Mobile GIS in geologic mapping exercises
Klauis Neumann, Michael Kutis 2006 Journal of Geoscience Education v54 p147-152
We have been developing and teaching the components of mobile GIS in Field Methods courses and will be incorporating them into Structural Geology exercises. Since the bedrock in east central Indiana is topographically invariant, non-inclined, and often not exposed, we have developed a new introductory GIS project that simulates structural features. It utilizes inclined, one-foot square planes that are placed upon a series of pedestals stationed in an open area, each accompanied by a petrographic hand sample and an age label. An introductory one-hour session is held in the field to teach acquiring GIS data. Then the students independently acquire geologic data such as GPS-located "outcrop" locations, rock descriptions, and strike/dip, and enter the geologic data on a base map using Mobile GIS software (ArcPad). In a two-hour follow-up class students learn to add their field data to a map in the PC-based GIS program ArcMap. Strike/dip symbols are computer-generated and displayed at the GPS coordinates taken in the field. This exercise supports spatial organization with data availability of Mobile GIS in the field and prepares students for GIS-based mapping projects in our Field Camp in Wyoming.
