城市大比例尺地形圖數(shù)據(jù)更新方法及其應(yīng)用
發(fā)布時間:2019-05-13 17:33
【摘要】:以筆者所在單位近幾年研制采用的城市大比例尺地形圖數(shù)據(jù)更新方法為例,分析討論了分別采用機載Li DAR技術(shù)、地面Li DAR技術(shù)、地圖綜合縮編軟件、建設(shè)工程竣工測量成果、傳統(tǒng)地形圖更新修補測方法進行城市大比例尺地形圖數(shù)據(jù)更新的工作流程、技術(shù)方法,對各自優(yōu)缺點進行了比較,建議5種地形圖更新方法相互借鑒補充配合使用。
[Abstract]:Taking the data updating method of urban large scale topographic map developed and adopted by the author's unit in recent years as an example, this paper analyzes and discusses the survey results of construction project completed by using airborne Li DAR technology, ground Li DAR technology, map comprehensive reduction software, respectively. The work flow and technical method of urban large scale topographic map data updating are carried out by traditional topographic map updating and mending methods, and their advantages and disadvantages are compared. It is suggested that five topographic map updating methods should be used for reference and supplement each other.
