A Multi-Stage Approach Combining Very High-Resolution Satellite Image, GIS Database and Post-Classification Modification Rules for Habitat Mapping in Hong Kong

Remote Sensing, 2021
Identification and mapping of various habitats with sufficient spatial details are essential to support environmental planning and management. Considering the complexity of diverse habitat types in a heterogeneous landscape, a context-dependent mapping ...

Workflow for the Generation of Expert-Derived Training and Validation Data: A View to Global Scale Habitat Mapping

Frontiers in Marine Science, 2021
Our ability to completely and repeatedly map natural environments at a global scale have increased significantly over the past decade. These advances are from delivery of a range of on-line global satellite image archives and global-scale processing ...

Comparing conservation value maps and mapping methods in a rural landscape in southern Finland

Landscape Online, 2015
We tested to what extent conservation value maps are different if the valuation and mapping method is changed. We compared 66 different conservation value and 4 different ecosystem service maps.

Rhodolith Beds Heterogeneity along the Apulian Continental Shelf (Mediterranean Sea)

Journal of Marine Science and Engineering, 2020
Rhodolith beds represent a key habitat worldwide, from tropical to polar ecosystems. Despite this habitat is considered a hotspot of biodiversity, providing a suite of ecosystem goods and services, still scarce quantitative information is available thus ...

Intuitively visualizing spatial data from biogeographic assessments: A 3-dimensional case study on remotely sensing historic shipwrecks and associated marine life

Frontiers in Climate, 2022
Biogeographic assessments aim to determine spatial and temporal distributions of organisms and habitats to help inform resource management decisions. In marine systems, rapid technological advances in sensors employed for biogeographic assessments allow ...

Mapping for coral reef conservation: comparing the value of participatory and remote sensing approaches

Ecosphere, 2016
Detailed habitat maps are critical for conservation planning, yet for many coastal habitats only coarse‐resolution maps are available. As the logistic and technological constraints of habitat mapping become increasingly tractable, habitat map comparisons
