城市遥感影像语义模型

Remote sensing semantic model for city planning

在快速的城市化进程中,遥感技术可以为城市土地利用变化提供直观、准确、同步的资料。在应用城市遥感影像的过程中,根据城市的社会、经济及自然环境特征,按照城市用地类型的分类建立不同功能区的模型,最终结合起来,组成整个城市的遥感影像判读应用语义模型,使在目视判读中所积累的知识应用到计算机的自动判读过程中,以提高遥感技术在城市领域的应用精度与效率。

With the accelerating process of urbanization, the technology of Remote Sensing （RS） can supply the direct, accurate and synchronous information for the change detection of urban land use. According to the social, economic and environmental characteristics of the city, the different models for various functional districts were built up in term of urban land use classification, then the semantic model in the processing procedure of urban RS image was formed to improve the accuracy and efficiency of RS technology in city planning.
