GeoWorlds (http://www.isi.edu/geoworlds ) is a component-based information management system aimed at helping organizations to marshal, analyze, discuss, and act on all of the available information about a situation playing out over space and time. The system integrates digital library, geographic information systems (GIS), and remote sensor data management technologies, together with other inf...

Service-oriented architecture supports data and model sharing and interoperability. The concept of such a service-oriented and distributed architecture is applied to build and integrate web-based service models of ecological resources quantitative measurement. The paper is to develop and integrate a GI web service by using an algorithm that calculates net primary productivity of terrestrial veg...

Lack of detailed land use (LU) information and efficient data collection methods have made the modeling of urban systems difficult. This study aims to develop a novel hierarchical rule-based LU extraction framework using geographic vector and remotely sensed (RS) data, in order to extract detailed subzonal LU information, residential LU in this study. The LU extraction system is developed to ex...

The contribution deals with issues that are very closely connected: Web services model, Dynamic GIS and the problem of uncertainty of spatial data and discusses the possibilities of the context use as a reflection of the system of understanding. The problem of the relation to the decision support system is addressed and GIS as a tool dealing with all phases of knowledge structure. GIS Web servi...
