The document summarizes Minnesota's elevation mapping project. It began in the 2000s with small, non-coordinated projects producing proprietary data. In 2006, funding supported a cooperative project, and a committee was formed to build a statewide high-accuracy DEM. Major flooding in 2007 helped secure funding. The Clean Water Legacy Fund now supports collecting LiDAR data for 40,000 square miles through 2019. The project specifications closely follow USGS standards, and data will be publicly available through web services and other delivery methods. Partnerships across government levels help maximize resources for the project.
