Using floristic gradient mapping to assess seasonal thaw depth in interior Alaska

Döpper, Veronika ; Panda, Santosh ; Waigl, Christine ; Braun, Matthias ; Feilhauer, Hannes (2021-02-22)

Questions Is it possible to map floristic gradients in heterogeneous boreal vegetation by using remote‐sensing data? Does a continuous vegetation map enable the creation of a spatially continuous map of seasonal permafrost soil thaw depth? Location Bonanza Creek LTER, Fairbanks, Alaska, USA. Methods Vegetation records are subjected to an ordination to extract the predominant floristic grad...

Delineation of management zones with spatial data fusion and belief theory

Vallentin, Claudia ; Dobers, Eike Stefan ; Itzerott, Sibylle ; Kleinschmit, Birgit ; Spengler, Daniel (2019-11-22)

Precision agriculture, as part of modern agriculture, thrives on an enormously growing amount of information and data for processing and application. The spatial data used for yield forecasting or the delimitation of management zones are very diverse, often of different quality and in different units to each other. For various reasons, approaches to combining geodata are complex, but necessary ...

Automatic delineation algorithm for site-specific management zones based on satellite remote sensing data

Georgi, Claudia ; Spengler, Daniel ; Itzerott, Sibylle ; Kleinschmit, Birgit (2017-11-15)

In light of the increasing demand for food production, climate change challenges for agriculture, and economic pressure, precision farming is an ever-growing market. The development and distribution of remote sensing applications is also growing. The availability of extensive spatial and temporal data—enhanced by satellite remote sensing and open-source policies—provides an attractive opportuni...

The Regenerative Potential of Managed Calluna Heathlands—Revealing Optical and Structural Traits for Predicting Recovery Dynamics

Neumann, Carsten ; Schindhelm, Anne ; Müller, Jörg ; Weiss, Gabriele ; Liu, Anna ; Itzerott, Sibylle (2021-02-09)

The potential of vegetation recovery through resprouting of plant tissue from buds after the removal of aboveground biomass is a key resilience strategy for populations under abrupt environmental change. Resprouting leads to fast regeneration, particularly after the implementation of mechanical mowing as part of active management for promoting open habitats. We investigated whether recovery dyn...

Remote sensing for precision agriculture

Vallentin, Claudia (2021)

Background: Agriculture is a large and dynamic sector, essential for the supply of the population and thus in a complex area of tension. The growing population and the resulting need for optimization, greater efficiency and intensification are in direct conflict with the demand for sustainability, environmental compatibility and, above all, mitigation of climate change and its consequences. Pre...

Comparing Sentinel-1 and -2 Data and Indices for Agricultural Land Use Monitoring

Holtgrave, Ann-Kathrin ; Röder, Norbert ; Ackermann, Andrea ; Erasmi, Stefan ; Kleinschmit, Birgit (2020-09-09)

Agricultural vegetation development and harvest date monitoring over large areas requires frequent remote sensing observations. In regions with persistent cloud coverage during the vegetation season this is only feasible with active systems, such as SAR, and is limited for optical data. To date, optical remote sensing vegetation indices are more frequently used to monitor agricultural vegetatio...

Evaluation of Remote-Sensing-Based Landslide Inventories for Hazard Assessment in Southern Kyrgyzstan

Golovko, Darya ; Roessner, Sigrid ; Behling, Robert ; Wetzel, Hans-Ulrich ; Kleinschmit, Birgit (2017-09-15)

Large areas in southern Kyrgyzstan are subjected to high and ongoing landslide activity; however, an objective and systematic assessment of landslide susceptibility at a regional level has not yet been conducted. In this paper, we investigate the contribution that remote sensing can provide to facilitate a quantitative landslide hazard assessment at a regional scale under the condition of data ...

Spatio-temporal analysis of landslide hazard in southern Kyrgyzstan Using GIS and remote sensing data

Golovko, Darya (2019)

Large areas in southern Kyrgyzstan are affected by intensive landsliding, which results in the loss of human life and damages to the housing and infrastructure. A quantitative landslide hazard assessment based on a systematic landslide record is needed to better understand landslide processes in the region and to implement more effective hazard mitigation measures. Landslide investigations have...

Monitoring of Calcite precipitation in hardwater lakes with multi-spectral remote sensing archives

Heine, Iris Elisabeth ; Brauer, Achim ; Heim, Birgit ; Itzerott, Sibylle ; Kasprzak, Peter ; Kienel, Ulrike ; Kleinschmit, Birgit (2017)

Calcite precipitation is a common phenomenon in calcium-rich hardwater lakes during spring and summer, but the number and spatial distribution of lakes with calcite precipitation is unknown. This paper presents a remote sensing based method to observe calcite precipitation over large areas, which are an important prerequisite for a systematic monitoring and evaluation of restoration measurement...

Reconstruction of lake level changes of groundwater-fed lakes in Northeastern Germany using RapidEye time series

Heine, Iris Elisabeth ; Stüve, Peter ; Kleinschmit, Birgit ; Itzerott, Sibylle (2015)

Groundwater-fed lakes in northeastern Germany are characterized by significant lake level changes, but for only a few lakes are in situ water level measurements available. In this study, we test the potential of RapidEye satellite images for indirectly reconstructing lake level changes. The lake levels are derived by intersecting water-land borders with a high-resolution digital elevation model...

Potential of remote sensing to predict species invasions: a modelling perspective

Rocchini, Duccio ; Andreo, Veronica ; Förster, Michael ; Garzon-Lopez, Carol Ximena ; Gutierrez, Andrew Paul ; Gillespie, Thomas W. ; Hauffe, Heidi C. ; He, Kate S. ; Kleinschmit, Birgit ; Mairota, Paola ; Marcantonio, Matteo ; Metz, Markus ; Nagendra, Harini ; Pareeth, Sajid ; Ponti, Luigi ; Ricotta, Carlo ; Rizzoli, Annapaola ; Schaab, Gertrud ; Zebisch, Marc ; Zorer, Roberto ; Neteler, Markus (2015)

Understanding the causes and effects of species invasions is a priority in ecology and conservation biology. One of the crucial steps in evaluating the impact of invasive species is to map changes in their actual and potential distribution and relative abundance across a wide region over an appropriate time span. While direct and indirect remote sensing approaches have long been used to assess ...
