Utilização de parâmetros geomorfométricos para a classificação do relevo do município de Mata – RS

Abstract

In recent years, the study of landforms has been increasingly central to the understanding of the geographical space configuration. The relief parameter refers to the quantitative representation of morphologic characteristics described landscapes continuously by equations applied to numerical models of altimetric representation arising geomorphometric attributes. Therefore, a partitioning of relief in the municipality of Mata was conducted through the use of geomorphometric parameters. The classification of the relief of the study area, was held from the proposed automated geomorfométrico mapping Silveira and Silveira (2013), following the precepts of Iwahashi and Pike (2007). The relief of the municipality was also analyzed following the proposal described by Guadagnin and Trentin (2014) and Trentin, Robaina and Silveira (2015), based on a cross topographic indices generated through a georeferenced environment of a GIS and prioritized through a tree decision with pre-defined values. Based on this, the classification of the relief was made by crossing information and topographic attributes extracted from SRTM data generated by a GIS and prioritized through a decision tree, resulting in twelve geomorphometric units for the municipality of Mata
