OSMlanduse.org + Remote Sensing = New conterminous land use data set for Germany released - filling gaps in OSM through machine learning
Posted in OSM, Publications, Services, VGI Group on Jan 19th, 2018
Land use data created by humans (OSM) was fused with satellite remote sensing data, resulting in a conterminous land use data set without gaps. The first version is now available for all Germany at OSMlanduse.org.
When human input (OSM data) was absent a machine generated missing land use information learning from human inputs and using remote [...]
Context-Based Classification of Urban Blocks According to Their Built-up Structure
Posted in Publications on Jan 16th, 2018
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
Posted in Publications, VGI Group on Jan 10th, 2018
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 [...]
Open land cover from OpenStreetMap and remote sensing
Posted in OSM, Publications, Services on Sep 27th, 2017
In a recently published study (1), we produced a web based land use land cover (LULC) product based on OSM tags which are constantly updated by contributors/volunteers, and present a Remote Sensing based solution when tags were absent for a test site. We harness the combined benefit of an open source and ever-growing machine generated [...]

Two talks on Tsunami Modeling ended GIScience Colloquium WS16/17
Posted in Events on Feb 16th, 2017
the GIScience Heidelberg colloquium series winter semester 2016/17 finished last week with even two presentations about Modeling Tsunami based risks and exposure. We were happy to hear first an overview from Andreas Schäfer vom KIT’s CEDIM about his PhD on Developing a Global Tsunami Risk Model. Thanks for our partners in the HeiKA CrowdFDA project [...]
Invitation: Colloquium Talk by Dr. Thomas Jarmer on Using Spectroscopy and hyperspectral imagery for the Assessment of Surface Properties
Posted in Events on Dec 16th, 2016
We cordially invite all interested to our forthcoming talk in the GIScience colloquium next Monday, December 19, about the use of remote sensing techniques for assessing soil and crop properties for applications in agriculture. Dr. Thomas Jarmer combines quantitative field measurements with remote sensing imagery to achieve not only a qualitative, but a quantitative assessment [...]
Invitation: Colloquium Talk by Jun.-Prof. Sven Lautenbach on Trade-offs Between Land use and Ecosystem Services
Posted in Events on Dec 9th, 2016
We cordially invite all interested to our forthcoming talk in the GIScience colloquium next Monday, December 12, about quantifying trade-offs between land use and ecosystem services. Jun.-Prof. Sven Lautenbach will provide an overview of methods to assess the different environmental goods and services produced by land systems. Policy makers are in want of such information to [...]
GIScience excursion to European Space Agency (ESA)
Posted in Events on Sep 16th, 2015
Recently the GIScience Research Group at Heidelberg University visited the European Space Operations Centre (ESOC) in Darmstadt, Germany, which serves as the main mission control centre for the European Space Agency (ESA) . The Centre is responsible for a range of activities and in particular operating planetary and solar missions, such as Mars Express and [...]
