itwbennett writes "The New York City Health Department's Rat Information Portal provides raw data on where the rats are, based on inspections done by the health department, as well as by their rat indexing initiative. The portal isn't a new open data initiative, but if you're a NYC resident and not a big fan of rodents, the site is worth a look. 'The most interesting part of the portal is the interactive heat map of rat inspection data,' says ITworld's Phil Johnson. 'Using this interactive map, you can look up the inspection history, going back to 2009, for any address in the five boroughs. It will tell you the dates and results of any inspections, as well of any follow up compliance checks. As for raw data, the site provides city-wide rat reports, aggregated to the zip code level, going back to 2006.'"
