Paper Abstract (short)
|
An open source solution to flight planning for pilots.
|
Paper Abstract (long)
|
World Flight Planner is a website that allows commercial and private pilots to plan flights. This presentation will describe how we used FOSS4G software to process: - Complex weather data (winds aloft, temperatures) (postgis/postgres) - Parse and plot aeronautical information and real time pilot reports on a map. (geoserver, openlayers) - Show non-pilots the steps involved in pre-flight planning. Aeronautical data can be quite complex and traditional tools offered to pilots are purely text based. Tools like Geoserver and OpenLayers allow World Flight Planner to display this information in a visual format for safer flight planning. Elements from a previous presentation (http://tinyurl.com/badzvae) will be used.

Challenges and successes in implementing real-time, browser-based social media analysis & visualisation with open-source tools.
|
Paper Abstract (long)
|
Twitter has developed over the past few years into a potent source of public opinion and comment. The service passed 500 million users in June 2012, collectively posting hundreds of millions of tweets each day, and several high-profile analyses of this data (such as the Twitter Political Index, which mapped sentiment across the US towards the 2012 presidential candidates over the course of their campaigns) have demonstrated its potential for insight and near-time customer feedback. Handling such large volumes and throughputs of data is a sizeable engineering challenge, however, and several commercial ventures (TweetReach, Tweet Archivist - many others) have sprung up specifically to deal with this complexity - at a cost. In addition, many existing solutions are unable to properly utilise the location data that is present in a significant proportion of tweets, losing out on the rich geographical context. This retrospective aims to demonstrate how an informed coupling of emerging open-source component technologies can be used to resolve the complex problems of i. large stored data volumes, ii. real-time streaming input, iii. concurrency of writes and iv. geographically querying and visualising results - with a minimal development outlay. Specifically, the construction of an open-source process to read, process, write, query and visualise streaming, geolocated Twitter data using the MongoDB NoSQL database and D3.js JavaScript library will be detailed, focusing on how MongoDB handles real-time spatial data (including spatial indexes & querying) and the unique features that make D3 so well-suited to visualising and exploring spatial data in the web browser.

Using OSGeo Live in MSc teaching
|
I can give a practical demo
|
yes
|
Paper Abstract (short)
|
OSGeo Live provides a valuable "system in a box" for MSc teaching in GIS, particularly for creating & managing GIS web services
|
Paper Abstract (long)
|
This presentation will reflect on my experience of using the OSGeo Live system (versions 5.0 and 6.0) for delivering practical class teaching of GIS at Masters level. We have tried various configurations of the system including virtual machines and running from USB sticks and I will discuss the trials and tribulations of setting up the system to run smoothly on the university's network, allowing the students to transport their work between home and the university and explore setting up data in a spatial database, connecting Geoserver to create web services and then connecting QGIS or OpenLayers to the services to access the services. Alongside discussion of the technical details I will reflect on the wide set of technical skills and system understanding needed to truly understand spatial data management, web service creation and management, and creating a good web mapping site. This poses big challenges for teaching the technology in real depth in the limited time in an MSc curriculum.

Using Spatial Business Intelligence for Asset Management
|
I can give a practical demo
|
yes
|
Paper Abstract (short)
|
In this presentation I demonstrate the use of Spatial OLAP for better Asset Management of Provincial Waterways.
|
Paper Abstract (long)
|
The maintenance of waterways is expensive. Optimization of reconstruction projects can save money and limit hindrance for the public. In this presentation I show how the implementation of Spatial OLAP can give better insight in the quality of the construction of waterway banks. By spatially overlaying inspection results with construction records, a better estimation can be made about the overall quality, potential danger and repair costs. Spatial OLAP is an excellent way to provide insight into the different variables involved in the planning proces of maintenance.

Vaadin - A simple approach to GIS-RIApplications
|
I can give a practical demo
|
yes
|
Paper Abstract (short)
|
Vaadin as a RIA framework is very known, unfortunatly not very represented in the GIS scene. With this presentation I hope to increase its popularity...
|
Paper Abstract (long)
|
Vaadin as a framework is very common among Java RIA developers but for GIS developers Vaadin is still a much unknown platform. With this presentation I would like to alter that - and show how a small company developed a stylish GIS RIA application without the needs to switch from the 'classic' language Java. Most web based GIS applications today are written in a mix of languages such as PHP/JS or Phyton/JS, etc. Many frameworks exist to support the development team and make the programming cycle as short as possible. However there is still a downside of choosing a client and a server side technology on its own. The problem starts with knowing at least two technologies to the fullest and there is no end in sight. Even server / client side communication can bring up a few issues and make the developers life really troublesome. With Vaadin these problems are gone, somehow to a certain point. Development starts straight in Java and as it is one of the bigger Java frameworks in the game, support is quite strong and guaranteed. With only on language to develop, the main asset of development is posed on 'making a nice application' rather than 'bolting things together and make it work'. Vaadin somehow enables the focus on the important things instead the technology. The software itself runs on an Apache Tomcat Server and uses Googles GWT framework to render all displaying webpages. Using Vaadin to write a modern GIS application there is still a missing piece in the puzzle. A library, plugin or similar is needed to display all these dynamic maps and enable features to draw and display spacial shapes (polygons, points, etc.). VOpenLayers (vol) is a wrapper class for OpenLayers 2.x developed for Vaadin, it enables the developer to use many of OpenLayersÕs feature in Vaadin. With these 2 components it was possible for us to write a full GIS application in a very limited amount of time and with only limited manpower. Java as a technology was already known, and we had already applications running on the internet with Vaadin technology implemented. So the best step we could make was, try out Vaadin and vol to write our application Ð and it was a great success! In my opinion, customers will seek for rich internet or intranet applications in near future. With Vaadin as an enabling technology it will be very easy to handle the job. The current situation is unfortunately that Vaadin and vol are not very common in our sector. Therefor vol really needs help through developers with deep OpenLayers knowledge to make the next necessary steps for a bug free and feature enhanced version.

WindAR demos 4D gridded wind information, both actual and forecast, overlaid on a live video view on a mobile Android table.
|
Paper Abstract (long)
|
WindAR is a proof-of-concept project that combines Augmented Reality, Open Mapping, Cloud technology, standard weather feeds and mobile hardware to demonstrate visualisation of local weather information. Wherever possible, accepted interoperability standards and packages have been used. Currently, the system displays 4D gridded wind information, both actual and forecast, overlaid on a live video view on a mobile Android tablet, and the demo service has been running for a few months. Areas for simple extensions to the service and further development will be outlined. The current implementation uses OGC WFS and GML v2.0, Google's tile mapping API, WMO (World Meteorological Organisation) GRIB (binary gridded) data format, open source Iris and Cartopy python libraries, Augmented Technologies AWILA package, an Amazon EC2 server and various Android clients.
