摘要
数据高程的模型技术是4D产品中应用较为广泛的一种,由于此技术自身的有效性,在实际操作中表现出的优越性,以及现实的需求等众多原因,该技术在地形测绘和地理信息的收集等方面应用广泛。ARCGIS和DLG作为DEM高效生产的支持技术,其应用的方式不同,具体的优缺点也不同,论文将对此进行分析和探讨。
The model technology of data elevation is one of the most widely used 4D products. Due to the effectiveness of this technology itself, its superiority in actual operation and the actual demand, it is widely used in topographic mapping and geographic information collection etc..ARCGIS and DLG as the support technology of DEM efficient production, its application method is different, and the specific advantages and disadvantages are also different. This article will analyze and discuss on this.
