Abstract：
The tidal creek is the main channel for the interaction of the land-sea ecosystem. The morphological characteristics of tidal creeks have obvious temporal and spatial heterogeneity. Based on the Landsat TM/OLI satellite data of 20 scenes covering Yellow River Delta from 1998 to 2018 (cloud cover <10%), the tidal creeks of the study area were extracted using the accurate extraction algorithm of the tidal creek network in the heterogeneous background. After the tidal creeks were classified by the fast automatic classification algorithm of tidal creeks, the GIS spatial analysis function was used to extract the morphological characteristic parameters of the tidal creeks in the five-year study area, and the spatial-temporal dataset of tidal creek morphological characteristics in Yellow River Delta (1998-2018) was developed. The dataset is consisted of the following data: (1) the maximum extent of tidal flats; (2) spatial tidal creeks; (3) kernel density of tidal creek density; (4) kernel density of tidal creek bifurcation ratio; (5) over marsh path length data. Among them, the spatial resolution of the raster data is 30 m. The projection is WGS_1984_UTM_Zone_50N. The dataset is archived in .shp and .tif data formats, and consists of 120 data files with data size of 81.4 MB (compressed to 1 file with 14.8 MB). The analysis paper based on this dataset was published in Acta Geographica Sinica, Vol. 76, No. 9, 2021.Browse
