Landscape connectivity is integral to the persistence of metapopulations of wide ranging carnivores and other terrestrial species. The objectives of this research were to investigate the landscape characteristics essential to use of areas by lynx and bobcats in northern New England, map a habitat availability model for each species, and explore connectivity across areas of the region likely to ...

Understanding how nitrogen transport across the landscape varies with landscape characteristics is important for developing sound nitrogen management policies. We used a spatially referenced regression analysis (SPARROW) to examine landscape characteristics influencing delivery of nitrogen from sources in a watershed to stream channels. Modelled landscape delivery ratio varies widely (by a fact...

The Landscape Genetics GIS Toolbox contains tools that run in the Geographic Information System software, ArcGIS(®), to map genetic landscapes and to summarize multiple genetic landscapes as average and variance surfaces. These tools can be used to visualize the distribution of genetic diversity across geographic space and to study associations between patterns of genetic diversity and geograph...

The study figures out the potential of CASI airborne hyperspectral imagery for the fine segmentation and characterization of small size landscape units, the hedges, essential for hydrologists and landscape planners. The segmentation strategy consists in computing every hedge discriminating feature : radiometry, texture and linear shape. Original methods taking into consideration the full spectr...

We investigate an integrated approach to scientometric studies with emphasis to the use of information visualization and animation techniques. This study draws upon citation and co-citation patterns derived from articles published in the journal Scientometrics (19812001). The modeling and visualization takes an evolutionary and historical perspective. The design of the visualization model adapt...

Geospatial data form the foundation of an information-based society. Cell-based raster data are well suited to represent geographic phenomena and help model landcover and landuse characteristics and relevant attributes. Information technologies capable of credible raster map analysis and change detection are needed for integrated regional assessment and development in the 21st Century equipped ...

An energy landscape map (ELM) characterizes and visualizes an energy function with a tree structure, in which each leaf node represents a local minimum and each non-leaf node represents the barrier between adjacent energy basins. We demonstrate the utility of ELMs in analyzing non-convex energy minimization problems with two case studies: clustering with Gaussian mixture models and learning mix...

The Landscape Genetics GIS Toolbox contains tools that run in the Geographic Information System software, ArcGIS , to map genetic landscapes and to summarize multiple genetic landscapes as average and variance surfaces. These tools can be used to visualize the distribution of genetic diversity across geographic space and to study associations between patterns of genetic diversity and geographic...
