Nicely done! This is a great idea! I hope those photos from the 30s
are digitized so they can receive the same treatment

From what I've seen of the 1930s/40s tax photos, they're much
better quality as far as framing. Not sure if this is the case
across the board, but the copies I looked up were pretty
consistently better. But you have to either go in to the
municipal building to look at them or order them online.

How appropriate. I was just watching Simon and Garfunkel perform
'The Boxer' in Central Park, 1981 on YouTube.

I don't know much about NYC, but I've read "The Bonfire of the
Vanities" (1987 novel; heard the movie sucked...). Anyone plot key
points in that? (for example: the car scene of Sherman and Maria,
the court house in the Bronx, the Park Avenue apartments). If not,

Seems that there would be quite a bit of historical value to
getting everyone to digitize their personal photos and upload them
to a shared repository. Has there already been such an effort?

In Detroit they collected family movies taken around the date of
the 1967 Detroit riots and created a movie.http://www.freep.com/s

Not that I know of. Without some way of knowing where and when
they're from, I'm not sure how useful the data would be. It'd
make an interesting project.During WWII the UK government (maybe
the US? I'm unable to find a reference but the search terms are
pretty generic) requested pictures and postcards from people
who'd taken recent trips into Europe. They wanted them for
intelligence reasons - I think it was the UK.That's the closest
thing I can think of, where there's been a request for massive
photos. They wanted people to include information about locations
and dates, as I recall.Someone here might be a historian and know
more details than I do.But, it seems like it'd be a large pile of
data and work. Unless they knew when and where they came from,
I'm not sure how much value they'd have - other than aesthetics.

Unless they knew when and where they came from, I'm not sure
how much value they'd have - other than aesthetics.You're
right, its a huge pile of work. Without the geotag and temporal
EXIF data, you're relying on machine vision/structure from
motion (think https://mapillary.com) to rebuild 3D scenes
solely from image data.https://help.mapillary.com/hc/en-
us/articles/115001770329-Ma..."Mapillary uses a technology
called Structure from Motion (SfM) to create and reconstruct
places in 3D. By matching points between different images, SfM
is able to locate the point in a three-dimensional space and
therefore determine its location on the map. The more images
there are available for a specific point, the more accurately
it can be reconstructed. In addition, SfM creates the kind of
smooth transitions between images that you can see in the
Mapillary viewer?again, provided that images have been taken
within close proximity with enough overlap between them.We also
run semantic segmentation on the images. This means that the
computer tries to understand what is in the image and assigns a
category tag to each pixel. That enables us to detect different
areas in the images (such as buildings, pedestrians, cars
etc.). Semantic segmentation together with 3D reconstruction
enables us to extract 3D positions of objects such as traffic
signs and display them on the map. You can get more detailed
information on what is currently available on our product
page."Disclaimer: No relation, just dig their tech (they're
using machine vision to build world models for self-driving
cars, using crowd sourced imagery).

When I typed my reply, I briefly considered if AI/ML/NN might
help but then I thought about it. I don't think there will be
enough training data and I suspect that existing reference
points would be vastly different, and made even more
difficult to use by the lack of resolution.But... If it had
some initial training done by hand, and by people including
what dates and locations they know, maybe it could work
backwards? It'd still end up being a HUGE amount of data and
the compute power for that would probably be obscene.Which,
of course, means I think it's an excellent idea and that
someone should do this. I can't even begin to imagine the
costs. This might just be the best idea ever, or the worst.
toomuchtodo - 3 hours ago
Sounds like fun! I know the Mapillary folks from
interviewing with them. I think it'd just be a matter of me
paying for the spot instances for the compute time. I'm
going to ask!
KGIII - 2 hours ago
And the data acquisition.It does tie into a strange idea
that I've been tossing about for the past decade.A
cluster of used cell phones. They're easy to power,
probably free for the taking, and might make for big
computing while just using something that'd normally be
thrown away.My original idea was SETI or one of the
unfolding@home type projects, but something like this
might make for a good project.Alas, I'm way too lazy (and
not qualified) to do this. Laziness is one of the perks

This is similar to this one for SF http://www.oldsf.org/Looks
like the NYC one has more coverage though.

The South Bronx really was a war-zone.http://80s.nyc/#show/40.8265/
those rent-control incentivized arsons... empty lots with garbage
everywhere... dogs running around with no owners visible.Edit:
correction, while rent-control played a big role in Brooklyn's
housing abandonment rate, South Bronx faced a variety of factors in
addition to rent control:> For example, housing abandonment in the
South Bronx, probably the most devastated area in the entire city,
can be plausibly related to the economics of an obsolete housing
stock. The area was one of the most densely populated in the
country in the 1940s and 1950s, and the housing stock consists
almost entirely of five- and six-story walkups. As population
density decreased, fifth- and sixth-story walkup apartments became
unrentable at prices sufficient for sound building maintenance,
irrespective of rent controls. Arson eventually became the owners'
only financially rewarding alternative.http://www.crainsnewyork.com

Another perspective on the rash of South Bronx arsons is that it
was caused by bad data science. See story here:
dmix - 2 hours ago
Thanks, I came across that article too. I've included an edit,
there were many factors involved in the South Bronx blight
(economic and political), but yes fire stations shutting down
in neighbourhoods with less political pull was certainly one of
them.The fires ended up ruining entire neighbourhoods due to
the poor city response times, but the simple fact is many of
them were started due to landlord arson or from poor property
maintenance by the owners.

The incentives weren't just rent control but also white-
flight population decline leading to decreased rent rolls
leading to reduced property valuations that weren't yet
reflected in insurance valuations.And much of that white
flight was due to the Federal government funding interstates
to the suburbs and subsidizing mortgage loans for whites only
that made suburban houses cheaper for white middle-class
families to live in than urban apartments.
Redl...The South Bronx was also entirely redlined by the HOLC
in the 1930s, rendering it ineligible for mortgage loans for

> And much of that white flight was due to the Federal
government funding interstates to the suburbs and
subsidizing mortgage loans for whites only that made
suburban houses cheaper for white middle-class families to
live in than urban apartments. .That study is for
"1934?1968". The civil rights act (1969) made that type of
discrimination illegal and included provisions to
incentivize the reduction of segregation, yet I've read
that nearly 50yrs later housing segregation is still today
higher (or as high) than before the civil rights act.I'm
sure that federal policy played a big role in white flight
but I'm curious why it hasn't reversed despite these
changes... there must be other forces still at play here,
that or we're seeing a multi-generational side-effect of
bad policy.But regardless it's interesting to think that so
much government policy did the exact opposite of help the
poor at federal, state, and city level... from city
budgeting of fire stations to mortgage incentives to rent
control and zoning laws, etc.

One of the most stunning parts of the movie Koyaanisqatsi are the
demolition of builds in the South Bronx (I'm pretty sure they're
there, can someone confirm?). And, the scenes from the movie
Wolfen look very similar to the above scenes.

From having browsed through the tax lot photos in the municipal
archives from prior generations, it would be fun to see a split
view where you browse around both the 1940s and 1980s at the same
time.If you browse around 80s Williamsburg photos it is not a place
you would want to be. Now every one of those lots would be a
minimum of $1M, with waterfront lots in the tens of millions. Pays
to play the long game.
