Evaluating the effectiveness of landscape configuration metrics from landscape composition metrics

Landscape and Ecological Engineering, 2016
Although landscape configuration and landscape composition metrics are correlated theoretically and empirically, the effectiveness of configuration metrics from composition metrics has not been explicitly investigated. This study explored to what extent substantial information of configuration metrics increases from certain easily calculated and ...

Landscape Metrics for Assessment of Landscape Destruction and Rehabilitation

Environmental Management, 2001
This investigation tested the usefulness of geometry-based landscape metrics for monitoring landscapes in a heavily disturbed environment. Research was carried out in a 75 sq km study area in Saxony, eastern Germany, where the landscape has been affected by surface mining and agricultural intensification.

Landscape Metrics and Visual Topology in the Analysis of Landscape Preference [PDF]

Environment and Planning B: Planning and Design, 2008
Recognition of the value of landscapes, environmentally, economically, and to quality of life—and, importantly, the embedding of these concepts in legislation such as the European Landscape Convention—has led to the need for an ‘objective’ assessment of these values and the potential impact of changes to them.

Understanding Landscape Metrics II

2006
An extensive set of landscape metrics exists to quantify spatial patterns in heterogeneous landscapes. Developers and users of these metrics typically seek to objectively describe landscapes that humans assess subjectively as, for example, “clumpy,” “dispersed,” “random,” “diverse,” “fragmented,” or “connected.” Because the quantification of pattern is

Seeking parsimony in landscape metrics

The Journal of Wildlife Management, 2011
AbstractNumerous metrics describing landscape patterns have been used to explain landscape‐scale habitat selection by birds. The myriad metrics, their complexity, and inconsistent responses to them by birds have led to a lack of clear recommendations for managing land for desired species.

Foredune Texture: Landscape Metrics and Climate

Annals of the Association of American Geographers, 2014
Coastal 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, 2011
Natural 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, 1999
ABSTRACT 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, 2007
Representations 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 ...
