One of the first great topographic masterpieces in Europe was the Prussian topographic map Urmesstischblätter dating back to the years 1822–1876, composed of 3000 sheets. The aim of the study was to propose and test a method for handling single Urmesstischblätter sheets in terms of georeferencing the not fully cartometric sheets and fitting the map into a modern reference system with Qgis software. The raster images of the Urmesstischblätter maps had coordinates assigned to them, which was accomplished by fitting the images to the local coordinate system PL-1992 (EPSG:2180). In an attempt to minimise the distortions, i.e., to improve the cartometricity of the source images, an alternative method of georeferencing was proposed – namely, local georeferencing.polinfo:eu-repo/semantics/openAccesstopographic maps from XIX centurytransformation methodsgeoreferencingQgisArtykułhttps://doi.org/10.14746/bfg.2017.8.4
