>>Charlotte,

>>We have updated our files based on your request.  Here is the 
>>response from our updating branch:
>>
>>"This request has been completed, and there are no more named S1740 
>>features (driveways) in Campbell, VA.  Those particular features 
>>either had the feature name removed, or the feature was deleted 
>>from the database altogether."
>>
>>This update will be reflected in our next release of the TIGER/Line 
>>shapefiles at the end of summer.

>>Anne,
>>
>>         After some communication with Campbell County officials 
>> about the named driveways issue, I received a reply from Dale 
>> Woods, their GIS director (see below), who says that the named 
>> driveways are not in their local data. I have passed this along to 
>> the OpenStreetMap US email list.
>>         I know that you will look into this, I would appreciate an 
>> update, even if it takes a long time, because it's a huge chore to 
>> change all those driveways manually. Maybe, if we know the details 
>> of the issue, our data guys can come up with some way to change 
>> the driveways en masse. OpenStreetMap also does imports of TIGER 
>> data about every other year to correct known issues.
>>         Thanks for your help.
>>
>>Best wishes,

>>         From your description, it sounds like you are looking at 
>> Census, TIGER
>>data.  Census adds these names to driveways, using the same name as the
>>road they come off of.  This is something Census does for their use.
>>Campbell County does NOT duplicate road names.
>>
>>Virginia has a statewide road database in which localities provide data
>>updates.  Campbell County participates in this process.  Statewide
>>street data can be viewed and/or downloaded from:

>>>Hello, TIGER staff,

>>>          I am a member of OpenStreetMap abd mpa mostly in the United

>>>perhaps, the GPS node of the house).
>>>          I have worked for the census, and I know how you gather

>>>neighborhood. However, this seems to be an issue with how the data is
>>>processed.
>>>          Are you working on something to correct this ongoing problem
>>>with driveway names?
