#### PROCESSING ####
1. Polygon to raster (target attribute = "omschrijving") using existing DEM (AHN2) to snap the raster to (25m x 25m resolution)
* snap raster = all cells are designated to same geographical location

2. Raster to other format (.tif)

3. Change name from "paleogeografie[year]_PolygonToRaster.tif" to "paleogeografie[year]_25m.tif"

			* For 1250, 1500 and 1850 n.C maps, no occurances of "Stedelijk gebied" class, so "stedelijk gebied" was reclassified to
			"Bedijkte kwelders en riviervlakten", because almost all cities were on on riviervlakten (near rivers)
