Determinación de coberturas y vegetales a partir del estudio de su respuesta RGB utilizando aerofotografías digitales

Abstract

The identification and registration of vegetation coverage by association performed with conventional methods requires large investments of both time and money. Therefore, the object of this study is to facilitate the identification of VC with the support of a remote sensing process based on aerial digital photography due to the agility, efficiency, and low cost involved in using this technique. In order to determine vegetation coverage using remote sensing based on aerial digital photography, the spectral irradiance emitted by each type of vegetation association was analyzed using aerial digital photography as the source of information. The aerial digital photography were submitted to digital processing techniques that allow for the identification of the different geomorphologic traits in the area that was studied as well as the classification and cataloging of the vegetation coverage using texture recognition algorithms based on the analysis of their spectral signature. Finally, the results that were obtained by the processing of the aerial digital photography in order to determine vegetation coverage were compared to in situ data in order to validate the precision of this method of analysis
