Comments : These maps show the distribution of industrial factories in the International Settlement in 1936, 1938, 1939, and 1940. These maps are based on the industrial surveys by the Shanghai Municipal Police. The 1937 survey is currently missing. These maps belong to a series that documents the changing geography of industry in Shanghai between 1936 and 1940. It is also related to a more general study of industries in the International Settlement from 1930 onward. To analyze the data and synthesize information, we used a vector grid consisting of cells of 250 meters by 250 meters. These units of measurement are more accurate than the police districts, which due to their uneven area mask industrial concentrations. Similarly, the synthesis of data based on block is not too relevant because of the disparities street grid. The grid is very dense in the central districts, producing smaller blocks, and looser in the peripheral districts of the International Settlement. The vector grid is an intermediate scale of representation between block-level and district-level.
