SafemapTecnolgs··on Show HN: Play with an interactive heatmap of SF crime (and other cities)
Thanks. Yeah, we noticed this too. It seems to be just a strange quirk of the SF dataset, and only in the Richmond / Sunset districts. Or who knows, maybe it is true.

Thank you for the great suggestions. You've given us a lot of great ideas to think about. Much appreciated!!!

Hey Josh! I was wondering whether you'd see this! Thanks for checking out the site - we'd love to expand to the UK and to add an API, thanks for the ideas.

It was great meeting you and chatting with you on that bus ride, hope you folks had a nice rest of your trip! And hope things are going well with LoginLlama and the other cloud storage related project you were talking about. Let me know if you ever need some beta testing done or something like that :)

Thank you for helping to resolve the situation! Please disregard the email reply I sent as the issue was clearly rectified.

@dang or other HN mods - can you help me understand why this post was so rapidly downranked? It's now on the 6th page... it's got to be the highest upvoted yet lowest ranked post submitted today. As far as I can tell there were no flags or anything. Am I missing something here?

Thanks! Yeah unfortunately with cities like SF nowhere is truly "safe to park" but hopefully this helps people avoid the major hotspots!

Interesting, thanks for the info. I think it hopefully should be OK for the currently supported cities. Lots of cities have 0,0 as the geo point for crimes without points, which we filter out. For others such as SF, it looks like the police HQ is in Mission Bay which doesn't seem to have a high crime rate for any category. This info would also hopefully be included in the dataset disclaimers, and we didn't see this in any of the datasets we use.

But thanks for the info, this is great to know for any potential future expansions. If you see any cases where this might be happening for the currently supported cities, please don't hesitate to get into contact with us :)

Public datasets. You can view the sources for each city by expanding the "Data Sources" tab in the sidebar menu.

Stay tuned for some exciting feature launches in the near future :)

Thank you! We are definitely interested in expanding to as many cities and countries as possible. We focused on large US cities with good datasets for this MVP, but depending on how things go, we will hopefully be expanding to cities across the world very soon.

Hmm, thanks. Hopefully this doesn't include the map itself. Would you kindly provide the browser / OS combo you are operating? Will try and look into this.

Thanks! Yeah, we definitely plan to add long term historical data and give users the option of diving deeper into the trends. Should be in the very near future. Thanks for the idea of auto-hiding the sidebar on a map click - that's very intuitive. Will probably push an update later today to add this.

Thanks for checking out the site and for the feedback. It's definitely something we're looking into.

It's kind of an interesting question though because it somewhat varies by crime category. Take car break ins, for instance - this is more of a constant factor than a population density scalar because the number of parking spots is generally fixed on a per-block basis rather than scaling with population density.

I think we might try to give users the option of dividing by population density but allow them to toggle this on/off.
