buildings with a way. We really should be discouraging people mapping<br>
as nodes like this as it is largely a waste of time since someone has to<br>
map it as a way later on anyway and when they do they either need to<br>
delete the existing nodes or merge them into the buildings to preserve<br>
history (but also taking much longer).<br>
<br>
Adding renderings to maps only encourages people to take the easy way<br>
out in the short term and create more bad data. We should not encourage<br>
this and should be actively trying to fix the nodes already in the<br>
database. I have done this on a few occasions and have probably knocked<br>
out a few thousand of them, but unless we get serious about cleaning<br>
them up we will end up with more and more of them.<br>
<br>
Buildings as nodes is not a recognized way of mapping them that has<br>
broad support. Almost without exception the only people doing this are<br>
newbie HOT mappers who don't know the correct procedure. So this is a<br>
mistake that should be fixed, just like non-square buildings or<br>
unconnected roads.<br>
