Development

How do developers and users of geospatial services know that a service is compliant with a standard? The Open Geospatial Consortium (OGC) provides a Web-based test facility called the TEAM Engine that allows developers to test Web services and clients for correct implementation of OGC standards. The TEAM Engine is a JAVA open source facility available at Sourceforge. The TEAM Engine can be run via command line, deployed in a web servlet container or integrated in a developer’s environment via MAVEN. The TEAM Engine uses the Compliance Test Language (CTL) to test HTTP requests, SOAP services and XML instances against schemas and Schematron based assertions of any type of web service, not only OGC services. For example, the OGC Web Feature Service (WFS) 1.0 test has 468 test assertions, including testing for the following: conformance of HTTP responses with different combinations of HTTP requests; conformance of GML-encoded data; proper values for elements and attributes in the XML; and correct error responses. This talk will provide an overview of the TEAM Engine, show examples of tests made available by OGC, including the test suite for clients that implement the OGC Web Map Service (WMS) Standard, and provide information about how to participate in the open source code development of the TEAM Engine.

During glob3 (https://sourceforge.net/p/glob3/) implementation in the "Virtual plattform for the dissemination of the Science of the Extremadura Goverment" (http://forjamari.linex.org/projects/pdcv), IGO Software developed a dMVC (distributed model view controller) using Java, that allows the usage of remote and local methods, enabling the real-time interaction of all the clients connected to the server. This functionality was already presented in the V free GIS journeys, during a demo that was implemented in Smalltalk in 2008 (http://www.sigte.udg.edu/jornadassiglibre2008/uploads/file/Comunicacione...).

Using a 3D globe, we intend to prove the use of the interacting cappability in a synchronous way in real-time of several users in a SIG functionality such as the vector data editing. It also includes a chat, where edition operators can coordinate them selves. Each actions made in clients will appear instantly in remotes clients. This kind of functionality fits perfectky in collaborative works, for example, the mapping work done after the Haiti earthqueake, that hit it's main city last year. It made possible that a significant number of people could be mapping while viewing in realtime the changes that other users were adding at the same time. Even the rescue team could be mapping directly from the tragedy field, such information was available in real-time.
