This application includes a preliminary National Flood Hazard layer, preliminary changes since last flood insurance rates map (FIRM), preliminary map comparison tool, the pending National Flood Hazard layer, and the National Flood Hazard layer.

Federal agencies and their partners collect and manage large amounts of geospatial data - but these data are often not easily found when needed or accessible in useful forms. The Geospatial Platform provides ready access to federally maintained geospatial data, services and applications. The content of all datasets and services demarcated with the Data.gov globe have been verified by the Agency to be consistent with Federal privacy, national security, and information quality policies. As an additional service to our users, we also provide access to data from our partners across State, Tribal, Regional and local governments as well as non-governmental organizations.

The Lake & Flood Elevations Online (LFEO) viewer is a web-based interactive map tool for users to view flood elevations for lakes and other basins in Minnesota.

The DNR offers this wetland finder application that was "developed using the best available remote sensing data including high-resolution aerial imagery and lidar-based elevation models."

The Minnesota Well Index provides information about wells and borings in Minnesota. It provides basic information, such as location, depth, geology, construction and static water level, for many wells and borings drilled in Minnesota.

The National Elevation Dataset (NED) is the primary elevation data product of the USGS. The NED is a seamless dataset with the best available raster elevation data of the conterminous United States, Alaska, Hawaii, and territorial islands.

The Mission of NOAA's National Geodetic Survey (NGS) is "to define, maintain and provide access to the National Spatial Reference System to meet our nation's economic, social, and environmental needs."

This resource "provides tools for mapping and download of cancer statistics, risk factors, cancer related tobacco policy data, and the information related to geographic disparities in cancer."

The U.S. Fish and Wildlife Service offers wetlands mapper which "integrates digital map data along with other resource information to produce current information on the status, extent, characteristics and functions of wetlands, riparian , and deep-water habitats."

Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software.

The Census Bureau offers several file types and an application for mapping census geographic data based on data found in their MAF/TIGER database.
