Topographic map sheets of the German Empire at a 1:25,000 scale, produced by the Prussian State Recording and later the Reich Office for Land Recording. The mapping effort began in 1875 and was essentially completed by 1912, with new photographs of older sheets finished by 1931. The sheets feature contour lines and a normal-zero reference, forming the largest-scale topographic map series for the area at the time.
Use Cases
- Historical land-use analysis based on topographic features like contour lines.
- Study of cartographic techniques and standardization based on the normal-zero reference system.
- Georeferencing and comparison with modern maps based on the precise 1:25,000 scale.
Strengths
- Mapping effort spans over five decades, from 1875 to 1931.
- Sheets formed the largest-scale topographic map series for the area of the Reich Office for Land Recording.
- Description specifies the use of contour lines and a normal-zero reference for elevation.
Limitations
- Last updated 1932-01-01 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic and temporal bias inherent to the historical mapping project.
