I had a great time this weekend at the 2nd annual Hack4Reno working on Open Data Reno, a hub to identify both available data pertinent to Reno and unfulfilled needs for data. The site is built on a WordPress theme started by Colin Loretz at last year’s hackathon, and this year I jumped in along with John Jusayan, Jeremy Murray, and Josh Infiesto to get it operational. I worked on improving the theme with Colin, and also locating and populating the site with data. In the process of doing that I learned more about a couple of useful sites for scraping, scrubbing, re-interfacing, and hosting difficult data sets. One is Cosm, where I found the most accessible air quality index data for Reno. The other is ScraperWiki, where I wrote a scraper to collect and present Reno water quality data from the very unstructured water authority lookup page. Fun!
