Collection of lidar data in the St. Louis River Area of Concern in Wisconsin.


Ayres Associates will use the lidar point cloud to locate and compile culvert locations and elevations. The lidar data will be viewed in 3D to determine the lowest point where the culverts are located. Culvert lines will be compiled as breaklines to hydro enforce the digital elevation model (DEM). Ayres will use a one meter buffer around the compiled culvert lines for breakline proximity classification of lidar points.


Deliverable products will includes 1. A hydro-enforced project-wid DEM (ESRI floating point grid format) and 2. Culvert breaklines (shapefile format).
