This is a really good site for individuals wanting to do county wide and vegetation LiDAR projects. Sonoma County, California is working on a multi-use LiDAR collection for the county and this site represents the work they are doing to develop the program. This is a great example of how to get a program together to use LiDAR in as many ways possible and extend the usability of the data. There is some very good presentations on LiDAR in the LiDAR forum Link on the site. Click on the link below
