日治初期台灣總督府完成平地的土地測量事業後，即將土地調查事業重心轉移到蕃地。1908-1916年測繪的「五萬分一蕃地地形圖」為台灣山地首次的詳細地形調查，並紀錄了當時山區道路、部落位置及蕃界等珍貴的空間資訊。由於該套地形圖的製作過程未留下完整的測繪報告，國內各典藏單位也多未進行館際間的圖資比對，使得該套地圖常出現詮釋資料錯誤或版本誤解的情況。本研究首先介紹此套地形圖在國內外各館藏的典藏現況，藉由史料文獻的考察與各館藏圖資的交叉比對，釐清本套地形圖測繪的脈絡。進而揭示在68個正式版圖幅之外，仍有另外三種特殊版本共45圖幅的存在。研究成果將可作為後續數位典藏工作的重要參考，並提供相關研究者進行台灣山地研究的地圖索引依據。

At the early stage of colonial Taiwan, the Governor-General of Taiwan shift the focus of land survey to aboriginal land after finishing the work of plain areas. The "1/50,000 Aboriginal Topographic maps", surveyed from1908 to1916, present the first detailed topographic investigation on mountain areas in Taiwan with valuable spatial records such as mountain roads, settlement positions and the aboriginal boundaries. However, due to the uncompleted mapping and survey reports and the insufficient of the map collection comparison, we may easily find the metadata mistakes or misunderstanding of the map versions in the library. This study first introduces the current archives of these maps among the domestic and overseas map collection units. By comparing all the versions of these maps with an investigation of historical materials, we clarify the producing context of this set of topographic map. Furthermore, the result reveals that beyond the formal published 68 maps, there are another 45 map sheets exist in three additional versions. The efforts of this study not only become an important reference for further digital archive's works, but also provide useful guiding maps for the study of central mountains' areas in Taiwan.
