The Physical Landscape of Britain and Northern Ireland: Technical Development Piccinini, Claudio Geomorphology is the science that analyses how climatic, tectonic and biogenic processes act on the surface of the Earth to create landforms and landscapes. Whilst many organizations recognize the importance of geomorphic processes and landforms in their work, there is no single centralised resource on the geomorphology of Britain. Some useful sources exist but these tend to be thematic (e.g. the BRITICE project), spatially restricted (e.g. GeoEast) or broad-brush (e.g. National Character Areas). The aim of this project is for the first time to provide the interested professional, researcher and the general public with access to information, data and knowledge on the geomorphology of the British landscape. Information will be accessible through an interactive web mapping application built using both open data and open source technologies. The web application will link to bibliographic details of academic studies and reports enabling deeper investigations into a landscape/feature/process. It will be useful to the interpretation of landscape and essential to get the necessary knowledge for assessing environmental impacts, environmental change, environmental hazards and associated risks, and for a wider understanding of the physical environment.

ICOS-Spain Fonts, Oscar; Garcia Coya, Miguel; González Cortés, Fernando ICOS (Integrated Carbon Observation System) is an European Infrastructure whose aim is to provide long-term measurements on greenhouse effect gas emissions. Such measurements will contribute to the analysis and modeling of carbon cycle at continental and global scales. Spain's contribution to ICOS infrastructure counts with the participation of Spanish Meteorological Agency (AEMET), Spanish National Research Council (CSIC) and Mediterranean Center for Environmental Studies (CEAM), among others, and contributes with observations on the atmospheric, terrestrial and maritime domains. In this context, geomati.co has developed an integrated data portal where all the observations from Spanish participation in ICOS will be published on-line. The portal is a fully open source solution, which integrates well known open source components. All of its code and documentation have been released using free licenses.

2011: the first Open census and beyond? Martin, David The first results of the 2011 census in England and Wales were released on 16 July 2012, with the standard outputs for the first time being released under an Open Government Licence. More detailed data, including spatial products such as boundaries for output areas, postcode lookup tables and an entirely new geography of workplace zones will be released in phases through the winter and during 2013, along with API access to area-based statistics. The census spatial datasets provide a widely-used infrastructure for the presentation and analysis of population data, including much non-census information. Even as the results continue to be published, there is a strong possibility that 2011 will be the last conventional census, with a variety of alternative collection strategies and linked data sources currently under review by the Office for National Statistics under the banner of “Beyond 2011”. This presentation will consider the 2011 spatial products, review the potential for entirely new uses of Open census datasets and outline some of the research and licensing challenges that lie ahead.

Analysing GeoServer compatibility with INSPIRE requirements Andrea Aime GeoServer is a well established multiplatform, open source server providing a variety of OGC services, including WMS (view services), WFS and WCS (download and edit services) as well as WPS (spatial data processing services). Among the open source GIS web servers GeoServer is well known for the ease of setup, the web console helping the administrator to configure data and services, the variety of OGC services available out of the box, as well as the rich set of data sources that it can connect to (open source, such as PostGIS as well as proprietary, such as ArcSDE, Oracle or ECW rasters). This presentation provides a history of GeoServer compliance with INSPIRE service requirements, document the current status and provide guidance on how to setup a INSPIRE compliant view service, as well as pointing out deficiencies and providing an overlook on future developments related to this topic.

Urban metabolic mapping on the web: An example from Bangalore, India Mehta, Vishal; Kemp-Benedict, Eric; Wang, Guozhong; Malghan, Deepak Cities are like living entities, needing a continuous throughput of resources and energy for survival and growth, creating waste in the process. This paper documents the Bangalore Urban Mapping Project: an initiative to use this metabolic concept to inform comprehensive planning in the rapidly growing software capital of Bangalore city in India. Focusing on demographic growth, and water supply and consumption in its first phase, a web-based geo-portal has been developed for information delivery. The application, titled Bangalore Urban Mapping Project (BUMP) is built on a free and open source web GIS stack consisting of a Postgis database, PHP, OpenLayers, and Apache Web Server deployed on a 64-bit Ubuntu Linux server platform. The application logic is written in PHP to connect the many components of the interactive application. The application is made available on the BUMP website (http://www.seimapping.org/bump/). The application relies on AJAX to fetch layer data from the server and render the layer using OpenLayers on the fly. This allows users to view multiple layers at the same time without refreshing the page. Data is packed in GeoJSON format and is compressed to reduce traffic. Beyond thematic representation of each of twenty different map layers, graphical and tabular summaries of demographic and water data are presented dynamically using Javascript libraries including the Google Chart API. The application also uses other common Javascript libraries/plug-ins, like jQuery, jQuery UI, qTip, to ease the development and to ensure cross-browser compatibility.

On Interoperability and Web Processing Service setting for Geo- Workflow Quality Assessment and Execution Leibovici, Didier G.; Pourabdollah, Amir; Jackson, Mike When assessing the quality of a workflow and, in particular, its uncertainty propagation, the management of the quality description of the components instantiated within the workflow is essential. This is the case whether one is using clients for quality visualisation or computational services for the error propagation and eventually for the execution of the workflow. This paper describes the benefits and pitfalls - in term of interoperability for data and services - when using a Web Processing Service (WPS) consuming the workflow description to derive the quality and uncertainty propagation and particularly using the meta-propagation paradigm,. The preferred solution, a metadata-profile driven web service implementation, is detailed. This solution, towards a standard interface for workflow services, has the advantage of being easily compliant with any workflow description language standard such as XPDL, BPEL or BPMN2.0. A change of workflow language only implies a server side adaptation for the XML parser method enabling capture of the workflow structure. This metadata-profile driven solution is illustrated by the meta-propagation of uncertainty implemented within the WPS. This interface can be used for generic access, at workflow or sub-workflow level, enabling any other processing upon the workflow elements and therefore allowing general management including its own execution and also data uncertainty sampling, sensitivity analysis, error propagation, visualisations, etc.
