Regional and Local Sources
Often it is the case that national data does not provide geospatial data in units small enough for a local study. Such information is collected instead by state, regional, or county agencies. Contact a librarian for help identifying potential sources of information to answer your research question.

Minnesota Geospatial CommonsThe first stop for Minnesota data is the Minnesota Geospatial Commons. Nearly all of the data that the Minnesota Department of Natural Resources has published from the DNR Data Deli and DataFinder have migrated to a new home: the Minnesota Geospatial Commmons, a collaborative place for users and publishers of geospatial resources about Minnesota.

Minnesota Geographic Data ClearinghouseThis site offers many ways to access data, including the Minnesota GeoGateway, which simultaneously searches across agencies that distribute digital geographic data. Particularly helpful is a set of links to data organized by data theme (e.g. where to go for aerial photography or for soil data).
