在野外收集地理数据既费时又费钱。为了把这些使人困惑的情况缩小到较小规模,起初可以使用遥感图象。例如遥感方法可以用来识别和监测海岸的和生物物理的过程。在这项研究中,这些技术作为确定植被覆盖海岸沙丘凹地的空间型式的第一步是有价值的。 Collecting geographical data in the field is both time-consuming and costly. In order to reduce these confusing situations to a smaller scale, remote sensing images can initially be used. For example, remote sensing methods can be used to identify and monitor coastal and biophysical processes. In this study, these techniques are valuable as a first step in determining the spatial pattern of vegetation covering the valleys of coastal sand dunes.
