“…Based on measurements from recent LiDAR scans and field estimates of depth to the sliding surface, this "partially slipped area" (PSA) has an approximate volume between 2.7 and 6.75 × 10 4 m 3 , with the toe of the area terminating only 20 m above the existing carriageway. Since completion of the A40 in 1968, monitoring through to 2005 found no further displacement (Smedley et al, 2009), and a comparison of LiDAR data between 2006 and 2020 confirms that no widespread movement has occurred recently. Nonetheless, the presence of a large unstable mass above a strategically significant highway in an area of historic landslide activity still poses a significant, if not immediate, risk to the A40 dual carriageway.…”

Developments in time-lapse electrical resistivity tomography (ERT) technology are transforming our ability to monitor the subsurface due to purpose-built monitoring instruments, advances in automation and modeling, and the resulting improvements in spatial and temporal resolution. We describe the development of a novel ERT-based remote monitoring system called PRIME that integrates new low-power measurement instrumentation with data delivery, automated data processing and image generation, and web-based information delivery. Due to the sensitivity of ERT to hydrologic processes in the near surface, we focus on the application of PRIME for moisture-driven landslide monitoring. Case examples are considered of landslides in engineered and natural slopes, including those impacting geotechnical assets in rail and highways, where slope hydrology is seen to be controlled by lithology, vegetation, fissuring, and drainage structures. We conclude by taking a forward look at emerging developments in ERT monitoring relating to hardware, software and modeling, and applications.

“…Pesquisas com imagens de satélite (Forest canopy cover -CC), métrica amplamente usada para várias aplicações de gerenciamento de recursos naturais [26] ou com a tecnologia LiDAR (Light Detection And Ranging) são mais comuns, mas apresentam baixa resolução, no primeiro caso e custos proibitivos no segundo [27,28], apesar de gerar nuvens de pontos 3D e modelos digitais do terreno por meio de feixe laser [29].…”

Com a finalidade de se investigar a aplicação da fotogrametria com VANT no âmbito de estudos técnicos e ambientais em rodovias, relacionadas às zonas livres, foram realizadas coletas de imagens com um quadricóptero e sensor embarcados em um veículo terrestre. Os objetivos específicos foram avaliar os resultados de (i) estimativa do diâmetro à altura do peito (DAP) e, respectivamente, a cada árvore selecionada, a (ii) estimativa de sua distância ao bordo da pista, estimativas essas oriundas de uma nuvem de pontos tridimensional gerada a partir das imagens oblíquas terrestres obtidas a curta distância. Para se efetivar as comparações das estimativas supracitadas, foram coletados os valores referentes à verdade de campo usando-se métodos e equipamentos tradicionais. Os resultados das comparações entre os dados estimados através da reconstrução 3D e daqueles pelos métodos convencionais, no âmbito do DAP e da distância ao bordo da pista, se mostraram promissores, com correlação estatística fortíssima e RMSE de 2,62 cm e 8 cm, respectivamente. Conquanto seja importante outros estudos com maior número de indivíduos envolvidos, os resultados apontam para uma possibilidade de aplicação, mesmo sendo um nicho pouco explorado por pesquisadores.

“…LiDAR has been utilized to quantify slope movement and to predict and measure landslides as well as rockfall and other hazards and instabilities along roadways [30,70,116]. LiDAR has also been used with optical remote sensing images for posthazard assessment of structural damage of buildings [98].…”

Introduction Evaluating the condition of transportation infrastructure is an expensive, labor intensive, and time consuming process. Many traditional road evaluation methods utilize measurements taken in situ along with visual examinations and interpretations. The measurement of damage and deterioration is often qualitative and limited to point observations. Remote sensing techniques offer nondestructive methods for road condition assessment with large spatial coverage. These tools provide an opportunity for frequent, comprehensive, and quantitative surveys of transportation infrastructure. Methods The goal of this paper is to provide a bridge between traditional procedures for road evaluation and remote sensing methodologies by creating a comprehensive reference for geotechnical engineers and remote sensing experts alike. Results A comprehensive literature review and survey of current techniques and research methods is provided to facilitate this bridge. A special emphasis is given to the E. Schnebele ( ) · G.
