Close-range sensing including 2D and 3D imaging and laser scan techniques is one of the most dynamically developing methods for data acquisition in the field of Geoscience. It extends the operational range, scale, and enhances traditional measurement techniques in terms of radiometric, spectral, spatial and time resolution. New developments in software and sensor technology enable for example dynamic i.e. kinematic sensing and autonomous mapping by means of robotics. Further advances in close-range sensing arise by enhancement of field and reference data collection procedures, integration of measurements from ancillary sources such as geo-sensor networks and cooperative sensor systems, and bridging the gap between ground control measurements and airborne and satellite remote sensing. The increasing availability of mobile and portable close-range sensors lead to the phenomenon of crowd-sensing. Recent achievements on algorithms for automation of data capture and processing stimulate new research questions in the field of geo-environmental research.

Close-range sensing helps for better understanding of geo-environmental processes, their triggers, spatial extent and dynamics over time. Submissions regarding the following topics are welcome: geosphere and biosphere research, integrating close-range sensing with processes in the cryosphere, geomorphology, vegetation phenology, vegetation-geomorphology interaction, and biodiversity.
