Interactive visualisation of historical and prehistoric sea levels over a DEM
About
Sea Level Slider adds a dockable slider that shows how a digital elevation model (DEM) would be submerged at a given historical/prehistoric sea level, for shoreline-displacement ("strandlinje") studies used in Norwegian archaeology to model land uplift and predict coastal site locations since the last ice age. Ported from an ArcGIS Pro script (arcpy, Con + RasterToPolygon over a DEM, 1-220 m range) drafted by Steinar Kristensen at the Museum of Cultural History, University of Oslo.
