<div>I'm wondering what the proper way to create an adjacent area is. For example <a href="http://www.openstreetmap.org/?lat=6.805586&lon=-58.161404&zoom=18&layers=M" target="_blank">here</a> there's a prison that takes up a full city block. Does one draw a square using the same 4 existing nodes from the intersections around it? Or should one zoom in and put 4 new nodes close to the existing ones?</div>
</blockquote></div><br>New nodes are preferable. The roads are lines in DP, but have a width in reality. Thus, the prison doesn´t really start where the line is, which is the center of the road, but on the side of it. Even if you choose to portray it as such (for example, because you don't want the part between the prison and the road to be specified as something else than prison, because it's not really residential area, and it's strange to have a hole in the residential area here and not for other roads), it is still better to use separate points, so that the next person, if they choose to make a more precise mapping of the prison walls, can move the points rather than having to create new ones.<br clear="all">
