Base mapping is an obvious, but often neglected, function of remote sensing. Therefore, this paper begins by examining the rôle remote sensing has to play in this area. Particular attention is paid to the increasing availability and use of fine
spatial resolution satellite sensor imagery and the data requirements of geographical information systems (GIS). This is followed by a broader discussion on the various mapping applications of remote sensing and, finally, a brief summary of general
The goal of this paper is to review remote sensing studies applied in arctic environments to estimate vegetation community structure and biophysical properties. Tundra spectral characteristics and biomass estimation using vegetation indices
The semi-empirical water cloud model can be implemented to derive spatial values of biophysical parameters from remotely sensed radar data for use throughout different disciplines of physical geography. The water cloud model formulation

In this study SEBAL, an evapotranspiration (ET) computation model using remote sensing method is applied in the Yellow River Delta where water resource faces a rigorous situation. Three Landsat TM images and meteorology data of 1999 were used for ET
and monitor eelgrass using satellite remote sensing. The test, using Landsat TM data from 2 dates (1989 and 2000), clearly indicates the potential of the technique, but further studies are needed before it is fully operational.

The method for simulating the temporal and spatial distribution patterns of leaf area index (LAI) and biomass at landscape scale using remote sensing images and surface data is discussed in this paper. The method is based on Landsat Thematic Mapper
The article focuses on detection of landcover quality changes from remote sensed data in the core zone of the extreme flood in August 2002. Mainly are described changes of temperature - humidity parameters through the comparison of the multispectral
Le Plan Bleu a initié un séminaire de travail de deux jours regroupant une vingtaine d'experts originaires de chacun de pays riverains de la Méditerranée. Trois objectifs : 1. Comprendre le sens et l'intensité des évolutions actuelles concernant les
milieux montagnards méditerranéens. 2. Identifier les enjeux de ces évolutions dans les vingt années à venir en s'inscrivant dans une démarche de développement durable. 3. Formuler quelques recommandations à privilégier pour infléchir l'avenir dans le sens
