Paper Title	An API for Visualizing Data from the Sensor Web
I can give a practical demo	yes

Paper Abstract (short)

In this presentation a library for facilitating the development of OGC Sensor Observation Service (SOS) clients will be introduced that hides all complex interactions with the SOS interface by providing a simple, lightweight API based on REST and JSON.

Paper Abstract (long)

This presentation will show how observation data from the Sensor Web, i.e. provided through the standardized OGC Sensor Observation Service (SOS) interface, can be accessed and visualized through web-based clients. For this purpose, the open source 52¡North Sensor Web Client API will be introduced. The 52¡North Sensor Web client has been available for several years and provides a very broad range of features for displaying sensor data (i.e. time series data as graphs and tables). This is complemented by additional functionality for creating notification rules and for subscribing to according alerts (based on the OGC Sensor Event Service Discussion Paper). To achieve such functionality, any OGC SOS client needs to be able to gather the necessary metadata from SOS servers. This includes information such as the parameters, the sensors as well as the geographic features for which observations are available. Based on this metadata a client becomes able to display the available data sets and to allow the user a selection of the data he is interested in. The implementation of this metadata retrieval and analysis task is a fundamental step for every SOS client developer that requires good knowledge of the OGC SOS standard as well as a significant amount programming work. However, as this metadata retrieval functionality is a common element of basically all SOS client implementations, the decision was taken to isolate this functionality into a separate software module which can be re-used by any other SOS client. The same applies to the actual observation data retrieval. Also in this case client implementers would need to work with the SOS standard and often very large XML documents. Looking at lightweight clients, for example running on mobile phones, the handling of such large XML documents is usually not feasible. Instead a (server-side) component hiding the complex SOS requests and handling the parsing of XML responses is needed. The result of this work is a REST based client API which hides all complexity of the SOS standard as well as the individual requests necessary for retrieving sensor metadata and time series. Thus, instead of relying on the rather complex SOS interface, client developers can use simple REST requests to gather meta-information about available data in a SOS server and to retrieve the according time series data. In order to avoid the need for complex processing of XML documents, the responses of the client REST API are returned as lightweight JSON documents (or even PNG files containing rendered time series diagrams). Within this presentation, this API will be introduced and interested developers will receive best practice guidance how they can rely on the Sensor Web Client API for building their own SOS client applications. As a result, the creation of Sensor Web clients, especially OGC SOS clients, can be significantly facilitated. Also the enhancement of other, existing client frameworks with functionality for displaying near-real time and archived sensor data becomes a very easy task that can be quickly achieved.

Paper Title	An introduction to Open Source Geospatial
I can give a practical demo	no

Paper Abstract (short)

This is a presentation focused on gently introducing the unitiated to the concepts of Open Source, Free Software licenses and the associated business models.

Paper Abstract (long)

ngs of Open Source development and Free Software licensing. The second part of this presentation introduces OSGeo's mission, goals and the organizational structure implemented to achieve them. To make it a little more bearable all of this is wrapped up nicely and bundled with the story of how Open Source was the natural thing to do, how it was then pirated and appropriated by closed business models and how it eventually has been conquered back once the Internet came into being for real. Now - knowing that we are all geeks none of us really wants to hear this again! And why do we need to preach to the converted? Well, you don't have to. But there are still people out there who ask: * Is it really all gratis - er - free? * Who can I sue when it goes wrong? * How can this be reliable? * Do I get support? Therefore this kind introduction to Free and Open Source Software for Geospatial is still important and often gets neglected in the more geeky conference. But if we want to get anywhere we will have to help folks who still think by themselves: * This Open Source stuff is insecure and unsafe. * Open Source = unlicensed = pirated. Better stay away! * Nobody serious is using this for real. * It's all for geeks only. * I am too old to learn this. * Nobody will behead me if I stuck with the old crap and everything falls apart. And so on. In case there is no other presentation addressing these topics and the need for an introduction is seen then I am prepared to give it (yet again) with a decade of experience and trying to not look to bored by it.

Paper Title	Analysis of Realtime Stream data with Anvil
I can give a practical demo	yes

Paper Abstract (short)

This talk will present Anvil, an open-source realtime stream processing fabric that makes it possible to connect, georeference, analyze, and visualize high-rate data.

Paper Abstract (long)

Realtime geospatial data has become more prevalent and relevant in the areas of disaster response, crisis identification, government operations, and business branding and engagement. In particular, Social Media provides for a new wealth of personalized, qualitative data that gives an unprecendented view of live, on the ground information. Our traditional tools are ill-equiped to access, store and understand these stream of data. Anvil is a new open-source realtime stream processing fabric that provides a stable and flexible service for on-demand data access and analysis. Leveraging the Storm and Hadoop frameworks, Anvil extends these to add a pluggable spatial processing components for capabilities such as sentiment scoring, social network analysis, aggregation, alerting, and even emergent event detection. It includes libraries for realtime visualization of high-volume data in server and client-side analysis. This talk will present the Anvil project, how it works and ways it is being used by government and businesses. We will demonstrate visualization of hundreds of points per second and millions of features in the browser using HTML5 and Javascript.

Paper Title	Assessing risk of dangerous goods transport with GeoServer, GeoBatch and MapStore: an introduction to the Destination project
I can give a practical demo	yes

Paper Abstract (short)

A practical example on how GeoServer, GeoBatch and MapStore can be used to build a complex geospatial application for real-time monitoring, supporting decision making processes, emergency assessment and management

Paper Abstract (long)

The presentation will provide a practical example on how GeoServer, GeoBatch and MapStore can be used to build a complex geospatial application for real-time monitoring, supporting decision making processes, emergency assessment and management DESTINATION (DangErous tranSport To New prevenTive Instruments) is a project developed in the framework of Italy/Switzerland Operational Programme for Trans-frontier Cooperation 2007-2013, in order to contribute to inter-regional road accident prevention, real-time monitoring of Dangerous Goods Transportation (DGT) and more efficient emergency management. Partners include Regione Piemonte as project leader, Canton Ticino, Regione Lombardia, Regione Autonoma della Valle dÕAosta and Provincia Autonoma di Bolzano. Technical partners working on the solution components are CSI-Piemonte, 5T S.r.l., Politecnico di Milano and Fondazione Lombardia per lÕAmbiente. DESTINATION initiative is focused on implementation of a shared information system including environmental, territorial and technical data relevant to meet local authorities and private stakeholders needs: The presentation will analyze how the different needs of the Destination project have been solved using the above mentioned OpenSource projects. We are going to discuss how the data coming from the various partners involved in the project can be automatically ingested and preprocessed using GeoBatch flows and actions, harmonizing and transforming them in the most appropriate format for the application needs Then we will introduce GeoServer WPS process development, to discover how to build processes for on-the-fly risk calculation and simulation, and through rendering transformations viewing the output of the calculation processes directly on a map. We will also learn how to build dynamic thematic maps using GeoServer sql views, using current user input as parameters. eventually we will show how MapStore has been used as the basis to develop a custom webgis interface integrating and orchestrating OGC services.
