General
The overview of the Sulzberger map has been used to add a road network as-of 1838 to OHM. Other maps are not available in the required detail.
- Sulzberger map 1838: https://commons.wikimedia.org/wiki/File:6526410-maximum_Sulzberger1838.jpg [individual sheets not PD]
- Dufour map [not PD]
- Siegfried map [not PD]
- Orthofoto 1946 first one, then starting 1980s [maybe use 2017 from OSM, others unclear?]
railroads were built in the 1850s and 1860s, so mapping those is interesting.
Detailed
Arbon
Arbon has been mapped with the 1768 map in general outlines and the "Situationsplan" (1884) on a building-level, further buildings since have been added as well.
Frauenfeld
Frauenfeld has been mapped using the detailed sheet of the Sulzberger map 1838 (buildings still missing).
