Add Buildings on Nonexistent Lots to QA #13

Closed mattyschell closed 1 year ago

You would think this was already included in the QA but no.

(motivation https://github.com/mattyschell/geodatabase-buildings-condoetl/issues/6)

We currently flag for QA buildings that do not touch their indicated tax lot. When a building's tax lot does not exist at all there is no spatial relationship to evaluate and these buildings are not flagged for for QA.

See this helpful list from @wmc281 where the most bad tax lots (from the perspective of matching mappluto) are building tax lots that do not exist.

Most of these are lots that have been dropped from the NYC tax map. The history of tax map changes can confirm. http://gis.nyc.gov/taxmap/history.htm
