Open Data Revolution of the Deutsche Bahn (German Railways)

Deutsche Bahn (German Railways), one of the world-leading passenger and logistics company is long-known to be very closed and conservative. Therefore, for many it was a complete surprize when Deutsche Bahn has announced the DB Open Data Portal in Novemeber 2015 and started publishing datasets under very permissive Creative Commons licenses. These datasets include geodata like stops, stations, complete railway track network and many others, growing almost weekly. DB Open Data is now extended by DB Open APIs like timetable of the long-distance trains. In this talk, we tell the story behind DB Open Data. About our challenges and failures, our successes and lessons learned on the way to become more open, to enable and to be enabled by the community. We show projects which were already implemented using our Open Data and point out to boundaries we still have to break.

OpenSource tools for water network management

This presentation details some OpenSource tools dedicated to water network management, be it for water distribution or wastewater networks. The qWAT project is a specific tool based on QGIS and PostGIS. it aims at managing water distribution networks. The data model is part of the project and covers most use cases for this kind of assets. The qWAT project is strongly linked to QGIS, and tries to contribute to the core of QGIS so as to mutualize developments and features among other QGIS-based applications. Similarly, the QGEP project is dedicated to wastewater networks. We also present a use case for an implementation of a wastewater information system in France, based on QGIS and PostGIS. Furthermore, we show how PostGIS-based projects allow to do network and graph analysis, so as to extract meaningful information for decision-taking and planning. QGIS-Epanet and QGIS-SWMM are two QGIS Processing extensions integrating simulation features on water distribution and wastewater networks. They let the user run simulations to analyze the network, dimensioning, and identify specific issues. These set of tools show that OpenSource GIS now tend to fulfill use cases for specific fields of application, and water management is among them.

GeoServer Styling Hints and Tips for Prettier Maps

Web maps needn't be dull and this talk will show you how you can take your cartographic skills from the desktop GIS to the web using SLD and GeoServer. The initial part of the talk will introduce desktop tools such as QGIS and UDig and how they can help novices get started with styling maps. Moving beyond the basics it will continue with a look at the use of functions to modify the features being drawn. It will include an in depth look at how to control the placement of labels to enhance the readability of the map especially when using tile caching to speed up map service. The talk will finish with a discussion of using GeoServer's composite and blending modes to provide pretty effects that can enhance your web mapping.
