Comprehensive bathymetry and intertidal topography of the Amazon estuary

This dataset contains the following maps: 1) Bathymetry of the Amazon estuary (Bathymetry.tif and Bathymetry.nc); Elevation in meters relative to the EGM2008 geoid. 2) Topography of the non-forested portion of the lower Amazon floodplain (Topography.tif and Topography.nc); Elevation in meters relative to the EGM2008 geoid. 3) Flood frequency for the period 2015 to 2018 (FloodFrequency_15to18.tif and FloodFrequency_15to18.nc); Values ranging from 0 to 100%. 4) Unified mapping of the Amazon estuary: merge of bathymetry, topography, MERIT, and GEBCO products (DEM_AMestuary.tif and DEM_AMestuary.nc); Elevation in meters relative to the EGM2008 geoid. 5) Boundaries of each domain of the unified mapping (domain_boundary.shp). 6) Code example to read netcdf files in MATLAB (read_netcdf.m).

本数据集包含以下地理空间数据：1) 亚马逊河口水深数据（Bathymetry.tif 与 Bathymetry.nc）：数据为相对于EGM2008大地水准面的高程，单位为米。2) 亚马逊下游泛滥平原非林区地形数据（Topography.tif 与 Topography.nc）：数据为相对于EGM2008大地水准面的高程，单位为米。3) 2015年至2018年洪水频率数据（FloodFrequency_15to18.tif 与 FloodFrequency_15to18.nc）：数值取值范围为0至100%。4) 亚马逊河口统一制图数据（DEM_AMestuary.tif 与 DEM_AMestuary.nc）：由水深、地形、MERIT及GEBCO产品合并生成，数据为相对于EGM2008大地水准面的高程，单位为米。5) 统一制图各区域的边界数据（domain_boundary.shp）。6) MATLAB环境下读取网络通用数据格式（NetCDF）文件的代码示例（read_netcdf.m）。
