Data associated with the article "Satellite-derived Trends in Inundation Frequency Reveal the Fate of Saltmarshes”

In the publication associated with this dataset we retrieve inundation frequency change in different tidal basins over 27 years using satellite data from the entire Landsat 5 TM dataset. The method to retrieve inundation frequency is applied in Google Earth Engine (GEE). We further retrieve habitat change from the same satellite dataset and investigate how changes in inundation frequency affect saltmarsh development. In this dataset we provide time series of mean inundation frequency over the respective tidal basin; time series of habitat change; the GEE scripts which generate those time series; a pixelwise comparison of generated inundation frequency with another published inundation frequency and an elevation dataset of the same basin, as well as the GEE scripts generating this pixelwise comparison; generated maps of significant inundation frequency change between 1986 and 2010; and generated habitat classification (saltmarsh, tidal flats, water) maps from 1986 and 2010.

本数据集关联的学术研究中，研究团队基于完整的陆地卫星5号专题制图仪（Landsat 5 TM）数据集，利用卫星遥感数据获取了27年间不同潮汐盆地的淹没频率变化。相关淹没频率的提取方法在谷歌地球引擎（Google Earth Engine，GEE）中完成实现。研究团队进一步依托同一卫星数据集提取了栖息地变化信息，并探究了淹没频率变化对盐沼发育的影响。本数据集包含以下内容：各对应潮汐盆地的平均淹没频率时间序列、栖息地变化时间序列；用于生成上述两类时间序列的GEE脚本；将本研究提取得到的淹没频率与另一已发表的淹没频率数据及对应盆地的高程数据集进行逐像素对比的结果，以及实现该逐像素对比的GEE脚本；1986年至2010年间显著淹没频率变化的生成地图；以及基于1986年与2010年影像生成的栖息地分类（盐沼、潮间带滩涂、水体）地图。
