FRACTIONAL IMPERVIOUS SURFACE 1985-2025 NBEP2026 (excel)

This excel contains impervious cover results for the Narragansett Bay Estuary Program's Status and Trends Report (nbep.org). Impervious cover was analyzed using the U.S. Geological Survey's Annual National Land Cover Database Fractional Impervious Surface rasters. Results presented include the area and percent area of impervious cover for various geoscales. The methods used to produce this dataset can be found at https://github.com/nbep/st-impervious本Excel文件包含纳拉甘西特湾河口项目（Narragansett Bay Estuary Program, nbep.org）《现状与趋势报告》的不透水面覆盖率相关结果。不透水面覆盖率的分析基于美国地质调查局（U.S. Geological Survey）发布的年度全国土地覆盖数据库（Annual National Land Cover Database）百分比不透水面栅格（Fractional Impervious Surface rasters）数据开展。本次公开的结果涵盖了不同地理尺度下的不透水面覆盖面积及其占比。本数据集的制作方法可通过链接 https://github.com/nbep/st-impervious 查阅。
