[OSGeo-Discuss] parcel data in US

[Emma Strong]

Oh my, that is quite an undertaking!!  Just in my little corner of the
States (south Mississippi) you're lucky if the county has parcels (or GIS
even), and then you're lucky if they will share it with you!  Many counties
in the area contract their parcel spatial management out to private
companies, and then they have to buy it back from them.

 Most of the counties in my state have at least CAD parcels, but then they
pay a third party contractor to convert that into a GIS file.  The US
Census has the best street and address data of the country, but they share
very little because of privacy laws.  Hopefully other states have better
data (and data management), but the only way I know to access parcels in
Mississippi is county by county (which unfortunately I have to do for my
job for 15 counties).

I know there are several counties in the country that have adopted a form
of Open Data standards, but still, it's county by county.  It may be easier
to narrow down your search area, especially if you need the most recent
public data.  Good luck!!
