面向对象的城市空间信息遥感分析的理论框架

提出了面向对象的城市空间信息遥感分析的理论框架.对图像对象、地理空间对象和城市空间对象做出了明确界定,详细说明了三者间的区别和联系;总结了地理空间对象识别的三准则:边界、属性和尺度;提出地理空间对象和城市空间对象由身份、状态和行为三部分构成,对应的形式表达为标识、属性和关系.在分析地理空间对象中所包含信息的三个维度——专题、空间和时间的基础上,详细说明了组成地理空间对象和城市空间对象的专题属性、空间属性、时间属性和专题关系、空间关系、时间关系.在理论基础上,建立了一个通用的面向对象的城市空间信息遥感分析的总体框架.

Exploring the theoretical framework of object-oriented analysis for urban spatial information using remote sensing data

In this study, three basic concepts: image object, geospatial object, and urban spatial object were examined, and the dissimilarities and relations among them were elaborated. Three criteria boundary, attributes, and scale-were proposed to characterize different types of geospatial objects. This research reveals that each geospatial or urban spatial object is defined by three components: identity, state and behavior. These three components are represented by unique name (or identification number), attributes, and relationships respectively. In addition, the information associated with an object has three dimensions: theme, space and time. The thematic, spatial, temporal attributes and relationships are the information underpinnings of a geospatial and urban spatial object. As a significant result of this paper, a general framework for object-oriented analysis of urban spatial information is established. The author believes that this framework may have wide applications in the field.
