Applications of modern digital mapping systems to Assist inclusion of persons with disabilities in geoscience education and research

摘要

? 2022 Elsevier LtdNew and emerging technologies are changing the world as we know it, and how we choose to perform geologic fieldwork is changing as well. Recent developments in hardware and software provide unprecedented opportunities not only for conventional field studies but also for persons traditionally exempt from field-related research because of mobility issues or inability to travel. Geographic Information Systems (GIS) first allowed digital geologic mapping in the field, and these systems remain in widespread use because of ease of use and ease of data duplication for collaboration in work teams or field classes. We present a general 2D workflow based on GIS approaches that affords opportunities for physically disadvantaged individuals that includes cognitive steps driven by the data assembly process in GIS. Most notable is the digitization of linework and exploration of an area with Google Earth Pro (GEP) as steps, outside the field, that allow assessment of an area to formulate hypotheses that can be done by a physically disadvantaged person as well, or better, than those physically capable of field exploration. We then explore emerging technologies including pseudo-3D viewing using image drapes on an elevation model (aka 2.5D method) and true 3D approaches based on Structure-from-Motion photogrammetry that provide a powerful toolbox back at the office or at base camp that does not require physical abilities or direct field access. These 3D tools are potentially transformative for mobility impaired individuals that could allow them to work individually, or as part of a team, to assess field related problems. For all 3 levels of digital mapping (2D, 2.5D and 3D) we emphasize specific workflows designed to help the researcher perform digital geologic mapping with a specific focus on individuals with limited mobility. Some or all of what we suggest here, however, is of benefit to any field geologist and can be used to augment, or completely perform field studies.
