Global Wildlife Disease News Map Version 2

USGS and partners launched Global Wildlife Disease News Map Version 2 back in March; version 1 was out last December. To be clear this is a news map (Google Map mashup), not a map of disease, but a map of news on disease. So, when you "turn on" avian flu, you get a hit in Ohio. Strange, I thought, didn't hear about that. Of course not! The article in the local paper was about how cows tested negative.

Even though I read the title with "news" in it several times, I kept thinking this was a map of spread. The other disappointment is that all news is tagged with point markers color coded to geographic level. Different colored "tears" mean: Place, County, Administrative Unit, Country, Continent. While I know creating meaningful polygons is a challenge, I found this confusing. I'd prefer they not symbolize for geographic level and let users explore that when they mouse over, more like MetaCarta's GeoSearch News.

Details of how the app works are here. In the works: search by date range, user generated filters (queries I guess), more historic data, extraction of text.
