Spatial Data Resources
The Big Ten Academic Alliance Geoportal provides discoverability and facilitates access to geospatial resources. The resources in the portal are selected and curated by librarians and geospatial specialists at ten research institutions in the Big Ten Academic Alliance.
The resources include GIS datasets, web services, and digitized historical maps.
The Open Geoportal (OGP) is a collaboratively developed, open source, federated web application framework to rapidly discover, preview and retrieve geospatial data from multiple repositories. The Open Geoportal Federation is a community of geospatial professionals, developers, information architects, librarians, metadata specialists and enthusiasts working together to make geospatial data and maps available on the web and contribute to global spatial data infrastructure.
