Multisource and Multitemporal Data Fusion in Remote Sensing: A Comprehensive Review of the State of the Art
The recent, sharp increase in the availability of data captured by different sensors, combined with their considerable heterogeneity, poses a serious challenge for the effective and efficient processing of remotely sensed data. Such an increase in remote sensing and ancillary data sets, however, opens up the possibility of utilizing multimodal data sets in a joint…

Brand new 3DGeo logo!
The 3DGeo research group has now a brand new 3DGeo logo! The logo is one result of our recent retreat to Lochau. And here it is: The creative “o” represents the process from raw 3D data via various data models to real-world phenomena – or vice versa. Isn’t that cool? Check out the logo on…

Teaching geodata acquisition in and around Heidelberg
As part of the lecture “Geodatenerfassung”, geography students in their first semester turned theory of digital geodata acquisition into practice. Based on their aims and requirements, the students acquired geodata with different methods and sensors. Using a high-end Riegl VZ-2000i terrestrial laser scanner, two groups captured the old town of Heidelberg and a limestone quarry…

SYSSIFOSS – Synthetic structural remote sensing data for improved forest inventory models
Airborne light detection and ranging (LiDAR) data provides reliable information on forest structure. Related forest inventory approaches recently evolved into operational tools. Today, further optimization of existing approaches is pursued to ensure high data quality of the inventory information and cost-efficiency over varied environmental and silvicultural conditions. Synthetic LiDAR data has been suggested as useful…

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 (#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…

HeidelErg – live from the Erg Chebbi in Morocco (#2): Exploring physical geography and 3D GIScience in an aeolian sand dune field.
After the participants of the practical field training had arrived in Fès yesterday and spent the evening there, the group is now on the way to the Erg Chebbi east of the Anti-Atlas mountains. Thereby, the group passes various gemorphologic landscape units including the Western Meseta, Middle Atlas and High Atlas mountains. Moreover, we crossed…
