Habitat Mapping and Change Assessment of Coastal Environments: An Examination of WorldView-2, QuickBird, and IKONOS Satellite Imagery and Airborne LiDAR for Mapping Barrier Island Habitats

open access: yesISPRS International Journal of Geo-Information, 2014
Habitat mapping can be accomplished using many techniques and types of data. There are pros and cons for each technique and dataset, therefore, the goal of this project was to investigate the capabilities of new satellite sensor technology and to assess ...

An operational land cover and land cover change toolbox: processing open‐source data with open‐source software

open access: yesEcological Solutions and Evidence, 2022
Accurate and up‐to‐date land cover maps are vital for underpinning evidence‐based landscape management decision‐making. However, the technical skills required to extract tailored information about land cover dynamics from these open‐access geospatial ...

Extending regional habitat classification systems to ocean basin scale using predicted species distributions as proxies

open access: yesFrontiers in Marine Science, 2023
The patchy nature and overall scarcity of available scientific data poses a challenge to holistic ecosystem-based management that considers the whole range of ecological, social, and economic aspects that affect ecosystem health and productivity in the ...

Classification of Seafloor Habitats Using Genetic Programming [PDF]

open access: yes, 2008
In this paper we use Genetic Programming for the classification of different seafloor habitats, based on the acoustic backscatter data from an echo sounder. By dividing the multiple-class problem into several two-class problems, we were able to produce nearly perfect results, providing total discrimination between most of the seafloor types used in ...

Classification hiérarchique des zones boisées d’altitudes de l’île d’Anjouan, Comores

open access: yesVertigO, 2020
The second largest island of the Comoros archipelago, Anjouan, was covered by forest before human colonization, whereas today only a few forest fragments remain on steep and inaccessible slopes. Under human pressure, the loss of forests to make place for

Planktonic habitats in the Amazon Plume region of the Western Tropical North Atlantic

open access: yesFrontiers in Marine Science
The Western Tropical North Atlantic is a highly dynamic marine system where the Amazon River Plume (ARP) generates a patchwork of environmental conditions that favor different phytoplankton groups.

Habitat classification of East-European tundra

open access: yesTransaction Kola Science Centre, 2021
The small contour and mosaic of tundra landscapes leads to the predominance of complex territorial units of vegetation (complexes, serial and ecological series, combinations). For accurate diagnostics and mapping of habitat categories in the tundra zone, we have developed a typological scheme based on the types of combinations of territorial units of ...

Polychaete distribution pattern on the Valencian Community coast, Spanish Mediterranean

open access: yesCiencias Marinas, 2011
Changes in benthic community structure are strongly related to environmental factors, and we need to determine how these natural changes occur in order to interpret the possible changes associated with anthropogenic impacts.
