High-end survey capacities at GIScience for research and teaching in and around Heidelberg
At the chair of GIScience, highly accurate RTK GNSS surveying is used for teaching and research. In the area in and around Heidelberg, surveys within the same coordinate reference system are now possible thanks to a fixed point recently installed by the group on the top of a university building. Teaching projects similar to the…

3D-MicroMapping of Big 3D Geo-Datasets in the Web (3D-MAPP)
Our new research project 3D-MAPP develops a web-based methodology to obtain digital geodata via the combination of data analysis by human and machine. Through a quick and easy-to-use 3D Web visualization users are able – in a few seconds – to solve 3D micro mapping tasks, which can hardly or even not be solved by…

Matching OpenStreetMap Road Networks with Authority Data – a Polygon-based Approach
Matching road network is an essential step for data quality assessment by using reference data. Conventionally, road network from two data sets are matched by using line-based approach which checks the similarity of properties of line segments. In new method recently published in IJGIS, a polygon-based approach is proposed to match OpenStreetMap road network with…

Being a Polar Researcher
Mid of October Inga Beck was invited by a local primary school to talk about her research and to give the students an impression about the work of a Polar Researcher. The entire school (around 200 children and 15 teachers) gathered in the assembly hall of the school and listened carefully to the presentation. Beside…

Statistical investigation of geo-tagged shipping information
Inspection and analysis of geo-tagged shipping information could provide insights to the transformation of a variety of “global spaces” during times of rapid globalization. One of the famous resources of shipping data is a shipping newspaper called LLOYDS lists. The list contains weekly and later daily information on global shipping since the late seventeenth century…

New Collaboration on Crowdsouring for Forensic Disaster Analysis with KIT
The aftermath of disasters – such as the recent Nepal earthquake – have shown that the general public can contribute to the response of a disaster event and moreover is able to organize and engage itself across national borders. Digital volunteerism is offering unique capabilities to bridge information gaps, particularly in crisis situations where infrastructure…

Exploring spatiotemporal and semantic clusters of Twitter data using unsupervised neural networks
The investigation of human activity patterns from location-based social networks like Twitter is a promising example of how to infer relationships and latent information for the characterization of urban structures. While there is a growing research body performing spatial analysis on social media data, the high dimensionality, complexity and granularity of social media information still…

Merging volunteered and expert accessibility data
On Tuesday 13 October, we have been more than happy to host volunteers of SAP in the course of the “SAP month of service” as our guests. They have supported us to merge volunteered data about accessibility from wheelmap.org and expert data about accessibility from Heidelberg Hürdenlos (a local accessibility platform). Heidelberg Hürdenlos contains more…
