摘    要:遥感数据是遥感技术获取的基础数据.从遥感数据中提取地理信息是实现实时空间数据更新的主要手段,但遥感数据与地理信息之间存在着一定的差异.论文分析了遥感数据的相对性,说明遥感反演模型的局限性;分析了遥感数据的确定性与不确定性,说明遥感统计模式识别的局限性.明确遥感数据与地理信息之间的关系,并结合计算机视觉技术和遥感图像处理技术,提出基于遥感数据的地理定性、定量信息提取的概念模型.

关 键 词:遥感数据 地理信息 图像处理

Abstract:Remote sensing data are basic data acquired by the technology of remote sensing. Extracting thematic information from remote sensing data is the main method for updating the digital data in time. Data are the carrier of information, but not equal to information itself. This paper explains the unilateralism of the remote sensing anti-deduce model by the relativity of data, and shows the unilateralism of the remote sensing statistical model by analyzing the authenticity and the inauthenticity of remote sensing data. Further more, this paper defines the relation between remote sensing data and geographic information clearly, and combine the technique of computer vision and the technique of image processing, suggests concept model for extracting the information from remote sensing data.
Keywords:remote sensing data   geographical information   image processing
