结合柬埔寨项目1∶2000地形图测绘项目，介绍机载激光雷达技术在植被茂盛的密林地区测绘中的应用，重点介绍了项目实施中技术方案的制定和数据后处理的过程。试验表明，机载激光雷达技术可以解决大面积森林覆盖地区、沙漠、沼泽、草原等困难地区及其他无法到达或危险区域的测绘工作，能够大量减少人工成本并获取丰富的地形测量成果，成果精度满足相关规范要求。
結閤柬埔寨項目1∶2000地形圖測繪項目，介紹機載激光雷達技術在植被茂盛的密林地區測繪中的應用，重點介紹瞭項目實施中技術方案的製定和數據後處理的過程。試驗錶明，機載激光雷達技術可以解決大麵積森林覆蓋地區、沙漠、沼澤、草原等睏難地區及其他無法到達或危險區域的測繪工作，能夠大量減少人工成本併穫取豐富的地形測量成果，成果精度滿足相關規範要求。
결합간포채항목1∶2000지형도측회항목，개소궤재격광뢰체기술재식피무성적밀임지구측회중적응용，중점개소료항목실시중기술방안적제정화수거후처리적과정。시험표명，궤재격광뢰체기술가이해결대면적삼림복개지구、사막、소택、초원등곤난지구급기타무법도체혹위험구역적측회공작，능구대량감소인공성본병획취봉부적지형측량성과，성과정도만족상관규범요구。
With practice of the surveying of 1∶2000 topographic map in Cambodia project, application of the aircraft-carrying laser radar technology in surveying in the region where vegetation is flourishing and dense.Preparation of the technical proposal and course of the post data processing in the project implementation are introduced especially .The tests prove that the aircraft-carrying laser radar technol-ogy can realize the surveying and mappingof the regions where forests cover in a large area, deserts, marshland and grass land, etc and it is difficult to reach and perform the surveying or the area where is dangerous, and it is impossible to survey.The technology can largely reduce manpower cost and obtain abundant topographic surveying results.The surveying precision satisfies the requirements of relevant specifications .
