Summary, in English
The majority of spatial data users are inexperienced in spatial information science. This group of users cannot analyze spatial data and produce the required information. Therefore, the availability of mechanisms and applications for automatic and interoperable spatial data processing and information extraction is necessary. Generalization is one of the main geoprocesses, which is widely used. The current generalization algorithms using in web-based processes are controlled by users. Due to the importance of road network maps, in this study we propose a new scale-driven algorithm, which extracts pattern information of road networks and by considering geometrical, topological, semantic, statistical and structural characteristics of road networks, controls generalization process automatically. The algorithm's operation is similar to a set of model and cartographic generalization operators. A prototype service-oriented application is developed as well. The application consists of three types of services. This classification of services improves flexibility and semantic interoperability of the application. In addition, OGC standards (WPS and WFS ) are utilized to establish syntactic interoperability. We have used two methods of service chaining to coordinate services. The paper explains how various chains of the services satisfy requirements of various users using a case study.
