Soviet Classified Map

The Soviet General Staff (Genshtab) mapped the entire planet between 1950 and 1990 to a single rigorous standard: khaki-gray sheets, forest-green forest polygons, brown contour lines and a kilometer grid annotated in Cyrillic. Every sheet carried the red СЕКРЕТНО stamp.

This system borrows that disciplined, slightly austere cartography. It is built for density and legibility — flat tinted fills, fine line-work, condensed labels and a precise grid that never decorates, only locates.

1950 至 1990 年间，苏军总参谋部军事测绘局（VTU GSh）以一套统一标准把整个地球 逐幅测绘成图：卡其灰的图纸、森林绿的林地多色块、棕色等高线，以及标注西里尔字母的 公里网格。每一幅图角都盖着鲜红的「СЕКРЕТНО」（绝密）印章。它不浪漫、不张扬， 追求的是覆盖与精确。

这套设计沿用那种克制而严谨的制图语言：扁平的色调填充、纤细的线条、紧缩的标签字体， 以及一张只用来定位、绝不用来装饰的公里网格。配色压抑而冷静，红印章是唯一的强调色。
