Abstract

[fre] La gestion rationnelle des ressources naturelles, qui devient chaque jour une nécessité plus grande, suppose une meilleure connaissance, et si possible des mesures précises, des ressources naturelles utilisées, utilisables, dégradées ou en voie de disparition. La télédétection multispectrale par satellite permet d'obtenir des informations numérisées, régulières, et relativement fines sur tous les phénomènes liés à l'occupation et à l'utilisation du sol. A ce titre elle est de plus en plus utilisée comme moyen d'inventaire des ressources naturelles : eaux, forêts, terres agricoles, carrières et gravières, pressions humaines sur les milieux, font l'objet d'observations précises et régulières. Grâce à l'interprétation des images et au traitement des données multispectrales satellite, on peut surveiller les forêts, prévoir les récoltes, gérer les ressources en eau, évaluer les potentialités d'une région naturelle. Le développement rapide des matériels utilisés et des technologies d'application laisse prévoir des progrès considérables dans ce domaine, qui permettront à l'avenir des inventaires plus précis et plus réguliers à des coûts de plus en plus faibles. [eng] Inventories of natural resources by satelite teledetection - The rational management of natural resources which daily becomes of greater urgency supposes a better knowlegde and, fi possible accurate measurements of the natural resources that have been used, are available, have been spoilt or are already disappearing. Multispectral télédétection by satelite enables numerical, regular and relatively detailed information to be obtained concerning all phenomena connected with the occupation and use of land. For this reason it is increasingly used as a means of inventory for natural resources — water, woodland, farm-land, quarries and gravel pits and human pressure inflicted on the environment are regularly and accurately observed. By means of the interpretation of the images and of multispectral satelite data woodland can be observed and protected, harvests can be forecast, water resources can be managed, and the potential of a natural region can be estimated. The rapid development of the material used and of applied technology means that considerable progress can be foreseen in this field which in the future will enable more accurate and more regular forecasts to be made at increasingly smaller expense.
