The 1:25,000 topographical maps of Taiwan during Japanese rule period were the official maps made in the late period of Japanese regime (since 1920s and lasted until the end of the World War II), which were precious cartographic heritage because it recorded accurately geoinformation of Taiwan at that time. However, the surveying and mapping for this set of maps have had lasted more than 20 years, and there exist complicated versions of that.
According to the author's observation, there exist at least 5 major categories such as (1) the original survey edition, (2) the revised survey edition, (3) the various versions derived from the restricted zone of fortified area adjustments, (4) secret maps copied by the General Staff of Japanese Empire, (5) the scarlet letter overprinted for the emergently mapped edition by the Taiwan Army Command by the end of the World War II, and so on. The researchers in the past seldom did care about the version differences of this set of maps, which may be caused by the difficulties of obtaining entire maps like the same sheet with various editions at that time. However, there are much differences of the contents between different versions. Take Kaohsiung city for example, from the original 1928 edition to the revised edition of 1942, which is the period that the city has had grown so fast, no matter of the street pattern, the central railway station location, port reclamation area and military base distribution, all of these have had a major change dramatically. If we ignore the version differences, we may get wrong research results and different researchers will be hard to dialogue with each other.
Relying on the developed digital collections of topographic maps nowadays, the author has been obtained thousands of sheets of 1:25,000 topographical maps of Taiwan. This study will start from a large number of map data, make a systemic classification of the versions, and sum up the content differences between different versions, then discuss the cause of the version differences, and analyze the historical value of all kinds of multiple versions on the research of Taiwan geographical changes. Finally, put forward some improvement suggestions to benefit the geoinformation curatorship.
