摘要
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、同步的信息。本体是对概念化的明确描述和说明,更接近于认知模型,易于理解和共享;同时又能以计算机可操作的形式化语言明确表达目标领域的概念体系及其蕴含的语义。因此,在分析和借鉴现有相关研究的基础上,将本体、语义思想引入到遥感影像表达,建立了基于本体的城市遥感影像解译应用语义模型和解译框架,应用此框架将有助于提高城市遥感影像解译的精度与效率,对推动遥感技术在城市相关领域中的应用有着积极的意义。
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. Ontology is a definite description of conceptualization. It can be showed closer to cognitive model and easier to he understood and shared; it can be also operated by the computer＇s formal language to express a tangible goal in the field of the concept and its implication semantics. As a result,with the existed researches analyzed and learned, the thought of Ontology and Semantic are introduced to the expression of the RS images. Moreover, semantic model and interpretation framework of RS images for urban field based on Ontology are built up in this paper. Then the semantic model in the processing procedure of urban RS images was formed to improve the accuracy and efficiency of RS technology in urban field.
