The acquisition, processing and analysis of terrain or infrastructure data obtained from aerial photographs have revolutionized the world of photogrammetry and photo interpretation. Currently, various equipment such as remotely piloted aircraft (RPAS) and different software capable of processing and generating models have been developed. In this research, the processing of digital images obtained through RPAS aerial vehicles in the permanent monitoring plot of the Chicaque Natural Park was carried out with the help of the RGB and the MicaSense Altum multispectral camera. With this information, a 2D orthomosaic and 3D model of the area was created, the respective multispectral analysis of the vegetation was carried out, the topographic profiles of the plot were obtained and the height of the trees was approximated. These models were made in 3Dsurvey and Pix4Dmapper programs.
