[OHM] historic NYC buildings

[Susanna Ånäs]

The Helsinki one from last June was based on a readily opened file, that is
linked to this post
http://www.hri.fi/fi/sovellukset/helsinki-by-age/

The buildings file was an effort by the city of Helsinki, cleaning and
combining different datasets. I had used it earlier for georeferencing in
QGIS. Filtering it to show only buildings that existed at the date of the
map.

There's also one for Brooklyn only
http://bklynr.com/block-by-block-brooklyns-past-and-present/.

I've been ordered curtains and T-shirts. I think I will eventually make
some of those :-D
