The Humanitarian Data Exchange is doing great work and they have a well defined road map they are plugging away at.
The sub-national time series dataset hosted there is the first data feed I am using to test EbolaMapper against.
They have a very nice, interactive ebola dashboard. The story of how the dashboard came to be is impressive but I want to work to make that tortured path not have to be traveled for future outbreaks.
They do not have case mapped to locations over time. For that The New York Times is the best.
