From 1875 to 1931, the Prussian state produced a series of large-scale topographic maps known as measuring table sheets. This map work, created by the Bundesamt für Kartographie und Geodäsie, constituted the most detailed topographic basis for the area of the German Empire at the time. The sheets are plano maps, primarily monochrome with some multi-colored prints.
Prussian territory was mapped starting in 1822. These hand-drawn, one-off Prussian Original Survey Sheets were produced at a scale of 1:25,000 to serve as the basis for smaller-scale maps. The Bundesamt für Kartographie und Geodäsie provides this specific sheet for Ketzin from 1867, available as a high-quality plot.
From 1875, the Prussian State Recording began a topographic survey at 1:25,000 scale, which was essentially completed by 1912. This map series, featuring contour lines and a normal-zero reference, was created to meet civilian demand and formed the basis for subsequent map scales. The Bundesamt für Kartographie und Geodäsie provides these measuring table sheets, which are mostly single-colored prints.
Prussian Original Survey Maps were hand-drawn, one-off topographic maps produced starting in 1822 for the entire territory of Prussia. They were created at a scale of 1:25,000 and were not published, serving as the foundational basis for smaller-scale maps. The specific sheet for Blankenfelde was produced in 1869 by the Royal Prussian General Staff.
Measuring table sheets are large-scale topographic maps of the German Empire produced between 1875 and 1931. The Prussian state began the survey in 1875, with the work essentially completed by 1912 and updated photographs finished by 1931. These plano maps, primarily monochrome, were created by the Reichsamt für Landesaufnahme to meet civilian needs and feature contour lines referenced to normal zero.
Prussian territory hand-drawn topographic maps produced beginning in 1822. The maps are one-of-a-kind, created at a scale of 1:25,000 to serve as the basis for smaller-scale maps. They were produced by the Royal Prussian General Staff, with content and design standardized by instructions issued in 1821.
Prussian Urmesstischblätter are original topographic survey maps produced starting in 1822 for the entire territory of Prussia. The maps were hand-drawn one-offs at a scale of 1:25,000 and were not published, serving as the basis for smaller-scale maps. The Bundesamt für Kartographie und Geodäsie provides these sheets, which mark the beginning of modern topographic cartography.
From 1875, the Prussian State Recording began producing topographic maps at a 1:25,000 scale, with the work largely completed by 1912. These measuring table sheets, featuring contour lines and a standard reference level, formed the primary large-scale map series for the German Empire's territory by 1931. The Bundesamt für Kartographie und Geodäsie provides these historical map sheets, which were typically supplied as single-color prints.
From 1875, the Prussian State Recording began producing topographic map sheets at a 1:25,000 scale, a process largely completed by 1912. These maps, featuring contour lines and a standard vertical datum, formed the primary large-scale topographic series for the German Empire's territory by 1931. The Bundesamt für Kartographie und Geodäsie provides these historical map sheets, which are typically single-color prints.
Prussian Urmesstischblatt topographic map sheets were produced starting in 1822 for the entire territory of Prussia. The maps are hand-drawn unique pieces at a scale of 1:25,000, forming the basis for smaller-scale maps. They are available as high-quality plots, with some individual sheets reworked to be more similar to the original color scheme.
Prussian territory is covered by hand-drawn topographic maps produced starting in 1822. The maps are unique pieces at a scale of 1:25,000 and were created by the Royal Prussian General Staff to serve as a basis for smaller-scale maps. They are available as plano prints, with some individual sheets reworked to match the original color scheme.
From 1875, the Prussian State Recording began producing these 1:25,000 scale topographic map sheets, with the work essentially completed by 1912. The Bundesamt für Kartographie und Geodäsie provides these plano sheets, which were the largest-scale topographic map series for the area of the Reich Office for Land Recording by 1931. They feature contour lines, a normal-zero reference, and were primarily intended to satisfy civilian demand.
1822 marks the start of production for these foundational topographic maps covering the entire territory of Prussia. The Prussian Urmesstischblatt are hand-drawn unique pieces at a scale of 1:25,000, created by the Royal Prussian General Staff to serve as a basis for smaller-scale maps. They are available as plano prints, with some individual sheets reworked in color to more closely resemble the original hand-drawn state.
Prussian State Recording produced these 1:25,000 scale topographic maps of the German Empire, beginning in 1875 and essentially completed by 1912. The Bundesamt für Kartographie und Geodäsie provides the maps, which feature contour lines and a normal-zero reference. New photographs of pre-1875 sheets were completed in 1931, forming the largest-scale topographic map work for the area.
A series of biquinoline-based guest molecules were synthesized to achieve red organic room-temperature phosphorescence with an efficiency of 47.53% and a lifetime of 702 milliseconds. The dataset contains crystallographic information files for materials developed by Jiajun Wu, published on figshare in April 2026. The optimized doped material exhibits bright red emission centered at 616 nm.
Hand-drawn Prussian original survey maps from the early 19th century mark the beginning of modern topographic cartography. The production of these one-off maps began in 1822 for the entire territory of Prussia at a scale of 1:25,000. The Bundesamt für Kartographie und Geodäsie provides these sheets, which were intended as a basis for smaller-scale maps and are available as plano prints or high-quality plots.
Beginning in 1822, the Royal Prussian General Staff produced these unique, hand-drawn topographic maps at a scale of 1:25,000. They were created as foundational documents for smaller-scale maps and mark the start of systematic topographic cartography in Prussia. The Bundesamt für Kartographie und Geodäsie provides these sheets, which are available as high-quality prints.
