Description: 2022 Cook County 1 ft. elevation contours for PLSS Township Area 29. Data is derived from 2022 lidar. If you plan on downloading this dataset it is recommended to use the File Geodatabase option. The shapefile format may not work for larger datasets. Abstract: One-foot interval contours are generated from a two-foot two-pass gridded surface created from the ground (class = 2) and road surface (class = 11) classified lidar points and the hydro breaklines. Purpose: This task is for providing a spring 2022 leaf-off and snow-free high-density lidar survey over an Area of Interest (AOI) of approximately 1,199 square miles covering Cook County, Illinois (and its surrounds).
