Abstract

The development of new techniques that facilitate environmental planning are needed, so this work presents a new methodological approach : the Model of Stability of Soil Science (MES) , which uses data obtained by remote sensing in order to support environmental planning . The technique was applied in the city of Costa Rica - MS with Landsat generating an environmental zoning proposal for the study area. The letter slope was drawn through the SRTM digital elevation model. The Charter Fitness of Lands (agricultural capability of the soil) was obtained from the Multi Referral Atlas of the State of Mato Grosso do Sul linear spectral mixture model to derive vegetation fraction image ( letter of vegetation cover ) was used . With this data set we applied the MES through map algebra, which uses the overlay of information layers slope, agricultural soil suitability and land cover. Data obtained via MES were compared with those observed in the field. Thus it can be seen that the MES was efficient in assessing the areas most vulnerable to the erosive action, moreover, proved to be an efficient tool for decision making.
