Bathymetric Survey Shoreline Polygons

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.库克县技术局（Cook County Bureau of Technology, BOT）与美国地质调查局（U.S. Geological Survey, USGS）联合开展了一项综合性项目，对伊利诺伊州库克县内的选定地表水体开展勘测与制图工作。该项目可满足地表水资源与雨水管理、应急响应、建筑许可及水生栖息地研究等领域的关键需求。本次勘测的水体均经过严格遴选，遴选标准涵盖水体规模、可达性、现有数据可得性及当前使用场景。项目包含水深测量数据（bathymetric data）与配套水质信息的采集、处理与分析流程。值得关注的是，采集所得数据已经过精细预处理，生成了高分辨率湖泊多边形数据与详细的2英尺间隔等高线。本项目将前沿数据采集技术与先进预处理手段相结合，为城市区域水生测绘树立了全新行业标准，最终助力库克县实现更具可持续性与实效性的水资源管理实践。
