叙利亚考古遗址的数字高程模型和地形图是通过手持式激光测距仪进行现场地形测量，并使用带有地理信息系统软件的笔记本电脑进行数据后处理来创建的。即使在该国的技术和政治限制下，该方法也能实现快速的现场地形测绘。在约1 km2的区域内，测量地表随机点的坐标，并利用克里格插值法从点云中生成间隔为10 m的网格的DEM。 DEM 可以构建各种地形表示，例如等高线、横截面和坡度分布图。将 DEM 导出的间隔 1 m 的等高线与显示道路和建筑物的矢量数据相结合，以提供地形图。从 DEM 创建的地形横截面通常与使用水平仪和卷尺测量的剖面一致。获得的DEM和地图对于初步的实地研究很有用。
A digital elevation model and a topographic map of an archaeological site in Syria were created from a field topographic survey with a handheld laser range finder and data post-processing using a notebook personal computer with Geographical Information System software. The method enabled rapid on-site topographical mapping even under technical and political restrictions in the country. In an area of about 1 km2, coordinates of random points on the land surface were measured, and a DEM with a 10 m interval grid was generated from the point cloud using Kriging interpolation. The DEM enables various topographic representations to be constructed, such as contour lines, cross sections and slope distribution maps. The DEM-derived contour lines with a 1 m interval were combined with vector data showing roads and buildings to provide a topographic map. Topographic cross sections created from the DEM generally agree with sections surveyed with a hand level and a measurement tape. The obtained DEM and map are useful for preliminary field research.
