We participated in the first annual meeting of Drones Fotogrametría Pro, held at Tecnológico de Monterrey. The event gathered students, researchers, companies and representatives of government institutions, as well as the people involved or interested in the use of drones for geophysical studies.
In this first edition we had the honor to participate as speakers presenting a comparison between digital elevation models performed with drones and RTK precision topography. The presentation was led by Pedro Olivares Sainz, Executive Director and Andrés Arzáte, Director of the Geophysics and Exploration area in AV3 AEROVISUAL.
The topography, as well as the digital models, are a great tool, essential for any kind of scientific exploration or constructive action; for this reason different techniques have emerged to generate representations of the surfaces and their respective models. These techniques usually consist of taking points spatially equidistant from each other, with specialized equipment that has mirror and laser systems which are expensive and robust. In this project, presented during the meeting in Jalisco, compares the generation of models with drones using photogrammetry with differential topography carried out in the center of the city of Queretaro Mexico, which is a very active place, and topographically very uneven due to the great amount of alleys, passages and complex structures such as churches and fountains. Several elements of these techniques were compared to show the benefits of this method against this well-known technique.
