<dd>Â Â Â Â Â Â Â Â Having been a Census-taker myself, I know the
process.<br>
<dd>Actually, it would be very unusual for an adress checker (done<br>
<dd>one year before the Census itself) to change a street name. We<br>
<dd>were given printouts that were our guide as we checked
addresses.<br>
<dd>If something didn't match, such as if a new apartment building<br>
<dd>was constructured, we had to do a special form. <br>
<dd>I never had a street-name change (Santa Monica is well-established),
<br>
<dd>but I imagine someone doing a suburban area might have some. <br>
<dd>Now, supposedly we got our information from someone who actually<br>
<dd>lives there. But, that means trusting that the person you are
talking<br>
<dd>to that day knows what they are talking about. So, there's lots of
<br>
<dd>room for error.<br>
<dd>In 2010, we were instructed to add a GPS point near the front
door<br>
<dd>of each dwelling unit or apartment building. However, we were
not<br>
<dd>given guidance on how close to stand. I suspect that is one
reason<br>
<dd>why we have so many zig-zag streets. :-)<br><br>

<dd>    After my inquiries about the
rash of named driveways in Campbell County, Virginia--these are driveways
that end of with the name of the street they intersect--I finally
got a reply from the county GIs director (pasted in below). He
says inequivocally that it is a TIGER issue, not a local one. Probably no
surprise. I know opinions vary on TIGER.<br><br>
</dl><br>
<dd>That's not a giant surprise. And it's not so much that
opinions on TIGER vary so much as the quality of TIGER itself is highly
variable. I've seen places where TIGER was amazing and there
wasn't much to do other than add speed limits and turn lanes.ÂÂ
But Portland, Oregon comes to mind as an area where it was pretty obvious
that they digitized someone's hand-drawn map, which was drawn on a napkin
with a fine-tip ballpoint pen in the rain, and was like trying to get a
cat to cooperate with being rubbed backwards to sanitize.<br>
<dd>Â
<dl>
<dd>    He also add a couple of data
souces, his own county and the state of Virginia, that could be useful.
<dd>    I sent this to TIGER and
asked that they update us on any fixes for this.<br><br>
</dl>
<dd>Â <br>
<dd>Given the inconsistency of TIGER data, I would not be surprised <br>
<dd>if no automated effort will be ever attempted to deal with that
dataset <br>
<dd>ever again.<br>
<dd>That said, there are tilesets out there that show TIGER data that
thas <br>
<dd>a newer name or geometry than what OSM has, though this itself has
its <br>
<dd>pitfalls. I've noticed a tendency for such datasets to false-positive
<br>
<dd>on a name because OklaDOT renamed something and whatever Census-<br>
<dd>taker mapped it in TIGER kept the old name.<br>
