This GIS dataset contains a modelled land mask for - 14m sea level low stand during Older Dryas , Europe area and also Younger Dryas, Mediterranean area based on global geoarchives. The sea level data was collected from data published in scholarly works (Lambeck2005, Fleming1998) and GIS proceeded with QGIS and ArcMap. Concerning the work flow GEBCO 2014 was used as raster data. Workflow: First of all the bounding box for GEBCO 2014 (30arc) raster data was set to 21.0_1.0_57.0_62.0 (CRC806 area) and interpolated using factor 0,1. Afterwards raster data was reclassified in order to get the specific elevation level that was mentioned in literature. The next steps were the vectorization of data and extraction of land mask followed by modification of attributes in adding sea level information to the dataset.
