LiDAR-derived vegetation now available

With the aid of the Southeastern Wisconsin Regional Planning Commission (SEWRPC), the MCLIO has recently finished processing the 2015 LiDAR flight to extract approximate canopy polygons. The ground-classified LAS files were further classified to deliniate vegetation points 8 ft tall or higher (but under 100 ft), and planar features such as building roofs were removed. The final product is available via Dropbox in a zipped file geodatabase. We recommend overlaying the vegetation polygons on top of our 2015 aerial photography! However, keep in mind that the data contains noise; some of the features mistakenly detected as vegetation (think semi trucks, electrical wires) based on height range alone will require manual processing to remove. We encourage you to download the data and let us know how you use and modify it for your needs.
