Statewide land-cover change detection analysis provides a useful tool for conservation planning and environmental monitoring and addresses issues of habitat fragmentation and urban sprawl. Furthermore, land-cover data offer a historical and recent perspective on landscape dynamics. To this end, the first alliance level land-cover map of Kansas (Kansas Vegetation Map) recently completed by the K...

metric (mapping evapotranspiration at high resolution with internalized calibration) is known as an appropriate surface energy balance model for the estimation of the spatial distribution of evapotranspiration (et) in semi-arid regions. based on lysimeter measurements, metric has shown et estimates of 10% on a sub-field scale on a daily basis. there is a need to identify how the model is sensit...

The objective of this study was to document the current state of health insurance cover for reproductive immunology in the USA. A survey of couples who had given birth to a child within the last 2 years while they were being treated with lymphocyte immunotherapy at the Reproductive Medicine Clinic of the Finch University of Health Sciences/The Chicago Medical School (FUHS/CMS), North Chicago, I...

En este trabajo se presenta un análisis morfológico de cobertura forestal en un lapso de doce años. Se emplearon dos imágenes multiespectrales LANDSAT TM-4 de los años 1989 y 2001. Estas imágenes cubren un área forestal donde han ocurrido cambios significativos en tales años. Estas imágenes fueron expandidas en términos de variables canónicas que describen la respuesta espacialespectral de las ...

Fuzzy Image Regions were proposed recently as an alternative GEOBIA method for conducting qualitative land cover classification. In this paper, these fuzzy segments are applied for estimation of quantitative (i.e. compositional) land cover. The method comprises three main stages: (i) fuzzy segmentation to create segments with indeterminate boundaries and uncertain thematic allocation; (ii) feat...

V ∋vpF (V ). We assume that the qF ’s are given but pF ’s are not. Repeated evaluations of a filter yields the same state: in particular, evaluations of a filter F by two distinct algorithms yields the same V (F ). We assume filters are independent: conditioning on the complete or partial state of filters other than F does not alter the state distribution of F . Let C(F ) denote the cost of eva...

A methodology was developed to interpret and assess land cover change between 1991 and 1999 in Central Puget Sound, Washington at several scales (landscape, sub-basins, and 90 m grid window) relevant to regional and local decision makers. Land cover data are derived from USGS Landsat (Thematic Mapper and Enhanced Thematic Mapper ) images of Central Puget Sound. Landsat data were registered, int...

Changes in land-use systems in tropical regions, including deforestation, are a key challenge for global sustainability because of their huge impacts on green-house gas emissions, local climate and biodiversity. However, the dynamics of land-use and land-cover change in regions of 5 frontier expansion such as the Brazilian Amazon is not yet well understood because of the complex interplay of ec...

Time sequential Landsat MSS and TM images were used to map land use/cover of the Atlanta metropolitan area for the past 25 years as a component of the NASA-funded Project ATLANTA (ATlanta Land-use ANalysis: Temperature and Air-quality), which has the objective to model the impact of land use/cover change on temperature and air quality in Atlanta. This paper describes a suite of techniques that ...
