Yokohama City Topographic Map

　The "Thousands One Topographic Map" was created as a basic document for city planning in response to the enactment of the Old City Planning Act of 1919 (Daisho 8).
　Yokohama City has begun surveying detailed topographic map surveys since 1921 (Daisho 10) with the aim of creating a "Thousands of One Topographic Map". This initiative was forced to be interrupted due to the Great Kanto Earthquake (1923 (Daisho 12)), but we started surveying again in 1925 (Daisho 14).
　In this effort, we refer to the basic data of urban planning in Europe and the United States. Kuo with a scale of 1 / 3,000, 2,400 meters east-west, 1,800 meters north-south, and 1,800 meters north-south, was planned to cover Yokohama city area at that time with 53 leaves.
　Looking at the remaining topographic maps, it is confirmed that before the war, 3,000-minute topographic maps were created based on detailed topographic map surveys until 1938 (Showa 13), but after that it became a severe wartime system. It can be seen that the creation of a 3,000-by-one topographic map created by the Land Survey Department (current Geographical Survey Institute) is enlarged and used. You. 。 From 1949 (Showa 24) to 1950 (Showa 25), a topographic map was created near Kanazawa, where maps could not be created before the war.
　After that, mainly in the 1930s (1954 (Showa 29) to 1965 (Showa 40)), a topographic map of 3,000 bun was newly created. The 3,000-minute topographic map of the 1930s was created by aerial photography survey, and the scale is the same 1 / 3,000 meters east-west and 2,000 meters north-south, and 90 meters north-south.
