My experience would lead me to say that a ground survey <br>
always overrules any such import. Do not be afraid to update the map <br>
data with what you actually find on the ground. There is no <br>
NaPTAN-sourced data structure that can be broken, it was imported and <br>
has been widely altered, added to and adjusted since. If a further <br>
NaPTAN import is made in an area it will have to be done in a way that <br>
respects surveyed data, which was much less of a problem in 2008.<br>
