Thanks to the web 2.0 services and platforms, internet has become a collaborative environment from where massive amount of data enriched with location information is being shared constantly. In this context, we propose a web service called Web 2.0 Broker (W20B) which implements OpenSearch Geo&Time extension offering to the user a common entry point to retrieve an aggregate web 2.0 content according to spatial and temporal criteria

W20B and Eurogeoss Discovery Broker Integration

W20B Component is integrated into EuroGEOSS brokering platform as an accesor into the Discovery Broker. Its fundamental aim is retrieving information from social networks related to forestry, biodiversity and droguht which will be aggregated with the rest of the gathered content to be presented to the user after a search

España Virtual prototype. In the context of "CENIT España Virtual" the developed web client application offers a user-friendly interface to facilitate users' access to the functionality of W20B, in order to provide discovering and integration of web 2.0 content into Geospatial Information Infrastuctures in a simple and visual way.

The Geospatial Framework (GF) is a Web client application that implements the client side of the OpenSearch Geo-Time interface and the Web Processing Service (WPS). The main objetive is to provide a friendly user interface for OpenSearch Discovery services, in particular the Web 2.0 Broker (see above) and Processing Services. For a demonstration on its functionality you can see this video[Video]. Current research extends preliminary work, (see the The Service Framework) to have a unique entry point (with a friendly interface) to a Geospatial Infrastrucure (GI), so users can not only search and access but also process and publish new geospatial resources.

GEOSS Service Factory. Geospatial applications have changed from isolated solutions to open infrastructures based on Web Services to deal with data representing the status of our environment. International organizations and initiatives promote standards for data encodings and service interfaces that allow establishing Geospatial Information Infrastructures (GIIs). These GIIs provide services to address most of the steps in the geospatial user workflow, such as discovery, access, visualization and invocation. However, they do not provide services to assist users in the publication of content. The lack of this functionality challenges the implementation and maintenance of GIIs since publication of content remains a complex task turning GIIs into top-down infrastructures without user participation. GEOSS Service Factory (GSF) is a publication service that aims at extending classical GII architectures to provide this publication capacity.

Access to GIS data from mobile platforms continues being a challenge and there exist a wide range of fields where it is extremely useful. In this work, we combined three key aspects: climate data sensors, mobile platforms and spatial proximity operations. We publish and made use of a web 2.0 network of climate data, where content is user-collected and exposed as available information for the virtual community. Management of this type of information from a mobile application could result in an important decision tool as it enables us to provide user with climate-related data according to his context and geographical location. Therefore, we implement a multiplatform mobile web application with jquerymobile, ArcGIS API for javascript and integrated with ArcGIS webmaps that allows us to perform geospatial queries based on user location offering, at the same time, access to all data provided by the climate data sensor network.

Poligon survey and publication on a SDI using Adroid device. The application show the layer using a Web Map Service. It also extracts the burned area of the base layers (Corine Land cover and Natura 2000 protected Areas) using a Web Feature Service by implementing a clip from a Web processing service.
