GIS reconstruction of the area surrounding the Grote or Zuidhollandse Waard near Dordrecht (Netherlands) prior to the St Elisabeth's Flood of 1421, which created a fresh water tidal area, the Biesbosch, which exists to this day. The GIS dataset accompanies a printed map and description, which is published in Tijdschrift Holland as part of the 600 year anniversary of the flood in 2021.
An explanation of how the reconstruction was made is available (in Dutch) in the above mentioned Tijdschrift Holland. A more substantial (English) data story or blog post is work in progress and can be found here. The GeoJSON files are available for wider use, and, in combination with the QGIS symbology files and/or the QGIS project file, are provided with build-in suggested visuals. For best results, store all files in one folder and open the project file in QGIS.
The reconstruction builds on the geographically more substantial dataset of local administrative boundaries in the Low Countries available here (version 7), which also provides the Codebook for this dataset.
