To increase the comprehensibility of university textbooks, various tools, including various visual tools, can be used. This study aims: (1) to identify modern supplementary visual tools that complement geographical concepts teaching in university textbooks, and (2) to examine the characteristics and applications of these tools. To achieve the goals, a qualitative content analysis method was used. The findings indicated the identification of five modern visual tools: (1) aerial photographs, (2) satellite images, (3) GIS, (4) Google Earth, and (5) Google Earth Engine. Each of these visual tools has their own unique characteristics and applications in teaching geographical concepts. By searching the Noormags database, relevant articles were selected and analyzed in a targeted manner. Based on the findings, using modern and supplementary visual tools to teach geographical concepts in university textbooks can make this book a richer resource, and improve students' theoretical knowledge and their ability to analyze and produce spatial data as well.
