Pedoforms mapping at the Águas Emendadas ecological station, Distrito Federal, Brazil.

The great urban and rural development of the Distrito Federal (Federal Administrative District) in Brazil over the last 50 years has led to disordered land use and land occupation. To assess the current environmental scenario, detailed surveys of the available natural resources, especially soils, are required. The objective of this work was to evaluate the soils-landscape relations in a representative area of the region, the Águas Emendadas Ecological Station, and map its soil forms (pedoforms) using geotechnologies. The geographical distribution of the soils in the regional landscape was modelled according to the geological, geomorphological and pedological relations observed in the field. Based on this model, the available geological and eomorphological maps of the Distrito Federal, along with the Digital Terrain Model (DTM) and slope classification map produced in this work, were used to map the pedoforms. For the scale used in this work, the resulting pedoforms map was considered adequate and can subsidize detailed soil studies and environmental planning.
