DATA-BASED GEOLOGIC MAPPING COURSE

We developed and delivered a course titled “Data-Based Geologic Mapping” aimed at instructing undergraduate and graduate students on the theory and applied methods for geologic mapping using remotely-sensed data. Techniques for producing these types of maps were initially developed for Apollo-era planetary scientists exploring the Moon, and the advent of geographic information systems (GIS) has widened the ability of geoscientists to study remotely-sensed data in a variety of settings, e.g., drone data of a coastal region or bathymetry data of the seafloor. This course used planetary and Earth study sites to introduce students to data-based mapping and teach them to incorporate field-based geologic investigations to enhance scientific exploration. Improved mapping capabilities come with practice, therefore, 3 different geologic maps were generated per student using the same workflow. Through this, students developed familiarity with GIS, confidence in troubleshooting problems, and a sense of creativity for representing varied geology in diverse environments. The course had the following learning goals: (1) Appreciate the complexity of data-based geologic maps, critically examine published maps, and creatively address mapping ambiguities in their own research; (2) Be able to pose scientifically feasible mapping projects, including considerations for map scale, area, and theme, what data to use, and what standards to adhere to; (3) Conduct the GIS workflow for producing data-based geologic maps, including how to create, manage, and package file geodatabases; (4) Compile and draft all map components, supplementary data and documentation, map sheets, and related presentation materials. Prerequisites for the course included a basic understanding of information presented in geologic maps, foundational geologic principles and general geomorphologic signatures, and for undergraduates, completion of ASU’s Field Geology I course. Knowledge of ArcGIS software was not required.
