Special Issue: Frontiers in Earth Observation

European Journal of Remote Sensing

About this special issue

We live in a constantly and rapidly changing world. This is more than true for remote sensing technology and applications. Therefore, frontiers in Earth observation (EO) are also constantly moving ahead. This special issue presents the outcome of the 36th Symposium of the European Association of Remote Sensing Laboratories (EARSeL) that took place from 20-24 June 2016 in Bonn, Germany. The EARSeL symposia usually cover a wide range of topics, often beyond mainstream applications. Those events attract remote sensing experts from all over the world, in particular young scientists appreciating dedicated sessions and the opportunity to present their work. Thanks to the large amount of valuable contributions, we were able to compile this special issue reflecting frontiers of Earth Observation in Europe and beyond.

Overall, 18 peer-reviewed articles, covering a variety of topics from classical Remote Sensing applications such as land cover mapping to the cutting edge research in the area of EO education, constitute this special issue. The work published within this special issue opens new perspectives. Krtalic & Bajic introduce a new system that supports humanitarian demining activities. Schultz et al. showcase examples of the exploitation of videos taken at the international space station (ISS) for scientific and educational purposes – a rather uncommon EO application. Pratomo et al. assess the transferability of object-based image analysis (OBIA) methods to detect slums in Jakarta, Indonesia, based on very high resolution (VHR) Pléiades imagery. Mustafa et al. assess machine learning and logistic regression for the calibration of cellular automata land use change models to predict urban expansion patterns and their major determinants. The work by Landier et al. contributes to a better understanding of the radiative budget of urban environments by using a 3D radiative transfer model. Urban climate is also addressed by Wicht et al. They explore urban ventilation corridors based on 3D SPOT data. Lang presents an innovative approach to valuate urban green infrastructure. Urban vegetation is also addressed by Kothencz et al. who extract different vegetation height classes from stereo and tri-stereo VHR images in two European cities. Di Rita et al. present the FOSS4G DATE approach for digital surface model (DSM) generation based on tri-stereo optical VHR images.

Land cover and land use assessment increasingly takes advantage of multi-temporal and multi-sensoral imagery. Gazaryan et al. demonstrate the use of multi-sensor datasets (Landsat, Sentinel-1 and Sentinel-2) and machine learning algorithms for crop mapping over large areas. Multi-temporal data was used by Basukala et al. and Hütt & Waldhoff to classify crop types on smaller scales. Basukala et al. used Landsat-8 data whereas Hütt & Waldhoff take advantage of multi-temporal dual-polarized TerraSAR-X radar images. Dubovyk reviews the role of remote sensing for land degradation assessments and discusses its challenges and opportunities. Makinde et al. use remote sensing and geospatial techniques to estimate the amount of carbon sequestered in an afforestation project in Nigeria.

Sabat-Tomala et al. demonstrate the usability of airborne hyperspectral remote sensing in combination with hydrodynamic modelling for the assessment of lake water quality. Benabadji et al. developed an unsupervised hyperspectral band selection method, which is important for dimensionality reduction in large hyperspectral datasets. Toulia et al. present a case study that shows the potential of pattern recognition in geomorphology and geology. Nikolakopoulos et al. demonstrate how the synergy of multi-disciplinary surveys can contribute to improved active landslide monitoring.

The variety of EO application and methodology united in this special issue exemplifies some of the frontiers of EO. The 36th EARSeL Symposium in Bonn was organized by the Remote Sensing Research Group (RSRG) at the Department of Geography and the Center for Remote Sensing of Land Surfaces (ZFL) of the University of Bonn under the guidance of Prof. Gunter Menz and Prof. Klaus Greve. Gunter Menz passed away shortly after the symposium. With this special issue, we would like to commemorate his great achievements in promoting research and education in the field of Earth Observation.
