[Abstract]:Real scene image is a ground stereo image with absolute azimuth elements in the sequence of time series integrated and integrated management. Visual, measurable and mining images contain spatial semantics that cannot be represented by traditional maps, and represent the physical conditions of the earth. They are holograms with social, economic and humanistic knowledge related to people's living environment. In recent years, the real scene image data with its measurable, can provide urban landscape elevation image and mining natural and human social information and many other advantages, gradually become an important supplement to the field of surveying and mapping 4D products. And in the "digital city" in many applications play a supporting role. With the rapid development of vehicle real scene image acquisition technology and the popularization of urban real scene image application, in the construction process of "digital city" and "intelligent city", Surveying and mapping management departments at all levels and many urban functional management departments (such as urban management) have collected a large number of real scene image data according to their respective needs, and have constructed a real scene image system with different application purposes. In view of the difficulties of sharing real scene image such as diverse data sources, small access range and low data utilization rate caused by heterogeneous systems, this paper analyzes and draws lessons from the OGC network space service specification system in depth. According to the characteristics of real scene image data and its application, from the point of view of improving the sharing mode of real scene image data and enhancing the interactive ability of real scene image application, this paper puts forward the research of network real scene image space service (Web Image Service, WIS), including service description and discovery. Interface and interactive service model. On this basis, the paper studies the implementation method of the service, and verifies the usability and ease of use of the service, combining with the application of "Tian Maps City" and "Digital City Management" and so on. The main contents and achievements of this paper are as follows: 1. This paper analyzes the typical spatial service specifications that represent data service, display service and processing service in OGC spatial service system, and from the angle of whether these specifications can improve the sharing mode of real scene image data, This paper presents a WIS model structure to improve the interactive ability of real scene image application. 2. According to the structure of WIS model, the service model of WIS is studied from four aspects: service description, service discovery, interface design and interaction mode. The description elements, service capability and function sequence of service description are studied. The key words and spatial information matching methods of service discovery are discussed, nine service interfaces that can be realized by real scene image are designed, and the interactive methods of service are analyzed. 3. The prototype of WIS is designed from the hardware layer, data layer, business layer and interface. Taking the real scene image of Haian city as the experimental data, the application examples of WIS prototype are constructed by combining the map resources of "Digital City Management" and "Tian Maps City", respectively. The application pattern of WIS is refined to verify the usability and ease of use of WIS.
