aerial困难

Aerial surveys locate general areas of interest or larger buried features, such as ancient buildings or fields.

航空勘测可以确定值得关注的大致区域或较大的地下遗迹，如古代建筑或田地。

Surveys can cover a single large settlement or entire landscapes. In one case, many researchers working around the ancient Maya city of Copán, Honduras, have located hundreds of small rural villages and individual dwellings by using aerial photographs and by making surveys on foot. The resulting settlement maps show how the distribution and density of the rural population around the city changed dramatically between AD 500 and 850, when Copán collapsed.

勘测的范围可以是单个大型聚居地，也可以是整片地域。在一个案例中，许多在洪都拉斯古玛雅城市科潘周边工作的研究人员，借助航拍照片和徒步勘测，找到了数百个小村落和独立住所。由此绘制的聚落地图显示，从公元500年到科潘衰亡的850年间，该城周边农村人口的分布和密度发生了巨大变化。
