This is a new visualization layer on PadMapper (an apartment hunting site) which shows the relative frequency of crime in different areas of San Francisco. It's not differentiated between nonviolent crime and violent crime currently (should be at some point). Red is bad, green is good, and nothing means very little crime reported for that area (even better than green within the bounds of SF, simply no data outside).

It would be nice if you could filter by the type of crime, not even necessarily violent crime. I might care if someone's selling heroin outside my door, or cars are being stolen, but probably wouldn't care if prostitutes are running about or dogs are unleashed.

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.

Wow, this is excellent. I'm looking at moving to San Francisco later this year and this is such important information. I knew that places like the Tenderloin were dangerous, but there's an unexpected hotspot in the middle of the Mission that I know to avoid now. Thanks.

That's an interesting feature for an apartment hunting site. However I think you have to add some information like the time-interval this goes back to. If it's only for a couple of days the statistic might be full of relative false-positives and false-negatives.

Personally, I'd be ok with pot and coke, but not heroin or meth.

Also, preferably decent-looking prostitutes, not any of those skeezy ones you see outside the 16th street BART.

Yeah, I think this needs a drugs checkbox selector widget, just like padmapper itself.

No luck getting the presidio data?

So most of Hunter's Point is crime free? Is this data correct?

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