14.04.2015	The place of Geoinformation in education: turning mobile and …moving forward!	Vania Carlos	Universitade Aveiro
	Main topics: What´s the trend for the use of Geoinformation/Geospatial technologies – where are we in terms of its use in education? Mobile learning and Geogaming as hot topics in education; Teacher training in Geospatial Technologies – challenges and principles for its integration in classroom; Geospatial technologies added value for the development of student’s critical spatial thinking skills.
21.04.2015	What are the user requirements for GI Science?	Michael Gould	Esri education outreach (USA) and University Jaume I (Spain)
	This talk relates 25 years of experience as both GI Science researcher and manager at a commercial GIS software company, using user requirements as a key. Are societal expectations changing regarding the practice and results of scientific research? Why is GI Science practiced only in the rich (developed) world? How might we do a better job at harmonizing societal problems and scientific research?
28.04.2015	From Maps to Geomedial Action Spaces – Theoretical and Methodological Considerations of Contemporary Mapping Practices	Pablo Abend
	The increased networked digital distribution of geographic information for consumer-orientated cartographic representations leads to substantial changes in how people individually and collaboratively experience and produce space and place. Maps change from offering static and non-interactive frames of geographic reference for the production of space and place to support a veritable infinity of interactive and map-based activities associated with geomedia. The talk addresses significant questions in geography and cognate fields about the future roles of maps in the information age drawing on a qualitative analysis on the usage of the most widely used type of consumer software Google Earth. The usage practice termed geobrowsing, in particular, facilitates new modes of interaction that move from logocentric engagements with static maps to egocentric dynamic interactions with code-based elements of geomedial action spaces. The talk focuses on this ongoing metamorphosis seen in geobrowsing, the media-based flexible production of geographic knowledge through interactive maps. Drawing on work in media studies influenced by the so-called spatial turn – the engagement with geography-related questions in the social sciences and humanities –, a theoretical framework is introduced built on the concept of geomedial action spaces to understand the changing roles of information age maps as imagined materialist spaces for the experience and production of space.
05.05.2015	Legal aspects of crowd sourcing	Franziska Boehm	WWU
	The talk will introduce the audience to legal principles following from European law, which have to be considered in crowd sourcing projects. It will focus on the legal requirements of data protection and its impacts on crowd sourcing. The aim is to show what kind of information is categorized as personal data and which guidelines and legal principles have to be respected by the different parties involved. Furthermore, basic aspects of copyright law and its challenges on crowd sourcing will be explained and shown which data are protected by copyright and how legal requirements in this context can be respected. The talk shall inform the audience which legal requirements need to be taken into account when dealing with crowd sourced data and how to avoid possible legal difficulties in related projects.
12.05.2015	Data, Concepts and Models of a Spatial Data Science by linking Geography, GI-Science and Data Analytics	Peter Mandl	Klagenfurt
	In three small chapters, some aspects of an emerging "Spatial Data Science", are presented. For that insights and concepts from GIScience, geography and data analytics are linked. First some components of these three linked research fields are presented and their advantages and risks are discussed. From GIScience concepts of the semantic web, linked open data and geodata modelling are taken. From geography concepts of location analytics, spatial data mining and visual analytics for the analysis and prediction of spatial phenomena are used. From data analytics methods, which were used in quantitative geography many years ago, are taken and are extended by visual, predictive, prescriptive and explorative aspects. These components are linked into a framework for a Spatial Data Science, which is delineated in the second part. Some research questions and applications are discussed. In the final part some recent applications are shown. The presentation shows first ideas for an integrated approach within the "4th scientific paradigm of an e-science" or in a "data-driven geography" (acc. to Miller and Goodchild 2015) to solve spatio-temporal problems using established and new tools coming from the three linked research fields.
19.05.2015	"here" - digital map data for turn-by-turn navigation	Eric Oeder, GeoAnalyst	HERE Germany
	Here is the worldwide leading provider of digital map data for turn-by-turn navigation, maps in the internet and for business solutions . Here-Regional offices exist in all continents. GeoAnalysts are responsible for creating and updating the map permanently. The presenter, also a GeoAnalyst, shows how the data is collected and how it is entered in the GIS-database of Here. One new approach is the cooperation with external Communities (like universities) which use the so called Map Creator of Here.

16.06.2015	Towards Ad-Hoc Collaboration Spaces with Cross-Device Interaction Techniques	Nicolai Marquardt	University College London
	Despite the ongoing proliferation of devices and form-factors such as tablets and electronic whiteboards, technology often hinders (rather than helps) informal small-group interactions. Whereas natural human conversation is fluid and dynamic, discussions that rely on digital content — slides, documents, clippings — often remain hindered due to the awkwardness of manipulating, sharing, and displaying information on and across multiple devices. Addressing these shortcomings, in this talk I present our research towards fluid, ad-hoc, minimally disruptive techniques for co-located collaboration by leveraging the proxemics of people as well as the proxemics of devices. In particular, I will demonstrate a number of cross-device interaction techniques—situated within the research theme of proxemic interactions—that support nuanced gradations of sharing. I will also introduce different novel hybrid sensing approaches enabling these interaction techniques and discuss future research directions.
23.06.2015	Processing and Understanding Geo-Social Media Content	Frank Ostermann	U Twente
	Geo-social media content is known under many names, including user-generated geographic content, ambient geographic information, or volunteered geographic information. In this talk, I will highlight practical issues in handling and understanding geo-social media content, as well as fundamental issues relating to scientific validity and societal challenges. Recent research examples aim to illustrate potential solutions, including near real-time processing of crisis-related Tweets and Flickr images, automated enrichment of geo-located photographs, and extraction of place semantics from combined Twitter and Flickr clusters.
30.06.2015	Modelling Schematisation: From Aesthetics to Algorithms	Andreas Reimer	Uni Heidelberg
	For many applications, maps are the most effective visualisation of geographic phenomena. Automated map generation, once thought to be impossible, has celebrated great successes in recent years. These successes were concentrated on large-scale topographic map production and roadmap-style web-maps. Many occasions warrant the provision of easy-to-read geovisualisations. Schematised maps are one sub-category that can display a geographic overview succinctly. Previous efforts in schematisation research were especially successful when the crucial design specifications were well understood and properly formalised. When these preconditions were met, algorithmic and technical refinement could take over. In this talk we investigate several areas of cartographic design specifications that have so far been mostly neglected. Examples are chorematic diagrams, Merkbilder and similar thematic schematised maps. The talk will investigate several strategies of moving from observations and aesthetic principles toward geometric algorithms. We close with a discussion on our research on Stenomaps, which widen the cartographic design-space by schematising areas into curves.
07.07.2015	Conflict Avoidance in Automated Cartography Using Mathematical Programming	Jan-Henrik Haunert	Osnabrück
	Computational problems in cartography include map generalization, label placement, and map distortion, e.g., to enlarge a region of interest in a map. The existing algorithmic solutions to these problems often cause spatial conflicts. For example, lines may intersect after simplification, labels may overlap, and non-contiguous areas may arise when smaller areal units are aggregated. Mathematical programming is an optimization approach that is very capable in handling constraints and thus in avoiding the above-mentioned spatial conflicts in cartography. In my talk, I will discuss applications of convex quadratic programming and integer linear programming. While convex quadratic programming can be solved efficiently, integer linear programming is NP-hard. Nevertheless, it allows small problem instances to be solved exactly. This can be used to derive benchmarks of cartographic quality for efficient heuristic (i.e., inexact) algorithms.
