Special Issue “Earth Observation and Geoinformation Technologies for Sustainable Development”
Dear Colleagues, Earth observation devices and geoinformation technologies, including remote sensing data, platforms, algorithms, geographic information science (GISc), and spatial analysis techniques have played a major role in monitoring the dynamics of our environment and landscape. Additionally, emerging active and passive sensing approaches, such as crowdsourcing, Volunteered Geographic Information (VGI), citizen science (CS), participatory sensing,…

Modeling the evolution of OpenStreetMap with Cellular Automata using a new VGI Contribution Index
Major research efforts have so far dealt with OSM data quality analysis, but the modality of the evolution of OpenStreetMap (OSM) across space and time has been barely noted. Therefore, a new study by Jokar Arsanjani et al. that has recently been accepted for publication in Transactions in GIS aims to analyze spatio-temporal patterns of…

Twitter location (sometimes) matters
In contrast to photo-based VGI (e.g. Flickr) the correlation between the place where an information has been created and what the information is about is less intuitive for text-based VGI. In order to gain more insight into the relationship between text information generated in mobile contexts (e.g. via smartphones) and their recorded location, research has…

Geographic information analysis and web-based geoportals to explore malnutrition in Sub-Saharan Africa
In our new paper we present a systematic literature review on geographic information analysis and web-based geoportals to explore malnutrition in Sub-Saharan Africa. 563 articles are identified from the searches, from which a total of nine articles and eight geoportals meet inclusion criteria. The review suggests that the spatial dimension of malnutrition is analyzed most…

Ravenstein-Förderpreis 2014 for automated map labelling
Two our colleagues, Maxim Rylov and Andreas Reimer have received a Ravenstein Recognition award from the German Cartographic Society. Their work in automation of map lettering has been recognized by jury members as a compelling and relevant topic that is undoubtedly interesting to all who concerns oneself with digital cartography. Their considerable achievements are the…
