Context-Based Classification of Urban Blocks According to Their Built-up Structure
A recently published paper presents an approach for classifying urban blocks according to their built-up structure based on high-resolution spaceborne InSAR images. Most attributes considered in the classification describe the geometric structure and spatial disposition of the polygon and line features extracted from each block. The feature extraction is carried out on two intensity images…

Deep Learning with Satellite Images and Volunteered Geographic Information
Recently, deep learning has been widely applied in pattern recognition with satellite images. Deep learning techniques like Convolutional Neural Network and Deep Belief Network have shown outstanding performance in detecting ground objects like buildings and roads, and the learnt deep features are further applied in some prediction tasks like poverty and population mapping. On the…

Digital Geoarchaeology: New Techniques for Interdisciplinary Human-Environmental Research
Digital Geoarchaeology can be regarded as an intersection of disciplines that contributes to the consolidation of different academic perspectives. It represents a novel approach in terms of computer scientific methods combined with geoscientific know-how and archaeological expertise to multi-methodically investigate past human-environmental relationships (Siart et al. 2018). In the new textbook “Digital Geoarchaeology” by Springer,…

Routing through open spaces – a performance comparison of algorithms
Finding the shortest path through open spaces is a well-known challenge for pedestrian routing engines. A common solution is routing on the open space boundary, which causes in most cases an unnecessarily long route. A possible alternative is to create a subgraph within the open space. In a recently published paper authors from GIScience Research…

Cover Story of ISPRS International Journal of Geo-Information
Not undercover but on the cover: We were selected as cover story of the ISPRS International Journal of Geo-Information, Volume 6, Issue 11. In our research on “Historic Low Wall Detection via Topographic Parameter Images Derived from Fine-Resolution DEM“, we apply rapid landscape line detection to extract historic vegetable garden walls based on topographic information…

3rd CFP: Special Issue “Crowdsourcing for Urban Geoinformatics”, Deadline End of Nov 2017, Open Access by Taylor & Francis, no publishing costs
Crowdsourcing for Urban Geoinformatics Aims and Scope Modern mobile devices are pervasively equipped with embedded sensors and cameras, and allow the positioning of media contents within geographic space. In combination with the Web 2.0 paradigm, this has led to the crowdsourcing approach, which in turn has become an important data acquisition technique. It is now…

The impacts of environmental factors on cycling behavior
As it is widely accepted, cycling tends to produce health benefits and reduce air pollution. Policymakers encourage people to use bikes by improving cycling facilities as well as developing bicycle-sharing systems (BSS). It is interesting to investigate how environmental factors influence the cycling behavior of users of bicycle-sharing systems, as users of bicycle-sharing systems tend…

Mobile low-cost 3D camera maize crop height measurements under field conditions
Maps of the spatial distribution of crop heights can strongly support agriculture in terms of efficiency and yield optimization. Recently published results of experiments of the 3D Spatial Data Processing research group describe an approach to easily extend regular agricultural machines with low-cost sensors for capturing crop heights while the machine is in the field.…
