PLATIAL’18 Workshop in September
The recent availability of user-generated geographic datasets allows gaining novel insights into otherwise hardly observable societal phenomena. Geosocial media forms one important source of user-generated information, which partly describes the everyday lives of people. The analysis of these kinds of data, however, requires new approaches. Geosocial media data—like those extracted from Twitter, Flickr, Instagram, and…

Your support for MAnnheimer MAPAthons (MAMAPA)
Beginning of May the recently launched MAMAPA project reached yet another milestone. Four very successful MAMAPA mapathons were already organized in the Mannheimer Abendakademie, supported by CartONG, HeiGIT/ disastermappers heidelberg and local tandems, and there are hopefully many more to come… To build a sustainable future for the MAMAPA project, members of HeiGIT, CartONG and…

A discussion of crowdsourced geographic information initiatives and big Earth observation data architectures for land-use and land-cover monitoring
The effective monitoring of land-use and land-cover changes (LULCC) is a basic requirement for understanding socio-enviromental processes of local to global scales. Remote sensing data and methods have long been established as the most effective approach for monitoring LULCC. The potential for further increasing the effectiveness of this approach is proportional to the astonishingly large…

Ohsome for Street Network Analysis and Disaster Activation Monitoring
Disaster mapping activations that are supported by many volunteers with various levels of experience raise questions related to the quality of the provided Volunteered Geographic Information. Learning about the data quality that can be expected in a disaster activation helps to evaluate the quality and fitness for purpose of the OSM data. At the ISCRAM…

Identifying the Effects of Mobility Domains on Volunteered Geographical Information: Towards an Analytical Approach
The production of Volunteered Geographic Information (VGI) is a type of human behavior which emerges via direct and indirect interactions with the physical environments described by these data. The nature of these interactions and the extent to which they rely on physical presence in the mapped area may affect the quality of the resulting digital…
