"The Struve Arc is a chain of survey triangulations stretching from Hammerfest in Norway to the Black Sea, through 10 countries and over 2,820 km. These are points of a survey, carried out between 1816 and 1855 by the astronomer Friedrich Georg Wilhelm Struve, which represented the first accurate measuring of a long segment of a meridian. This helped to establish the exact size and shape of the planet and marked an important step in the development of earth sciences and topographic mapping. It is an extraordinary example of scientific collaboration among scientists from different countries, and of collaboration between monarchs for a scientific cause. The original arc consisted of 258 main triangles with 265 main station points. The listed site includes 34 of the original station points, with different markings, i.e. a drilled hole in rock, iron cross, cairns, or built obelisks."
斯特鲁维地理探测弧线
"斯特鲁维地理探测弧线是一个三角测量链,北起挪威哈 默菲斯特(Hammerfest),南至黑海,弧线穿越十个国家,长2820公里。弧线是天文学家弗里德理西·格奥尔格·威廉·斯特鲁维 (Friedrich Georg Wilhelm Struve)于1816至1855年期间进行测量的测量点,代表着人类首次对子午线长短的精确测量。这一测量帮助人类掌握了地球的确切大小和形状,是地 球科学和地形绘图学发展中的重要一步。这个弧线不仅是多国科学家通力合作的一个特例,也是多国君主为科学事业联袂协作的一个特例。原始弧线包含258个主 要三角形和265个测量站点。列入世界遗产名录的弧有34个原始测量站点,带有各种不同标记,如岩石钻孔、铁十字、堆石标或方尖石碑。"
