Good Morning All, Many of you already know that LiDAR point clouds offer a unique opportunity to extract features such as building footprints via automated algorithms. If you want to learn more about how it is done the LiDAR Café republished an article on the subject. http://www.lidarnews.com/content/view/9130/136/ You won't be able to perform feature extraction from reading the article but it might shed some light and understanding of how it is done. Have a tremendous Tuesday!
