摘要
随着3S技术的发展,以及林业信息化的需求,RS及GIS在林业中的应用领域也越来越广。本文着重讲述利用SPOT5卫星遥感数据对某乡镇森林资源进行二类调查,结合影像的特征和森林资源调查的具体情况,提出了基于SPOT5遥感数据,利用RS与GIS在森林资源二次调查中的技术流程及方法,包括遥感数据的正射校正、融合处理、波段组合等方面,以及影像的判读解译等。最终得出该乡森林资源的种类、数量、质量与分布情况。
With the development of the 3S technique and the requirement of the forestry information and digitalization,RS and GIS have made widely used in forestry.In this paper,it introduced the forest resource inventory in one village by the SPOT5 remote sensing image data.According to the characteristics of image data and the requirements of forest inventory,the paper discussed the processing procedures and method about the SPOT5 image data with RS and GIS,it included ortho-rectification,image data fusion,image bands composition and Interpretation.At last,it got the result of the kinds,quantity,quality,distributing and so on of forest.
