Landscape Habitat Suitability Index Software
The Journal of Wildlife Management, 2007ABSTRACT Habitat suitability index (HSI) models are traditionally used to evaluate habitat quality for wildlife at a local scale. Rarely have such models incorporated spatial relationships of habitat components.

Landscape Criticality Indexes for the Different Pollutants
2005The effect of the landscape indication permits a reliable inter-component cross-identification within the landscape. Thus, the landscape approach to the evaluation the criticality indexes can be used for the radioecological evaluations, even if the environmental characteristics of the territory affected are limited or non-reliable.

Structure−Activity Landscape Index: Identifying and Quantifying Activity Cliffs
Journal of Chemical Information and Modeling, 2008A new method for analyzing a structure-activity relationship is proposed. By use of a simple quantitative index, one can readily identify "structure-activity cliffs": pairs of molecules which are most similar but have the largest change in activity. We show how this provides a graphical representation of the entire SAR, in a way that allows the salient

Construction of landscape ecological evaluation index system
2011 International Symposium on Water Resource and Environmental Protection, 2011As urban construction development, urban landscape ecological environment is drawing wide attention. Therefore, it is important to build urban landscape ecological evaluation system adapt to city development. This paper comprehensively studied major problems in urban landscape construction.

Soil Landscapes, an Index to Multiple use
Journal of Forestry, 1966Abstract In order to develop good multiple-use plans for any area, it is necessary to know the potential of the land for various uses. This paper presents how soil landscapes may serve as a starting point or as an index to multiple-use planning. Examples are presented at the project or compartmental level and for a ranger district on

Landscape cohesion: an index for the conservation potential of landscapes for biodiversity
2003In urbanising landscapes, planning for sustainable biodiversity occurs in a context of multifunctional land use. Important conditions for species persistence are habitat quality, the amount and configuration of habitat and the permeability of the landscape matrix. For planning purposes, these determinants should be integrated into simple indicators for

Estimating Landscape Imperviousness Index From Satellite Imagery
IEEE Geoscience and Remote Sensing Letters, 2006This letter presents a practical method for landscape imperviousness estimation through the synergistic use of Landsat Enhanced Thematic Mapper Plus (ETM+) and high-resolution imagery. A 1-m resolution color-infrared digital orthophoto was used to calibrate a stepwise multivariate statistical model for continuous landscape imperviousness estimation ...

The Satoyama Index: A biodiversity indicator for agricultural landscapes
Agriculture, Ecosystems & Environment, 2011Abstract Agricultural development to meet rapidly growing demands for food and biofuel and the abandonment of traditional land use have had major impacts on biodiversity. Habitat diversity is one of the most important factors influencing biodiversity in agricultural landscapes.

Application of the topographic position index to heterogeneous landscapes
Geomorphology, 2013Topographic position index (TPI) is an algorithm increasingly used to measure topographic slope positions and to automate landform classifications. We applied TPI to a geoarchaeological research project in northwestern Belgium but its use led to erroneous landform classifications in this heterogeneous landscape.
