But that is a whole different ball game - we have to make sure our data is good quality, and I will need to think what to do when a bus turns off halfway along a road that is mapped as one line, for example, - and I’m not about to get into that for now! Although
I would like to, eventually!<o:p></o:p></span></p>

This is where having a unique ID for ab object comes into it's own. That<br>
is if the data source allows you to access that data using it. All that<br>
needs to be in the OSM data is 'bus stop' and it's NaPTAN reference, and<br>
anything else comes from a secondary read. Although names and the like<br>
may be worth duplicating.<br>
<br>
Where a source of a data import is readily accessible, then we don't<br>
need to duplicate the 'non-mapping' data. It may be for some imports we<br>
need a private copy of the data to make this work nicely, but that<br>
should be a natural part of the import process anyway. A clean copy of<br>
what was imported.<br>
<br>
What is available and easily accessible is growing daily ... but it does<br>
not need to be all imported into one database :)<br>
