Overlay maps
The existing maps have not only been digitized and contextualized in the course of the
project „Austrian Dialect Cartography 1924-1956. Digitalization, Contextualization,
Visualization.“ but – as is evident by the project’s name – they have also been
visualized. This means that certain maps have been georeferenced completely.
Georeferencing is the addition of spatial information to a set of data. In our case,
this means that the historical maps in our collection are enriched with current
geographical data, facilitating a comparison between historical and contemporary
geographical spaces and or/their representation.
The georeferencing was carried out with the help of the open source program QGIS3.
Following on from this, the next step was visualization. The application in which the
georeferenced maps are displayed allows users to choose which map to view in the
context of a particular type of visualization – for example, overlaid on top of Google
Maps. Users can adjust the degree of transparency for the historical map to better
comprehend its relations to the present-day cartographical visualization.
We divide the georeferenced maps into two groups: First, we chose maps with a relation
to geopolitics, persuasive cartography (propaganda cartography) and cultural geography.
Secondly, we chose maps assigned to the category “basemap”. For more information please
take a look at
Basics concerning the category „basemap“.

Sprachenkarte von Kärnten
This map gives a demographical and linguistic overview about the linguistic
circumstances in Carinthia in the years 1919 and 1920. The cartographer Arnold
Hillen Ziegfeld, who developed the so-called suggestive cartography, drew this map.
The draft was produced by Martin Wutte.

It is a military map and uses different signs (arrows, frontlines) to symbolize the
fights of the Kingdom of Yugoslavia and of the Carinthians.
The draft of this map was drawn by Martin Wutte.

Basemap 0
This kind of basemap was used to produce huge scaled maps on tracing paper.
In this process of production, tracing paper was put on the topographical basemap and
different linguistic phenomena were drawn onto it.

Basemap 1
This map is titled “Bayer.-Österreichischer Mundartatlas”
(“Dialect Atlas of Bavaria and Austria”) – and features a legend outside the displayed map
area. The title refers to the different names of Kranzmayer’s dialect atlas during the
years of its production.

Basemap 3
This map was produced during National Socialism, as depicted in the
legend and the territorial borders.
|

|
Basemap 4
This map has „Grundkarte“(basemap) as a title and depicts the political
borders before the „Anschluss“.

displays four crosses in each corner of the map for putting a a map made of tracing
paper on it. The map is set in the First Republic.

Basemap 7
This basemap also has „Grundkarte“ (basemap) in its title and was created in
the year 1970 when a second series of testprints of Kranzmayers dialect atlas was
initiated.
|

Basemap 8
This map has a lot of similarities with basemap 2-3 and was
created during the time of National Socialism.
