John Merrill, Galileo Group, Inc., Director of Remote Sensing 20251002 Palos_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. 20251002 Derived from 2024 hyperspectral imagery Complete None planned -87.914718 -87.795367 41.733916 41.643459 ISO 19115 Topic Categories transportation None Derived from 2024 hyperspectral imagery None None Galileo Group Inc.
