Exploration in Mapping Kernel-Based Home Range Models from Remote Sensing Imagery with Conditional Adversarial Networks

Remote Sensing, 2018
Kernel-based home range models are widely-used to estimate animal habitats and develop conservation strategies. They provide a probabilistic measure of animal space use instead of assuming the uniform utilization within an outside boundary. However, this

Spectral features of dual-frequency multibeam echosounder data for benthic habitat mapping

, 2020
Automatic methods of seafloor mapping are still in their early stage of development, despite the technical progress made in recent years. A serious imperfection is the limited types of predictor features available for seabed classification.

Detection of Boulders in Side Scan Sonar Mosaics by a Neural Network

Geosciences, 2019
Boulders provide ecologically important hard grounds in shelf seas, and form protected habitats under the European Habitats Directive. Boulders on the seafloor can usually be recognized in backscatter mosaics due to a characteristic pattern of high ...

Seasonal change of multifrequency backscatter in three Baltic Sea habitats

Frontiers in Remote Sensing, 2022
This study investigated the seasonality of acoustic backscatter intensities, exploring three habitats in the southwestern Baltic Sea: 1) a mussel-covered reef, 2) coarse sand and gravel, and 3) seagrass meadows.

Using incomplete floristic monitoring data from habitat mapping programmes to detect species trends

Diversity and Distributions: A journal of biological invasions and biodiversity, 2020
The loss of biodiversity has raised serious concerns about the entailing losses of ecosystem services. Here, we explore the potential of repeated habitat mapping data to identify floristic changes over time. Using one German federal state as a case study,
