GeOnAS is an extensible, scalable and powerful online geospatial analysis system based on Service Oriented Architecture (SOA), and is designed and implemented with the complementary technologies, Asynchronous JavaScript and XML (Ajax) and Web services, which greatly increase the interactive capabilities of graphical user interfaces and improve the user experience. It provides a highly interoperable...
Recent advances in geospatial Web services and Service-Oriented Architecture (SOA) are shifting geospatial data and analysis from the everything-locally-owned-and-operated paradigm to the everything-shared-over-the-Web paradigm. By embracing geospatial content and capabilities within the context of SOA, we have developed a Geospatial Online Analysis System (GeOnAS), a fully extensible system designed...
This paper discusses the implementation of the terrain openness parameter as a Web Service. Terrain Openness is a new morphology parameter that emphasizes surface concavities and convexities (Yokoyama et al., 2002) and can be derived directly from a digital elevation model (DEM). It is essentially an angular measure of the relation between surface relief and horizontal distance and can be used as...
Service Oriented Architecture (SOA), Web Services, Asynchronous JavaScript and XML (AJAX), and other new Web technologies have revolutionized the use of geospatial Web applications. The GeoBrain project has built a powerful online extensible and scalable geospatial analysis system based on SOA. This system utilizes Web Services and AJAX to increase the interactive capabilities of user interfaces and...
