Good point. It currently needs to be precomputed as images, so it's hard to make it customizable, but it probably makes sense to make a category of unsavory crimes. I would assume that most people dislike living near the same types of crime.

How are you precomputing the images? I thought GMaps provided a way to input data and get a heatmap, but apparently I'm mistaken.

They do if you're using Fusion Tables: http://code.google.com/apis/maps/documentation/javascript/ov...

Have you seen the one that plots crimes as if they were elevation? http://dougmccune.com/blog/2010/06/05/if-san-francisco-crime...

Very cool. Apparently prostitution is strikingly localized (which makes sense). It also seems that Hunters Point doesn't have much/any crime represented there either, yet it seems like people think of it as a very high crime area. I wonder why.

Sampling bias. The more people who visit a high-crime area, the more crime is likely to occur.

That and the gentrification resulting from UCSF's push into the area...

that is excellent. There's a 20 block area that is the reddest zone in the city and my guess is that's the Tenderloin. I wonder what impact an intense cleaning would have on the crime rate there. And enforcement of simple things like public urination laws. And maybe some decent bathrooms. I recall the kind of things New York did to restore a sense of order. Malcolm Gladwell talked about them in the Tipping Point. Sur…

Most definitely, but you'll never get a Rudy Giuliani figure elected as mayor of San Francisco, at least not in the foreseeable future.

My prediction: sometime in the next 30 years the tech industry will have drifted elsewhere, and San Franscisco will be the new Detroit. Right now it's a mixture of the sublime and the awful, but the sublime can always pack up and move to Portland/Austin/Seattle.

I can't be the only one who took one look at this and thought: Hey, that's SimCity! http://imgur.com/V2Bvo.png

That was my thought too - and I'd be curious to see something like SimCity's police station coverage map overlaid on this.

It amuses me to imagine the mayor's desk with a selection of these maps, plus a little R/C/I readout.

Most of what is sublime about San Francisco can't move.

But you're right. People in San Francisco don't seem to value public order enough to take the actions required to establish it.

This is very interesting. A friend of mine who lived on Frederick St, just a few blocks up the hill from Haight, said that crime was much lower on her block. Her theory was that bad guys didn't like to climb hills. And in fact there seems to be a correlation between altitude and crime rate. There are probably other reasons too. E.g. that the hills are fancier neighborhoods. But her explanation makes sense. If you're…

Shit rolls downhill.
