Especially if you can get access to the property, i.e. the owner has no
trespassing signs posted. Other tools such as QGIS and PostGIS come in
handy for getting your data ready for import.

Property lines also define the bounds of public areas like parks,
schoolyards, cemeteries, and airfields, which surely do belong in OSM. They
aren't infallible, but they are often more precise than guessing from
orthophotos. This has to be considered intermediate to advanced mapping,
since these features typically result from combining multiple lots, which
are often still separate in the tax rolls. Moreover, use of the property by
multiple agencies may have multiple land uses for a single tax parcel.
Still, it's a pretty good starting point. Even the fact that the tax rolls
identify a parcel as belonging to a government agency is an indication that
there is likely to be a mappable feature there.
