Exploring Geological Map Usability Through Sequence Chart Visualization

Q: Why are geological maps cognitively demanding compared to many other thematic maps?

A: Geological maps integrate dense symbol systems, stratigraphic conventions, and multiple auxiliary elements such as legends, cross-sections, and schemas. Interpreting relationships between surface patterns and geological processes typically requires prior domain knowledge and familiarity with geological notation.

Q: How does geological training influence visual attention during geological map reading?

A: Participants with geological education tend to allocate a larger share of visual attention to map content and task-relevant geological features, while spending relatively less time on legends and explanatory elements. Participants without such training rely more on supportive components to interpret symbols and structures.

Q: What function do geological cross-sections serve in geological map interpretation?

A: Geological cross-sections provide vertical information about subsurface structure that complements the plan-view map representation. Effective use of cross-sections depends on understanding geological conventions, which affects how quickly users identify and interpret these elements.

Q: Which usability issues commonly affect web-based geological map applications?

A: Difficulties include non-obvious placement of core functions, ambiguous icons for base-map switching, and complex layer management interfaces. Such design choices increase visual search time and interaction effort across user groups.

Q: How does professional background shape interaction patterns with paper geological maps?

A: Participants with geology or geography backgrounds spend a greater proportion of viewing time on geological units and spatial structures, whereas geoinformatics-trained participants attend more to legends and schematic elements. These differences align with variations in disciplinary training and map-use experience.

Q: What methodological constraints arise when analyzing eye movements on paper geological maps?

A: Large physical map formats limit automated area-of-interest detection and often require manual or semi-manual gaze assignment. Such procedures increase processing effort and introduce potential observer-dependent variability into the analysis.
