<body><div>Very true Mike. There is still some value in detecting TIGER roads that are in 'original' state. For example, if you can detect a cluster of 'unmodified' TIGER roads, that would point to an area entirely untouched by human editors.<br></div>
<div><br></div>
<div>I write 'original' and 'unmodified' in quotes, because a number of bots have touched most TIGER imported ways, so TIGER ways having version=1 are rare.<br></div>

<div><div> As long as there is at least one tag left that would indicate TIGER as the original source, so we can continue to detect 'unmodified TIGER' roads.<br></div>

</blockquote><div>Just because a TIGER road has been modified doesn't mean it has been verified, for example if you add a side street you will probably have to add a shared node at its intersection with the road in question, and that would bump the version - meaning it is now "modified" even though the mapper may not have reviewed the entire length of the TIGER road. Conversely, just because a TIGER road is still at version 0, doesn't mean it hasn't been verified as existing nodes that make up the way can be moved without bumping the version on the way. <br></div>
