Hyperspectral and LiDAR Fusion Using Deep Three-Stream Convolutional Neural Networks
Our feature paper “Hyperspectral and LiDAR Fusion Using Deep Three-Stream Convolutional Neural Networks” is now published online. Recently, convolutional neural networks (CNN) have been intensively investigated for the classification of remote sensing data by extracting invariant and abstract features suitable for classification. In this paper, a novel framework is proposed for the fusion of hyperspectral…

HeidelErg – live from the Erg Chebbi in Morocco (#6): Exploring physical geography and 3D GIScience in an aeolian sand dune field.
Yesterday, the practical field trip in the Erg Chebbi ended and the majority of the group arrived safely in Heidelberg. Another part of the group and the equipment are still on their way back via car and ferry. After several days in the field, we are already very excited to start working on the large…

HeidelErg – live from the Erg Chebbi in Morocco (#5): Exploring physical geography and 3D GIScience in an aeolian sand dune field.
On Thursday and Friday our group went further into the Erg in order to extend measurements from the last years on a large star dune arm and then spent one night in a dune camp. Yesterday was the last day of field work in the Erg.The TLS group completed the data acquisition on a star dune…

Deep Learning from Multiple Crowds: A Case Study of Humanitarian Mapping
Our paper about Deep Learning from Multiple Crowds: A Case Study of Humanitarian Mapping is available online now. Satellite images are widely applied in humanitarian mapping which labels buildings, roads and so on for humanitarian aid and economic development. However, the labeling now is mostly done by volunteers. In a recently accepted study, we utilize deep…

HeidelErg – live from the Erg Chebbi in Morocco (#4): Exploring physical geography and 3D GIScience in an aeolian sand dune field.
During the last three days of field work we not only acquired a lot of data at different sites in the Erg Chebbi. We also experienced various weather conditions including two sand storms, rain and sunny and hot days. Yesterday, one group measured ground control points for satellite and photogrammetric point cloud data with an…

Explore the ohsome OSM History of whole Germany
Our new ohsome dashboard is another preview on what is and will be possible with our ohsome OpenStreetMap history analytics platform. Behind the scenes, we added support for the Apache Ignite big data framework and deployed an instance using the full OSM history data of whole Germany on Heidelberg University’s cloud computing infrastructure heiCLOUD. Apache Ignite is an open-source…

HeidelErg – live from the Erg Chebbi in Morocco (#3): Exploring physical geography and 3D GIScience in an aeolian sand dune field.
Data acquisition in the Erg Chebbi has now started. In different groups several measurement techniques (drilling, electrical resistivity tomography, ground penetrating radar, sediment analysis, RTK GNSS, terrestrial laser scanning) were applied. Find some impressions in the pictures below.

openrouteservice elevation goes farther north than ever before
Last week we have been upgrading the openrouteservice, and with that has come the ability to include elevation information in routing pretty much anywhere on the globe (sorry people on Antarctica, but we don’t have routing for you just yet). So if you want to know the elevation and steepness of your drive from Svalbard…
