“…Personal constraints or limitations such as physical disability, financial limitations, carbon footprint reduction, restricted geographical mobility, and safety concerns (Marín-Spiotta et al, 2020, Olcott & Downen, 2020, Giles et al, 2020 can prove too complex, or problematic, to overcome and prevent fieldwork. Access to outcrops that were previously accessible may no longer be permitted out of safety or environmental concerns (e.g., outcrops are too steep, or biota conservation limits access), because of land ownership changes (Chan & Kamola, 2017), increased vegetation, or a seasonal climate, weather, or high-latitude location (Senger et al, 2021).…”

“…These methods provide an invaluable resource for detailed investigation of outcrop models. Gigapixel technology and images have also been used as effective virtual teaching tools (Piatek et al, 2012, Senger et al, 2021. Fully integrated digital outcrop models and gigapixel imaging methods show promising results (Biber et al, 2018), and may provide the scale and context that physical fieldwork and outcrop visits also afford, if the outcrops allow for it.…”

“…Online digital outcrop model databases (e.g., e-Rock (Cawood & Bond, 2019), GeoTour3D, V3Geo (Buckley et al, 2021, GeoBase, Svalbox (Senger et al, 2021), Virtual Australia) have seen a rapid increase in generation and use, as do a growing set of geological models hosted on the generic 3D photo-realistic model site Sketchfab. These databases provide a valuable source of digital outcrop models for geoscientists that can be used for research activities, and most recently the development of new online teaching methods driven by the widespread expansion of the virtual classroom due to the Covid-19 pandemic (Sima, 2020).…”

Outcrops are routinely used for research and education purposes, and are a key component of geoscientific training. Fundamentally, re-evaluation of outcrop observations and reproducibility of results is critical for scientific advancement. Accessibility to the field and outcrops, however, remain problematic for several technical and societal reasons. Advances in the application of digital outcrop models to geoscience research and training have seen a significant rise in recent years due to technological innovation and user-friendly workflows. Herein we discuss the necessity to digitally capture outcrops to preserve them and the natural landscapes that have shaped the Geosciences. Examples of outcrop re-evaluation that reflect sedimentological concept and technique advances, only possible with digital outcrops, is presented. Digitally preserved outcrops' role as milieus for increased accessibility, inclusivity, and scientific reproducibility is discussed. The time has never been more appropriate, and the tools never more accessible, to preserve outcrops and promote a more open and inclusive environment for geoscience research, education, and training.

“…The orientation, vertical and lateral extent, and friability of outcrops are important factors that determine whether outcrops are accessible for geologic research. Data collection in the field requires that safety be prioritized, and small unmanned aerial vehicles (sUAVs,) also commonly known as drones, provide opportunities to collect data from outcrops that are otherwise difficult or impossible to observe safely (Nieminski and Graham, 2017;Mezghani et al, 2018;Senger et al, 2020). Further, drone images and videos can be processed via digital photogrammetry, such as Structure from Motion (SfM), to produce a georeferenced 3D digital outcrop model (DOM) (Whitmeyer et al, 2010;Westoby et al, 2012).…”

Small UAVs (drones) are increasingly useful for field data acquisition in the geosciences. Drone images and videos can be processed via digital photogrammetry to produce a 3D digital outcrop model (DOM). DOMs provide opportunities to "return" to an outcrop after fieldwork is complete, collect data from outcrops that are inaccessible, or may even provide opportunities to radically increase data volume of geometric characterizations of geological structures. Our study focuses on understanding the limitations of digital measurements and interpretations used to create stratigraphic columns by comparing 2D and 3D results to traditional stratigraphic descriptions and measurements from fieldwork.In this study, a drone collected photos and videos of a well-exposed section of the Palm Spring Formation in the Mecca Hills, California, which is divided into lower and upper units by an angular unconformity and a change in overall texture.

“…Destacam-se dois exemplos interessantes. O primeiro é a iniciativa Svalbox (https://www.svalbox.no/) (Senger, 2019;Senger et al, 2020) A terceira fase trata dos Produtos gerados e pós-processamento deles. A partir dos resultados do processamento, produtos como MDE, ortofotos e malhas triangulares podem ser gerados e manipulados de acordo com a aplicac ¸ão.…”

Agradec ¸o primeiramente aos meus pais, Rose e Roberto, por continuarem apoiando e dando total suporte para minhas decisões.Ao professor Carlos Grohmann, por acompanhar minha trajetória acadêmica desde a iniciac ¸ão científica, passando pelo trabalho de formatura, relatando o mestrado, e agora orientando o doutorado. Grande parte do que me tornei como pesquisadora se deve a sua dedicac ¸ão e paciência quase infinita.Ao Arthur Miyazaki, por ser um companheiro incrível, me apoiando, aturando e se esforc ¸ando para me manter feliz, além de revisar esta tese e me ajudar a tornar minhas ideias realidade.Ao amigo Arthur Endlein, pela parceria que se estende ao longo dos anos, rendendo bons frutos. Espero que possamos continuar crescendo academicamente juntos.Ao amigo Guilherme Garcia, que nesses 14 anos tem dividido muitas risadas e lágrimas comigo.Apesar do tempo, das diferenc ¸as e da distância, parmanecemos nos apoiando. E também ao amigo Renato Martinez, que mesmo de longe sempre se faz presente com palavras de apoio.À amiga Thaís Trevisani, por me apoiar, revisar esta tese, me levar para ver afloramentos incríveis e comemorar comigo as pequenas conquistas. Às amigas Amanda, Daiane, Natália e Pâmela, que me apoiaram de maneira decisiva para a conclusão da tese, mesmo quando duvidei de mim mesma.Aos servidores da Secretaria Municipal de Seguranc ¸a Urbana, especialmente à equipe Dronepol, pela oportunidade de aprendizado e cooperac ¸ão, que contribuiu para aumentar a significância da minha pesquisa.E finalmente, a todos os professores incríveis, membros do SPAMLab e IGC, e todos aqueles que, mesmo que eu tenha esquecido de mencionar, tornaram esse resultado possível.Muito obrigada.
