John Merrill, Galileo Group, Inc., Director of Remote Sensing 20250411 Bloom_2024_Asphalt vector digital data This data is comprised of vector polygons which delineate areas of public road with an asphalt surface. Spectral and spatial analysis was conducted on airborne hyperspectral and LiDAR data to generate this layer. This vector data was created by Galileo Group Inc. for Cook County Illinois. It is comprised of vector polygons which delineate various roadway materials such as concrete and asphalt. It was derived from spectral and spatial analytics based on airborne hyperspectral and LiDAR data and publicly available roadway vectors from Cook County Illinois. 20250411 20250411 These vectors were dervied from Spring 2024 airborne hyperspectral imagery collected by Galileo Group Inc.
