Foredune Texture: Landscape Metrics and Climate
Annals of the Association of American Geographers, 2014Coastal dunes are sensitive ecosystems because of their location at the juncture of terrestrial, marine, and atmospheric environments. This is especially the case for foredunes and the vegetation they support. Considerable attention is paid to the characteristics of foredunes and dune vegetation, but there has been no systematic study of patterns of ...

Measuring landscape configuration with normalized metrics
Landscape Ecology, 2011Natural and anthropogenic disturbances on natural landscapes reduce the abundance and alter the spatial arrangement of certain habitat types. Measuring and modeling such alterations, and their biological effects, remains challenging in part because many widely used configuration metrics are correlated with habitat amount. In this paper, we consider the

Landscape Pattern Metrics and Regional Assessment
Ecosystem Health, 1999ABSTRACT The combination of remote imagery data, geographic information systems software, and landscape ecology theory provides a unique basis for monitoring and assessing large‐scale ecological systems. The unique feature of the work has been the need to develop and interpret quantitative measures of spatial pattern—the landscape indices. This article

Patterns of Correlation Among Landscape Metrics
Physical Geography, 2007Representations of real and virtual landscapes are often abstracted and quantified as "landscape metrics" in landscape ecology, and while much is known about them after 20 years of use, some relations are as yet unexplored. The objective of this research is to gain a better understanding of the effects of spatial representation in landscape ecology ...

Ecological epidemiology: landscape metrics and human alveolar echinococossis
Acta Tropica, 2004The larval form of the fox tapeworm Echinococcus multilocularis can cause a potentially fatal liver infection in human hosts. Globally rare, the disease has a high prevalence focus in western China. Recent research has linked landscape to the presence and prevalence of the disease. This paper discusses the epidemiology of E.

Software Metrics Suites for Project Landscapes
2009 13th European Conference on Software Maintenance and Reengineering, 2009Many software metrics have been proposed over the past decades. Selecting a small custom suite of metrics is desirable for quality assessment and defect prediction in industrial practice since developers cannot easily cope with dozens of metrics. In large software architectures, structurally similar projects are subject to similar defect conditions and

Applying landscape ecological concepts and metrics in sustainable landscape planning
Landscape and Urban Planning, 2002It is increasingly recognized that more sustainable approaches are needed for planning and managing landscapes worldwide. New tools are needed to effectively apply sustainable principles to planning and management. The spatial dimension of sustainability engages processes and relations between different land uses, ecosystems and biotopes at different ...

Resolution problems in calculating landscape metrics
Journal of Spatial Science, 2005The variation of landscape metrics caused by varying the map input resolution has been investigated. Landscape metrics are spatial indicators used to link spatial patterns with the ecological processes that generate them. An aerial photograph was semi‐automatically classified at different resolutions by superimposing a grid with a variable cell ...

The adequacy of different landscape metrics for various landscape patterns
Pattern Recognition, 2005The behavior of several landscape pattern metrics were tested against various pattern scenarios generated by neutral landscape models, including number of classes, scale-map extent, scale-resolution, class proportion, aggregation level-RULE, and aggregation level-SimMap.
