Even that was incomplete, however, as it only covered plains land, accounting for only about 54 % of Taiwan's total surface area. State-owned land like mountains and wilderness "slipped through the net," pending later field surveys.
不過即使如此，當時測量的仍以一般平原私有地為主，佔台灣總面積的百分之五十四；如山坡地、原野地等公有地都是「漏網之魚」，有待後來進行林野調查。
