The following campus entities serve geospatial data at no charge.
Arthur Robinson Map Library - 310 Science Hall, 550 N Park St
The Arthur H. Robinson Map Library has an extensive collection of Wisconsin GIS data, acquired for use in research and teaching on the UW-Madison campus from various county government agencies. The Map Library also hosts a GIS and Geospatial Data Resource page, which contains links to various sources of international, federal, state, and local GIS data.

Applied Population Lab - 316 Agriculture Hall, 1450 Linden Dr
The Applied Population Lab (APL) is a group of research and outreach professionals located within the Department of Community and Environmental Sociology. The APL is widely respected throughout the United States for its strong research contributions in applied demography and small area population estimation and projections. In addition to consulting and direct client service, they provide online access to data through their WisStat and GetFacts applications, and serve as a State Data Center in Wisconsin.

Center for Sustainability & the Global Environment - 1710 Univ Ave
The Center for Sustainability and the Global Environment (SAGE) aims to improve our understanding of the global environment, and how it is being affected by human activities. To achieve this goal, they develop maps, computer models and datasets to describe the behavior of Earth’s terrestrial ecosystems, hydrological systems, and climate. These include a new generation of global ecosystem (IBIS) and terrestrial hydrology (THMB) models, as well as fully coupled climate-vegetation models (GENESIS-IBIS and CCM3-IBIS), and new datasets of global ecosystems, historical land use, and land cover change, datasets specific to the Amazon Basin.

Wisconsin Geologic & Natural History Survey - 3817 Mineral Point Rd
Staff at the Wisconsin Geologic and Natural History Survey (WGNHS) annually respond to more than 20,000 requests for information and assistance in the areas of geology, hydrology, minerals and mining, soils, biology, natural hazards, topographic maps, and other environmental and natural resource topics. They also provide digital datasets derived from published maps (original presentation scale: 1:100,000). Each dataset includes GIS data, metadata, a georeferenced image of the map as well as a PDF file of the map and any accompanying report.

In adddition to serving data, the UW campus maintains the state spatial data clearinghouse via the State Cartographer's Office in the Department of Geography.
WiscLinc: Statewide Spatial Data Clearinghouse
WiscLinc is a clearinghouse effort in Wisconsin maintained by the Wisconsin State Cartographer's Office. WiscLinc is part of a network of NSDI nodes which contribute to the progress of federal initatives such as Geospatial One-Stop and The National Map. WISCLINC pulls together records of geospatial data, land records websites and statewide land information inventory survey.
