BIN list contains 82 entries - there are at least 200 buildings. COGIS inaccuracy also shown by “missing lot” buildings at left center. This problem also occurs frequently in new condominium developments.
Misalignment results in automatic matching with incorrect lot, frequently extending down entire block. In addition, polygons are missing for Central Park, JFK Airport, Flushing Meadows Park and perhaps other parks.
In addition to MTA yards and the airports, this is frequently found in Con Edison substations, parks, universities and hospitals.
Building covers (w to e) lots 76, 71, 66, 62, 60 and 51. All lots except 51 have “3000000” as BIN in GOAT.
There are many other GOAT BIN’s for which no buildings are found. PACS frequently lists these either as “vacant land”, or with buildings built early in the 20th century.
Many other bizarre shapes are found, occasionally with a BIN. Many other lots have been found in which the GOAT address entry obviously applies to a totally separate block.
The great majority of garages do not have their own BIN’s listed in GOAT. Occasionally, a group of garages with BIN’s is found, and the Douglaston area of Queens appears to be unique in that nearly every garage has its own BIN.
This PACS entry is obtained for a significant number of vacant lots. Perhaps 1800 is a default date?
Tempted as one might be to assert that God works in mysterious ways, further investigation reveals that PACS does not list the church as lot owner, and the church is not listed in the Manhattan telephone directory. It is therefore likely that this is an instance of Sanborn’s maps being out of date.
