The Wisconsin State Cartographer’s Office is making available LiDAR derived DEMs for the state of Wisconsin. As of now 14 of 72 counties are available with 7 more coming in the next few months and other counties are planned after that. The website is WisconsinView. Here is all the data available besides the LiDAR DEMs and and how to download data.
Besides the LiDAR DEMs Emergency Managers and Meteorologists would be interested in flooding and tornado damage imagery and vector data.
