The news for today: My two Philadelphia crime sites, Philly Rap Sheet and Philly Crime Map, are joining together in a way that enriches both and will make Philly Crime Map considerably more powerful in the near future.
From an e-mail I sent to select users:
Wanted to let you know that I've begun the process of linking together Philly Rap Sheet's arrest data and Philly Crime Map's location information, greatly enriching the police department's Part One Crime Incidents dump.
The result: You can now see who was arrested when you look up new incidents on Philly Crime Map, and certain entries on Philly Rap Sheet are now geotagged (example here).
What is now a simple linkage will soon grow, enabling users to search by demographic on Philly Crime Map as you're currently able to do on Rap Sheet. I'm hoping within the next month that you'll be able to see the geographic distribution of crimes committed by 21-year-olds, or the arrests by a certain officer at night, or the string of crimes committed by a single person over two years.
I'm also working to speed up Philly Crime Map's searches, which have gotten a bit creaky with the half-million crime incidents it currently catalogs.
