GIScience Research Group Heidelberg becomes Member of the Missing Maps Project

GIScience Research Group Heidelberg becomes Member of the Missing Maps Project The GIScience Research Group at Heidelberg University is happy to announce their official membership in the Missing Maps Project . The objective of the Missing Maps Project is to map the most vulnerable places in the developing world, in order that international and local NGOs and individuals can use the maps and data to better respond to crises affecting the areas. Also it aims at supporting OpenStreetMap , specifically the Humanitarian OpenStreetMap Team (HOT), in developing technologies, skills, workflows, and communities. The humanitarian mapping project is an open collaboration founded by Humanitarian OSM Team (HOT), Medecins Sans Frontieres/Doctors Without Borders (MSF), American Red Cross and the British Red Cross . Apart from these founding members, cartONG, the Netherlands RedCross and the Clinton Health Access Initiative support the project as formal members. Now the GIScience Research Group Heidelberg University with disastermappers heidelberg became the fourth additional member of the collaboration. GIScience Heidelberg is dedicated to support the work of the Missing Maps Project through several activities related to research & development, teaching & outreach (Mapathons) etc. The GIScience Research Group Heidelberg University has a long time experience regarding crowdsourcing and Volunteered Geographic Information (VGI). Thus, OSM data quality assessments and the usage of OSM data for (emergency) routing or in disaster management (e.g identifying critical infrastructures) are core topics of the research group since several years and will continue to be an active area in research, development and teaching. Since the launch of the Missing Maps project, the disastermappers heidelberg and GIScience Heidelberg organized several joint activities like Missing Maps Mapathons and practical workshops. These activities led to a closer cooperation with the Missing Maps team. For example a multi-step workflow was developed conceptually and implemented technically by the disastermappers heidelberg in cooperation with the MissingMaps team to facilitate the work of the volunteers. This is the base for the new mobile MicroTasking App being developed by Missing Maps right now. We are looking forward to working together with the Missing Maps Project putting the worlds vulnerable people on the map. http://www.missingmaps.org http://uni-heidelberg.de/gis Founders MembersGIScience Research Group Heidelberg becomes Member of the Missing Maps Project

Assessing the suitability of GlobeLand30 for mapping land cover in Germany

Assessing the suitability of GlobeLand30 for mapping land cover in Germany A new publication on the suitability of the new global land cover map of 2010 called GlobeLand30 for mapping European landscapes in particular, Germany and a cross comparison with crowdsourced and authoritative datasets. Abstract: Global land cover maps have been widely employed as the base layer for a number of applications including climate change, food security, water quality, biodiversity, change detection and environmental planning. Due to the importance of land cover, there is a pressing need to increase the temporal and spatial resolution of global land cover maps. A recent advance in this direction has been the GlobeLand30 dataset derived from Landsat imagery, which has been developed by the National Geomatics Center of China (NGCC). Although overall accuracy is greater than 80%, the NGCC would like help in assessing the accuracy of the product in different regions of the world. To assist in this process, this study compares the GlobeLand30 product with existing public and online datasets, i.e. CORINE, Urban Atlas, OpenStreetMap and ATKIS for Germany in order to assess overall and per class agreement. The results of the analysis reveal high agreement of up to 92% between these datasets and GlobeLand30 but that large disagreements for certain classes are evident, in particular wetlands. However, overall, GlobeLand30 is shown to be a useful product for characterizing land cover in Germany, and paves the way for further regional and national validation efforts. For further information check this out. Jokar Arsanjani, J., See, L., Tayyebi, A.

Amateur or Professional: Assessing the Expertise of Major Contributors in OpenStreetMap Based on Contributing Behaviors

Amateur or Professional: Assessing the Expertise of Major Contributors in OpenStreetMap Based on Contributing Behaviors Volunteered geographic information (VGI ) projects, such as OpenStreetMap (OSM ), provide an alternative way to produce geographic data. Research has showed that the resulting data in some areas are of decent quality, which guarantees their usability in various applications. Though these achievements are normally attributed to the huge heterogeneous community mainly consisting of amateurs, it is in fact a small percentage of major contributors who make nearly all contributions. In addition to their recent work on temporal analysis of contribution inequality in OpenStreetmap in an new paper, A. Yang et al. (2016) investigate the contributing behaviors of these contributors to deduce whether they are actually professionals. Various indicators are used to depict the behaviors on three themes: practice, skill and motivation, aiming to identify solid evidence for expertise. The case studies show that most major contributors in Germany, France and the United Kingdom are hardly amateurs, but are professionals instead. These contributors have rich experiences on geographical data editing, have a decent grasp of professional software and work on the project with enthusiasm and concentration. It is less unexpected that they can create geographic data of high quality. Three features distinguish this work from previous efforts. Firstly, there is a focus on major contributors, so the results can illustrate whether most OSM data come from professionals well. Secondly, they deliberately discuss expertise and use various guidelines to ensure inferential strength. Finally, though some classical indicators, such as total contributions and longevity, are still used in the work, more innovative indicators to depict expertise from various aspects are being introduced. The approach provides a possible way to examine the expertise of contributors when direct knowledge of individuals is not available, which usually is the case due to the anonymity of OSM users. The indicators introduced in this paper can also be useful for intrinsic OSM data quality analysis like Barron et al. 2013 or related work and recent frameworks . Data created by professional contributors should be more trusty and can be used as references to infer the quality of other data. Yang A., H. Fan, N.

2nd Call for Papers: Link-VGI Workshop @ AGILE Helsinki in June; Deadline April 25th.

2nd Call for Papers: Link-VGI Workshop @ AGILE Helsinki in June; Deadline April 25th. LINKing and analyzing Volunteered Geographic Information (VGI) across different platforms Pre Conference Workshop at 19th AGILE International Conference on Geographic Information Science 2016. Helsinki, June 14th 2016 Deadline for Call for Short Paper (AGILE short paper format): April 25th 2016 The number of Volunteered Geographic Information (VGI) and social media platforms is continuously growing, providing massive datasets of georeferenced content that is either actively contributed (e.g. adding data to OSM, Mapillary, or Flickr) or collected through more passive modes (e.g. enabling geolocation in Twitter feeds). Whereas contribution behavior for individual crowdsourcing applications has already been extensively analyzed in the literature, it is less understood if and how users participate in several crowd sourcing activities. Hence several research questions relevant to a better understanding of community involvement in data contributions have evolved. These include for example, whether activity spaces in different sources are spatially co-located or spatially distinct for individual contributors, or whether contributor communities evolve across platforms. As an example, users started to cross-link data from different platforms, e.g. by mapping OSM point of interests (POIs) and street features (e.g. street lamps, sidewalk information) based on Mapillary photographs, or by tagging Flickr pictures with OSM tags. This workshop provides an opportunity for interested researchers to share ideas and findings on cross-platform data contributions. One portion in the workshop is dedicated to a hands-on session. In this session, basics of spatial data access through selected APIs and the extraction of summary statistics of the results will be illustrated. The workshop shall focus, but is not limited to, the following topics and areas of research: User contribution patterns and data sharing across multiple VGI and social media platforms Accessing and visualization of VGI data from various platforms Understand differences in spatial/temporal coverage of contributions to different platforms Understanding how data are linked across different VGI/social media platforms What types of communities are evolving and emerging from VGI/social media platforms Investigating how cross-linked data are used in real-world applications Describing the effects of the growing number of VGI and social media on data quality and user behavior Assess the quality of cross-linked VGI Identifying current research questions and an emerging research agenda Programme Committee Vyron (Byron) Antoniou, University College London, UK Padraig Corcoran, Cardiff University, UK Brent Hecht, University of Minnesota, United States Hartwig Hochmair, University of Florida, United States Peter Mooney, Maynooth University, Ireland Dieter Pfoser, George Mason University, United States Ross Purves, University of Zurich, Switzerland Georg Gartner, TU Vienna, Austria Enrico Steiger, University of Heidelberg, Germany Jamal Jokar Arsanjani, University of Heidelberg, Germany Bernd Resch, University of Salzburg, Austria Adam Rousell, University of Heidelberg, Germany Hongchao Fan, University of Heidelberg, Germany Alexander Zipf, University of Heidelberg, Germany IMPORTANT DATES April 25th 2016 - Call for short papers ends.

HeiMAP - a virtual research platform for historic maps in the humanities

HeiMAP - a virtual research platform for historic maps in the humanities Recently a new project “HeiMAP ” has been funded at Heidelberg University. The goal of HeiMAP is the development of an online research platform with modular tools and services for project and data management especially for the collaborative work with and on predominantly historical maps and geographic information in the humanities. Maps contain multiple layers of information about past and contemporary geographies. To make scientific use of the embedded geographic information interdisciplinary collaborative work with high demands on internal communication, efficiency and interdisciplinary multimedia data management are required. The envisioned virtual research environment shall allow researchers from the humanities to work on digitized (historical) maps and spatial data. It shall provide the possibility to find solutions for a number of urgent problems in humanities research questions using geographical information: orientation in pre-modern space through exploitation of historical maps, active research on maps, working together online instead of working with desktop applications with high entry barriers and accessibility. By focusing on core functions and target group-oriented documentation, close connection with the services of the university library, rights management and proof of provenance, standard compliance of the developed geodata by assisted data modeling, long-term storage, propagation and reimportation of records with respect to new questions. The core of the project is a web-based Geographic Information System (WebGIS). The modular design of the system and compliance with international standards ensure a flexible connection to a web portal, which connects several tools and services, such as database systems for storing the metadata (with interfaces to external databases), various communication and organization tools, a central data store, a forum and various project managemenent tools. The inter-site and secure use of all tools is guaranteed by the identity management from bwIDM. The GIS module is connected to the Heidelberg research data repository heiDATA, whereby the publication of scientific data can be done (with DOI), thus improving the reuse possibilities of scientific results. Partners at Heidelberg Universit y include: - Computing Center (URZ) Heidelberg University - Exzellence Cluster “Asia & Europe in a Global Context” - Institut für Fränkisch-Pfälzische Geschichte und Landeskunde - GIScience Research Group, Institute of Geography - University library Heidelberg External partner: - Landesarchiv Baden-Württemberg.HeiMAP - a virtual research platform for historic maps in the humanities

This Wednesday Talks on Travel Impedance and Dynamics of Health-Related Tweets by Prof. Eric Delmelle

This Wednesday Talks on Travel Impedance and Dynamics of Health-Related Tweets by Prof. Eric Delmelle The semester has come to an end but still we are happy to invite you this to two open colloquium talks by Dr. Eric Delmelle, Associate Professor , Department of Geography & Earth Sciences, University North Carolina Charlotte about the two interesting topics: “Evaluating Travel Impedance Agreement among Online Road Network Data Providers” & “Visualizing the dynamics of health-related tweets: opportunities and computational challenges” The talks will be on this Wednesday Feb 17, 2016 4.15 pm-5.15.pm Hörsaal Berliner Straße 48 , Institute of Geography, Heidelberg University. Evaluating Travel Impedance Agreement among Online Road Network Data Providers Online mapping providers offer unprecedented access to spatial data and analytical tools; however the number of analytical queries that can be requested is usually limited. As such, providers using Volunteered Geographic Information (VGI) offer a viable alternative, given that the quality of the underlying spatial data is adequate. In this presentation, I will present results of an analysis aimed at assessing the agreement in travel distance estimates between Mapquest Open–which embraces OpenStreetMap (OSM) data, a VGI dataset-, and two other popular commercial providers, namely Google Maps™ and ArcGIS™ Online. We use a routing service Application Program Interface (API), to estimate travel impedance and the average number of OSM contributors. Origin-destination pairs are simulated for the state of North Carolina, U.S.A., and travel estimates reported for each of the providers. Results suggest (1) a strong correlation among all three road network providers, (2) agreement improves with increasing route distances and (3) decreases in areas with denser road network as providers may select different routes from a larger number of potential paths. Most importantly, travel estimates from Mapquest Open exhibit stronger similarity with both commercial providers when the average number of OSM contributors along the selected path is larger. Visualizing the dynamics of health-related tweets: opportunities and computational challenges Twitter, a form of social media, provides endless opportunities for public health. Information on disease symptoms, generated by twitter users, may alert health officials on the risk posed by a certain disease before it can be detected and officially confirmed in a lab. Certain tweets are georeferenced, and coupled with their temporal stamps, they have the potential to be used for space-time monitoring of diseases. This is particularly important to better understand disease dynamics, such as seasonality, direction, intensity and risk of diffusion to new regions. In this presentation, I will focus on the computational challenges associated to infer meaningful information from twitter related data, with an application to pollen-related tweets. I will then discuss a space-time framework to visualize the intensity of collected tweets in both space and time. I will discuss the impact of positional, temporal and attribute accuracy on the detection of space-time clusters from health-related tweets.This Wednesday Talks on Travel Impedance and Dynamics of Health-Related Tweets by Prof. Eric Delmelle
