I would be very careful in using this. Is this really "south" e.g.<br>
180° ? Or is it more like 99° ? Or 269° ?<br>
<br>
Most streets are not strictly on the 90° raster and signposts are<br>
only rough directions.<br>
<br>
Addings this to OSM might make it much more difficult for Data Consumers<br>
to process and interpret data.</blockquote><div><br></div><div>No, these aren't compass directions. They're the directionality of the road. For example, this way is part of the I-94 interstate going west, but a compass in a car driving on it would tell the viewer they were pointing north:</div>
