Se evaluaron dos tipos de software, cuatro opciones de procesamiento y cuatro parámetros de vuelo para obtener ortomosaicos en plantaciones forestales ubicadas en Costa Rica. Se encontró que el software Pix4Dmapper® requiere menos tiempo para el procesamiento de imágenes, especialmente cuando el computador utilizado tiene al menos 15 GB de memoria RAM. El número de imágenes a procesar por hectárea se puede disminuir reduciendo la resolución espacial de las imágenes y usando un trazado de vuelo (2D). El software WebODM® produjo más fallos en el procesamiento, pero los ortomosaicos generados tuvieron menos áreas con omisiones que los generados con Pix4Dmapper®. La proporción de fallos en el procesamiento está relacionada con la cantidad de imágenes a procesar y la resolución espacial de las mismas. Las mejores combinaciones para obtener ortomosaicos se obtuvieron usando Pix4Dmapper® con vuelos a 120 metros, empleando un ángulo de cámara de 90° y una combinación de traslape entre imágenes de 80 % frontal y 70 % lateral.]]></p></abstract>

Two softwares, four processing tools options and four flight parameters were evaluated to obtain orthomosaics in forest plantations located in Costa Rica. It was found that Pix4Dmapper® software requires less time for image processing, especially when using computers with at least 15 GB of RAM. The number of images to process per hectare can be lowered by reducing the spatial resolution of the images and using a flight plot (2D). The WebODM® software produced more processing failures, but the generated orthomosaics had fewer omission areas than those generated with Pix4Dmapper®. The proportion of processing failures is related to the number of images to be processed and the spatial resolution of the images. The best combinations to obtain orthomosaics were achieved using Pix4Dmapper® with flights at 120 meters, using a camera angle of 90° and a combination of overlap between images of 80 % frontal and 70 % lateral.]]></p></abstract>
