Maps of the German Empire 1: 25 000, measuring table sheets 4049 Lübben

From the year 1875, the founding year of the Prussian state reception, the recording began in the style of the measuring table sheets 1: 25,000 and was essentially completed by 1912. The new photographs of the leaves, which were made before 1875, were completed in 1931. With heightline representation and reference to normal zero, they led to an independent map work, which was primarily intended to meet the increasing civil need. In 1931, the sheets of this work constituted almost exclusively the largest-scale topographic map work and thus the basis for the successive dimensions for the area of responsibility of the then Reichamt für Landesaufnahme. The measuring table sheets are available plano and are mostly supplied as monochrome, rarer than multi-coloured printing.本测绘项目始于1875年——即普鲁士国家测绘事务机构（Prussian state reception）的成立年份，采用1:25000比例尺测图板图幅（measuring table sheets）制式，至1912年基本完成。 1875年前制作的新版图幅影像资料，最终于1931年全部整备完毕。 该系列图件采用等高线表示法（heightline representation）并依托高程基准零点（normal zero）构建，形成了独立的专题地图成果，其核心目的是满足日益增长的民用测绘需求。 1931年，该成果的全部图幅几乎构成了当时规模最大的地形测绘成果体系，并由此成为彼时帝国国家测绘局（Reichamt für Landesaufnahme）管辖区域内后续比例尺地图编制的基础依据。 该测图板图幅以平面图纸形式发行，绝大多数采用单色印刷制式，多色印刷版本较为罕见。
