Due to the advent of Volunteered Geographic Information (VGI), large datasets of user-generated Points of Interest (POI) are now available. As with all VGI, however, there is uncertainty concerning data quality and fitness-for-use. Currently, the task of evaluating fitness-for-use of POI is left to the data user, with no guidance framework being available which is why the research published in a recent paper proposes a generic approach to choose appropriate measures for assessing fitness-for-use of crowdsourced POI for different tasks.

Methods:
POI are related to the higher-level concept of geo-atoms in order to identify and distinguish their two basic functions, geo-referencing and object-referencing. Then, for each of these functions, suitable measures of positional and thematic quality are developed based on existing quality indicators.

Results:
Typical use cases of POI are evaluated with regards to their use of the two basic functions of POI, and allocated appropriate measures for fitness-for-use. The general procedure is illustrated on a brief practical example using data from Facebook and Factual.

Conclusion:
This research addresses the issue of fitness-for-use of POI on a higher conceptual level by relating it to more fundamental notions of geographical information representation. The results are expected to assist users of crowdsourced POI datasets in determining an appropriate method to evaluate fitness-for-use.

Studies based on information acquired by participative geographic approaches have sought to cope with emergency situations and disasters such as floods. However, the impact of these approaches to flood risk governance systems in order to understand these types of events as a complete risk cycle is still not clear. In a recent paper, we analyse the governance possibilities of using participative geographic information like volunteered and public participatory geographic information for flood risk reduction in the case of Santiago de Chile, a city which regularly experiences urban floods during rainy seasons. Based on in-depth interviews and document analysis, our study indicates that a relevant part of the current information used for flood risk reduction efforts is provided to local and regional authorities by the affected population. Though, local actors are not recognized by central agencies as valid agents for the production of official information. Moreover, there are neither instances of communication or deliberation with the community, which reduces the capacity of local actors to discuss possible solutions. Participative geographic instruments are seen as potential mechanisms to strengthen work relations among local actors and authorities, by enhancing new logics for producing and sharing information. The impacts for the current risk governance system though can be diverse depending on the participants’ level of commitment and the political relations between actors and agencies. Considered as merely data acquisition and analysis mechanisms, participative instruments reproduce the existing hierarchical top-down structures. Furthermore, local-based approaches can enhance local work, support local diagnostics and increase the decision capacity of citizens.

It is so simple even children can use it but helps humanitarian organisations like the Red Cross and Doctors without Borders to better plan and perform their humanitarian activities.
In many developing countries actual maps are missing but are urgently needed for effectively providing humanitarian aid to those in need.

When Medecins Sans Frontieres / Doctors Without Borders (MSF) responds to major disease outbreaks with mass vaccination campaigns, hundreds of teams have to cover enormous areas (as happened in the measles outbreak in the Democratic Republic of Congo last year). Now, with MapSwipe, we can give vaccination campaign coordinators a super-fast snapshot of where the population clusters are, helping them to send their teams to the locations where they are most needed to achieve maximum vaccination coverage.

Following up on the “Heidelberg Process” developed by the disastermappers heidelberg/ GIScience Research Group in collaboration with the MissingMaps team, the app enables collecting information regarding the location of residential areas using satellite imagery and a microtasking approach.
A first implementation as Web-Application using the Pybossa Framework and the Evaluation of the results through the GIScience Research Group Heidelberg established the foundation of the development of this mobile app.

The disastermappers heidelberg/ GIScience Research Group are supporting the MissingMaps project with Mapathons and by conducting research on the use of OpenStreetMap data for humanitarian aid. The app is a result of this collaboration which provides an example on how research, practice and humanitarian aid can be combined to develop more efficient workflows (see also: Herfort et al 2016).

Contributors are asked to mark map tiles and to thereby provide information regarding inhabited regions.
One tap hereby signifies that residential features could be identified, a second tap indicates the likeliness of features. A third tap flags tiles with bad image quality. If no features are visible you can just swipe to the next tile and go on with the task.
The App allows you to contribute online as well as offline, using satellite imagery that can be downloaded beforehand. Therefore the app allows you to contribute from home just as easy as on the commute. The provided information can be utilized by mappers to furthermore digitize building structures, roads and other individual features. That way base maps that support the work of MSF, the Red Cross and other organizations are developed in a collaborative workflow.

The official video of the research project “Multidimensional Perceptibility of Cultural Heritage (MUSIEKE)” has been released and can be watched here: https://youtu.be/s3-4Rzye22U

The project MUSIEKE aims at analyzing interrelations between perceptions and experiences of cultural heritage: in (1) museum environments, in (2) urban spaces and their spatio-temporal entanglements with the surrounding (cultural) landscape and in (3) virtual spaces. This comprises possibilities and limits of screening, viewing, projecting and experiencing cultural heritage. At the same time, the process of historic-archaeological research will be documented. The following steps and their interlock will be analyzed: assessment, measuring, vision, perception, and understanding. The basis of this work is the acquisition and processing of physical evidence into 3D-models, which requires their storage in interoperable file formats as well as enabling their access by the internet. Various fields in applied research and humanities rely on this technical process of preparing data and rendering it accessible. In turn, applied and basic research on the analysis of measured and evaluated data provide a deeper understanding of contexts, interpretations, meanings, and conflicts connected to the identification, analysis, processing and uses of cultural heritage. The Jupiter Column (Iupittergigantensäule) of Ladenburg will be used to test the interdisciplinary practices of making the various dimensions of cultural heritage perceptible. The Jupiter Column is an exemplary and representative object important for the rich cultural history of Ladenburg, a town with an impressive Roman history. Lessons learnt in this case study will be gathered in a joint research concept.

Social innovations are increasingly being seen as a way of compensating for insufficiencies of both, state and market to create inclusive and accessible environments. In a recent paper, together with researchers from Zentrum für Soziale Innovation (Vienna) and Polibienestar Research Institute (Valencia), we have explored crowdsourcing accessibility information as a form of social innovation, requiring adequate engagement strategies that fit the skills of the intended group of volunteers and ensure the needed levels of data accuracy and reliability. The tools that have been used for crowdsourcing included printed maps, mobile apps for collective tagging, crowdsourcing platforms on the web and blogs for reflection and visualizations of changing mapping statuses.

some time ago we deployed OpenFloodRiskMap (OFRM) at http://ofrm.geog.uni-heidelberg.de/

OpenFloodRiskMap (OFRM) is a prototype web application to assist decision makers in developing alarm and operation plans for flood risk management. The OFRM hereby provides support in accessing critical infrastructure (CI) information in the OpenStreetMap (OSM) data base and to furthermore add this information to an emergency routing service based on OpenRouteService.
In a disaster scenario decision makers need to be able to identify asset types of critical infrastructures as these objects are of specific interest for the community and thus, deserve special attention. While there are various frameworks containing definitions and categorizations regarding this concept, these documents do not contain object type catalogues listing these infrastructures on an object level. For this purpose, a catalogue of asset types of CI was already developed by Herfort et al. (Herfort, Eckle, Porto de Albuquerque, Zipf, 2015). In the OFRM, this catalogue serves as a preselection that enables identifying CI in OSM. In a flood scenario, decision makers have to moreover navigate to the CI objects, e.g. for evacuation or to provide security measures, while considering flood related road conditions. This kind of information cannot be considered in a general navigation system, nor can these systems detect CI objects.

Therfore ORS provides some specific functionality, such as:
- List of critical objects in OSM, sorted according to critical sector
- Print function for field use
- Direct transfer of critical objects to emergency routing query
- OSM Id editor link: editing of object in OSM data base
- Storage function for further use of query
- Define areas to avoid in routing through
…. a) Individual area, specified by user with drawing too
…. b) Integrated Flood Hazard Map layer to assist identifying bypass areas

In June, the State Key laboratory of Information Engineering and Surveying, Mapping and Remote Sensing (LIESMARS, http://www.lmars.whu.edu.cn/en/) launched their 2016 Geoinformatics Summer School at Wuhan University, China. This year’s courses treated topics ranging from technologies and paradigms for web mapping and online GIS to night-time remote sensing and GNSS. Participants from Africa, Europe and Asia, including three participants from Heidelberg University (two members of the Geoinformatics research group and one student of Geoinformatics), enjoyed ten days of excellent lectures, hands-on practice, and group project work in a highly innovative and multicultural setting. Geoinformatics Summer School at LIESMARS is held every year. It is a great opportunity to meet with students from all over the world, work together on new ideas, and widen your scientific as well as cultural perspective.
