Impervious surface extraction based on different methods from multiple spatial resolution images: a comprehensive comparison

open access: yesInternational Journal of Digital Earth, 2021
Many efforts have been devoted to extracting impervious surfaces based on different methods from multiple spatial resolution images. Differences in extraction methods and spatial resolutions are significant and have led to discrepant performances in ...

Scaling Laws in Spatial Network Formation [PDF]

open access: yesPhysical Review Letters, 2016
Geometric constraints impact the formation of a broad range of spatial networks, from amino acid chains folding to proteins structures to rearranging particle aggregates. How the network of interactions dynamically self-organizes in such systems is far from fully understood. Here, we analyze a class of spatial network formation processes by introducing

The Question of Scale in Integrated Natural Resource Management

open access: yesEcology and Society, 2002
Lessons from integrated natural resource management (INRM) practiced at different scales are reviewed, with a focus on catchment management. INRM is complex, and many interactions have to be addressed.

Selecting a Scale for Spatial Confounding Adjustment

open access: yesJournal of the Royal Statistical Society Series A: Statistics in Society, 2020
SummaryUnmeasured, spatially structured factors can confound associations between spatial environmental exposures and health outcomes. Adding flexible splines to a regression model is a simple approach for spatial confounding adjustment, but the spline degrees of freedom do not provide an easily interpretable spatial scale.

Advances and visions in large-scale hydrological modelling : findings from the 11th Workshop on Large-Scale Hydrological Modelling [PDF]

open access: yes, 2008
Large-scale hydrological modelling has become increasingly wide-spread during the last decade. An annual workshop series on large-scale hydrological modelling has provided, since 1997, a forum to the German-speaking community for discussing recent ...

Reproductive performance links to fine-scale spatial patterns of female grey seal relatedness [PDF]

open access: yes, 2001
Fine–scale spatial patterns of female relatedness throughout the established grey seal breeding colony of North Rona, Scotland, were investigated by accurate mapping and spatially explicit analyses of a large sample (n=262) of mothers using variation at ...

Abundance of mycophagous arthropods present on different species of fungi in relation to resource abundance at different spatial scales

open access: yesEuropean Journal of Entomology, 2005
The abundance of Coleoptera, Diptera and Collembola on different species of fungi was investigated in relation to the size and abundance of fungal resources at different spatial scales; i.e., the size of the fungal fruiting body, the quality of resource ...

Calibration and Validation of the Cosmic Ray Neutron Rover for Soil Water Mapping within Two South African Land Classes

open access: yesHydrology, 2019
Knowledge of soil water at a range of spatial scales would further our understanding of the dynamic variable and its influence on numerous hydrological applications. Cosmic ray neutron technology currently consists of the Cosmic Ray Neutron Sensor (CRNS)
