Both the United States and Canada launched new data web portals this month.
Data.gov is the United States' new data website offering a limited number of datasets in a broad range of categories including: Energy and Utilities, Science and Technology, and Transportation among others. Two searchable catalogs are provided, a raw data catalog and a tools catalog with links to data mining tools. A video tutorial is available at http://www.data.gov/howtouse. You can also make recommendations for datasets that are not already included. To read the Whitehouse press release visit http://www.whitehouse.gov/blog/Democratizing-Data/
