一套高分辨率（1米）栅格格式土地利用数据产品，覆盖整个切萨皮克湾流域。该数据集基于2013–2014年高分辨率土地覆被数据集，并融合了包括分区规划、土地利用、地块边界、垃圾填埋场、洪泛区及湿地在内的13类辅助数据进行修正生成。其覆盖范围涵盖纽约州、宾夕法尼亚州、马里兰州、特拉华州、西弗吉尼亚州、弗吉尼亚州及哥伦比亚特区，总面积逾25万平方千米。该数据集由切萨皮克保护协会（Chesapeake Conservancy）下属的保护创新中心（Conservation Innovation Center）为切萨皮克湾计划（Chesapeake Bay Program）开发；后者是由美国环保局（EPA）牵头，联合其他联邦、州与地方政府机构、非营利组织及学术机构组成的区域协作伙伴关系，负责领导和协调切萨皮克湾修复工作。数据集在弗吉尼亚州划分为17类土地利用类型，在其余辖区则划分为16类。更多分类信息详见《土地利用类别说明》文档。影像数据以云优化GeoTIFF（Cloud-Optimized GeoTIFF, COG）格式存储。

A high-resolution 1-meter [land use data product](https://www.chesapeakeconservancy.org/conservation-innovation-center/high-resolution-data/land-use-data-project/) in raster format for the entire Chesapeake Bay watershed. The dataset was created by modifying the 2013-2014 high-resolution [land cover dataset](https://www.chesapeakeconservancy.org/conservation-innovation-center/high-resolution-data/land-cover-data-project/) using 13 ancillary datasets including data on zoning, land use, parcel boundaries, landfills, floodplains, and wetlands. The product area encompasses over 250,000 square kilometers in New York, Pennsylvania, Maryland, Delaware, West Virginia, Virginia, and the District of Columbia. The dataset was created by the [Chesapeake Conservancy](https://www.chesapeakeconservancy.org/) [Conservation Innovation Center](https://www.chesapeakeconservancy.org/conservation-innovation-center/) for the [Chesapeake Bay Program](https://www.chesapeakebay.net/), which is a regional partnership of EPA, other federal, state, and local agencies and governments, nonprofits, and academic institutions that leads and directs Chesapeake Bay restoration efforts. The dataset is composed of 17 land use classes in Virginia and 16 classes in all other jurisdictions. Additional information is available in a land use [Class Description](https://www.chesapeakeconservancy.org/wp-content/uploads/2018/11/2013-Phase-6-Mapped-Land-Use-Definitions-Updated-PC-11302018.pdf) document. Images are stored in [cloud-optimized GeoTIFF](https://www.cogeo.org/) format.
