For a single county or jurisdiction, if you delete the TIGER data and import more accurate local data, what do you do at the boundaries? County/Stare data sets I've seen usually get cut off +/- a few hundred feet (if that) from the boundary. Does somebody go through and make them fit/connect

Dan, Alexandria gave us permission to import their data but still wanted the 100 dollar CD fee. Someone paid that and we do have the data. As far as I know nobody has asked Fairfax County, but I figured making D.C. look nice with a combination of mapping and importing would be a strong tool

Hi Kate, Sounds good. My guess is that the data from the District is based on the assessor parcels. Given what you said (I'm assuming you are in the Northern VA suburbs of DC), have you looked into whether Fairfax County or Alexandria has released their parcel or centerline road data? Dan On Sun

Hi Dan, Both manual and donated data. I've been addressing my neighborhood in Virginia but Washington D.C. donated point level addresses. Kate Chapman On Nov 15, 2009, at 6:37 PM, Dan Putler wrote: > Hi Kate, > > How have the address points been obtained? From OSM users? The Census > Bure

Hi Kate, How have the address points been obtained? From OSM users? The Census Bureau has collected and created a national data set of them in preparation for the 2010 Census, but for non-disclosure reasons, they have no intention of releasing them to the public. The next possible public source of

Dave, Understood, I would envision it being a partially manual and partially automated process. Maybe I'm confused about the address versus road information. I would think the address point would be the front door of the building and would not be a relation to the road. So the node of the addre

Kate, Nothing at all. The thing is that in many instances the road vectors, and the address ranges, may well be more accurate in data from the county than from TIGER data. The Census Bureau has done some things to clean up what there road vectors, but for some counties I've looked at, there is sti

Dan, What's wrong with doing automated addressing imports in situations where we have point level address data? Or are you just referring to not importing the addressing that is available for the Tiger data? Kate Chapman On Sun, Nov 15, 2009 at 6:00 PM, Dave Hansen wrote: > On Sun, 2009-11-1
