The old copies were in bad condition. And there were no original maps to redraw the copies. Sometimes, because land division had not been properly registered, there were cases of "land on the map but not in the books," "land in the books without land on the map," inconsistencies between the actual land area and the map, and so on.
副圖折舊率高，又沒有原圖可以重新描繪，有時則因土地分割沒有做好登記，會造成「有圖無簿（土地登記簿）」，或「有簿無圖」，或是圖與地的面積不一致的情況。
