Investigación y desarrollo de mapeo fotogramétrico mediante el uso de vehículo aéreo no tripulado (uav) en Piamonte.

Abstract

The process of collecting spatial data in the area located between San Juan Bosco and Limón Indanza has presented a significant challenge due to its lush vegetation, varied topography and the presence of wild fauna. Thus, data collection has required considerable time and resources for the information to be correct and accurate. Hence, this research aimed to develop the photogrammetric mapping of Piamonte area due to the topographic survey via drone or unmanned aerial vehicle (UAV). A method of application was applied to achieve the proposed objectives; three different phases have been defined; the preliminary one implies literature research about photogrammetry, drone flying practices and the identification of the area; the field research phase based on planned and aerial surveys were conducted, using mobile software for the correct data collection and finally the office work stage, which includes data processing through a photogrammetric information processing software. Applying that methodology, it has been possible to generate a raster digital model after obtaining a data set for the spatial distribution in Piamonte area, where there was no previous topographic data. It is a very extensive area, ideal for topographic information surveys. In addition, level curves which are vitally important to know the relief of the place effectively were obtained. In conclusion, through photogrammetry have been determined many parameters analyzed, such as: land measurements, level curves, digital terrain model and the orthophoto, so it was important to determine the general conditions of the terrain.
