3D Landform Modeling to Enhance Geospatial Thinking

Abstract

Geospatial thinking is essential to the visualization–interpretation processes of three-dimensional geographic information. The design of strategies for the interpretation of the Earth’s surface which allow the development of students’ geospatial thinking poses a challenge in higher education. In geospatial education, we often see a practical approach where students are trained in specific GIS and/or geotechnologies. However, in the first stages of geospatial education, geographic literacy and geospatial thinking processes can be supported better through easy-to-use technologies. In this paper we show the results of two workshops performed with engineering students using visuospatial displays in an easy-to-use 3D software environment. This teaching approach improved students’ geospatial thinking, measured using the Topographic Map Assessment (TMA) test—a battery of seven tasks related to relief interpretation along with 18 exercises. Participants also completed a questionnaire relating to the following usability topics: operation (application), improvement, implications for education, and understanding of the concepts related to relief interpretation. The results showed mean gains between 10.7% and 12.6% of the highest score for the TMA. This, together with the results of the questionnaire, confirms the usefulness of this teaching approach using easy-to-use 3D technologies for developing geospatial thinking.
