The emergence of increasingly accurate, fast, and inexpensive tools in the acquisition of data for the management base suitable for each type of environment is fundamental in the development of sustainable engineering. Based on this, the evaluation of the accuracy of the volume calculation performed using Digital Terrain Models (DTM’s), generated by images of Unmanned Aerial Vehicle (UAV) was carried out. The study was conducted in the area of the new landfill in the municipality of Fortaleza, state of Ceará, in a waste stabilization pond. Two DTM’s were generated and evaluated. The first was generated by collecting points from a Global Navigation Satellite System (GNSS) receiver, using 445 points, whereas the second was generated by aerial images obtained through a multirotor UAV, with 17 checkpoints and 10 Ground Control Points (GCP’s). With the two DTM’s of the GNSS Receiver and the UAV, the volume of the stabilization pond was calculated using the TopoEVN and Pix4D software, respectively. The estimated pond volume obtained through the Global Positioning System (GPS) data was 48548,33 m³, while by the UAV DTM, it was 48504,9 m³. The accuracy of the volume data obtained by DTM generated by UAV, even with considerable flight height (120 m), presented a result with variation less than 1% compared to those arising from conventional topography, thus indicating high reliability and data accuracy.

“…Unmanned aerial vehicles (UAVs), also known as drones, are being increasingly employed in various demands and applications (Rodrigues et al, 2018), such as in environmental monitoring (Young et al, 2021) and precision agriculture (Klauser & Pauschinger, 2021;Tsouros et al, 2020), as well as in different types of mapping, i.e., topographical (Quispe Enriquez, 2015) or soil (Wu et al, 2019), geological (Vasuki et al, 2014;Dandar et al, 2018) or geomorphological-themed (Papakonstantinou et al, 2016), among others.…”

Unmanned aerial vehicles (UAVs), also known as drones, are being increasingly applied in different demands and applications, mainly in mapping. Despite the agility and practicality provided by this technology, the image processing software programs currently available on the market are costly and cannot meet teaching/research demands, especially in Brazilian public universities. In this context, this study aimed to evaluate the positional accuracy of products resulting from the digital processing of UAV images using commercial software (Agisoft Metashape) and open-source software (Opendronemap). The planimetric accuracy of the orthophoto mosaic resulting from the two software was not acceptable according to the tolerances defined in the standardization document for planimetric and altimetric accuracy for digital geospatial data, established by the ASPRS (American Society for Photogrammetry and Remote Sensing). Only the altimetric accuracy corresponding to the DEM produced by Opendronemap was satisfactory.

O Cadastro Técnico Multifinalitário (CTM) tem como base o cadastro imobiliário que pode ser realizado com levantamentos topográficos e, quando bem implantado no município, é uma ferramenta eficiente de gestão pública e planejamento urbano. O presente trabalho busca apresentar um estudo onde são comparados diferentes equipamentos e métodos de levantamento topográficos aplicáveis na implantação, manutenção e atualização de base cadastral municipal aplicado à municípios de pequeno e médio porte. Além disso, o estudo compara e discute alguns procedimentos e cuidados que devem ser observados na realização de levantamentos topográficos utilizando trena de fibra de vidro, trena a laser, estação total, receptores GNSS e Veículo Aéreo não Tripulado (VANT). São analisados os diferentes tipos de levantamento estudoe é apresentado os principais pontos positivos e negativos de cada método. Por fim o, trabalho apresenta e discute os principais resultados e compara os demais métodos de levantamento com o VANT. Os resultados indicam que os métodos estudados são métodos complementares e sua utilização são compatíveis para a implantação e manutenção do CTM. Também é evidenciado o elevado potencial do uso de VANT em atualização cadastral municipal de pequenas áreas isoladas. No desenvolvimento dos trabalhos foi possível identificar divergências no Boletim de Cadastro Imobiliário (BCI)da área objeto de estudo.
