在地形测绘方面,澳大利亚用机载地形断面制图仪和氩激光器已经测量了188,000平方哩.该仪器由武器研究所发展,并由国家发展部的测绘局使用.具有2米水平分辨率的光束,从大约2000米高的仪器投射到地面上,产生直径30厘米的光点. In topographic mapping, Australia has measured 188,000 square miles using airborne cross-section mapping machines and argon lasers, developed by the Weapons Institute and used by the Bureau of Mapping, Ministry of National Development, with a 2-meter horizontal resolution beam, Projected onto the ground from an instrument of about 2,000 meters in height produces a spot of 30 cm in diameter.
