The well-known Q/A-forum StackExchange has started a new “Open Data” section. Users can ask for needed datasets and get feedback from the great StackExchange community. Especially for our GIS and webmapping readers this is good news. Often the methodology isn’t the core problem of dealing with scientific or business issues. Often it’s more or less a lack of proper open datasets to run visualization and analyses.
The big advantage of StackExchange is their community with more than 5 million people. So if you have a current need for open datasets to populate your project idea, StackExchange OpenData is the right spot to ask for it.
