Methodological proposal for the topographic use of UAV compared to the use oftraditional methods

A methodology for topographic surveys using a UAV is presented, conducted at the Tecnológico de Estudios Superiores de Valle de Bravo (TESVB) with a DJI Phantom 4 Pro RTK drone, DJI GNSS DRTK2 mobile station, and Agisoft Metashape software. The objective is to propose an effective and precise methodology compared to traditional methods. The simplified approach allows for accurate position and processing information, generating digital terrain models. The results offer an efficient alternative, reducing time by 46.66% with a relative error of 0.64% in linear measurements and 0.42% in area measurements. Additionally, the UAV's ability to access various areas and capture real-time data is a significant advantage. This study demonstrates the potential of UAVs in topographic applications, although further analysis in different environments is necessary to fully validate their applicability and accuracy.
