Este estudo visa realizar pesquisas na base de dados Scopus e Web of Science sob o intuito de procurar trabalhos relativos ao mapeamento hídrico com o enfoque em áreas de risco utilizando VANTs. O software VOSViewer, gera infográficos fundamentados no sistema de nós exibindo os principais termos da pesquisa, autores, elementos recorrentes e palavras-chave. Categorizando os trabalhos, de forma quantitativa, em autores colaboradores, abordagem referente ao tema, tipos de publicações, principais revistas, índices, principais países, redes de colaboração e palavras-chaves, indicou os principais trabalhos pertinentes ao tema, em que, esses foram discutidos para a verificação de como o tema é abordado. 91,15% dos trabalhos estão escritos em inglês, sendo os EUA o segundo país que mais publica sobre, na retaguarda da China. Os principais termos concatenados a pesquisa são UAV – Unmanned Aerial Vehicles, Photogrammetry e DEM - Digital elevation Model, que fazem alusão ao uso de VANTs para obtenção do MDE e MDS pelo método fotogramétrico. Dentre os trabalhos, 10 apresentaram material metodológico e resultados promissores na utilização de VANT ́para mapeamento de risco hidrológico, com destaque aos trabalhos de Mazzoleni, Muthusamy Annis, Luppichini, que apresentam softwares de processamento de imagem (Agisoft PhotoScan) e de simulações hidrodinâmicas de águas pluviais e fluviais (FLO-2D e HEC-RAS). Logo, esse estudo viabilizou reconhecer condutas metodológicas, tendências, dificuldades e as vantagens da ferramenta VANT, na aplicação técnica, como alta precisão, custo relativamente baixo e alcance em áreas de difícil acesso.

Unmanned Aerial Vehicles (UAVs) are being used for a wide variety of applications including detecting and tracking wildland fires. Using UAVs for fire-fighting purposes reduces the human involvement for this high risk job. Such a mission involves locating the wildland fire, tracking the direction of spread of the fire and searching for human presence in the region. This paper investigates the algorithmic development for the use of UAVs to detect and track wildland fires. This would involve using the fuzzy toolbox in MATLAB along with MICRODEM, a software which provides the Digital Elevation Model (DEM) for the region. The objective of this research is to accomplish the following: 1) use genetic fuzzy based image processing tools to identify fire from the video feed obtained from the camera attached to the UAV in real time 2) look for human presence in the region and 3) estimate the location of the fire based on the geological data available for the region.

Elevation Model

To use unmanned aerial vehicles (UAVs) for obtaining digital elevation models (DEM) and digital terrain models (DTM) is currently actively practiced in scientific and practical purposes. This technology has many advantages: efficiency, ease of use, and the possibility of application on relatively small area. This allows us to perform qualitative and quantitative studies of the progress of dangerous relief-forming processes and to assess their consequences quickly. In this paper, we describe the process of obtaining a digital elevation model (DEM) of the relief of the slope located on the bank of the Protva River (Satino training site of the Faculty of Geography, Lomonosov Moscow State University). To obtain the digital elevation model, we created a temporary geodetic network. The coordinates of the points were measured by the satellite positioning method using a highprecision mobile complex. The aerial survey was carried out using an unmanned aerial vehicle from a low altitude (about 40–45 m). The processing of survey materials was performed via automatic photogrammetry (Structure-from-Motion method), and the digital elevation model of the landslide surface on the Protva River valley section was created. Remote sensing was supplemented by studying archival materials of aerial photography, as well as field survey conducted immediately after the landslide. The total amount of research results made it possible to establish the causes and character of the landslide process on the study site. According to the geomorphological conditions of formation, the landslide refers to a variety of landslideslides, which are formed when water is saturated with loose deposits. The landslide body was formed with the "collapse" of the blocks of turf and deluvial loams and their "destruction" as they shifted and accumulated at the foot of the slope.
