Title
Bathymetric Survey 3-meter Depth Surfaces [Illinois--Cook County]
Description
The Cook County Bureau of Technology (BOT) and the U.S. Geological Survey (USGS) have collaborated on a comprehensive project to survey and map selected surface water bodies in Cook County, Illinois. This initiative addresses critical needs in surface-water and storm water management, emergency response, construction permitting, and aquatic habitat research. The carefully selected water bodies were surveyed based on size, accessibility, existing data availability, and current usage. The project involved collecting, processing, and analyzing bathymetric data and ancillary water-quality information. Notably, the collected data has been meticulously preprocessed into high-resolution lake polygons and detailed 2-foot interval contours. By combining cutting-edge data collection techniques with advanced preprocessing methods, this project sets a new standard for aquatic mapping in urban areas, ultimately contributing to more sustainable and effective water management practices in Cook County.
