A user-centered mapping design for geomorphological hazard thematic map

Numerous studies have concentrated on developing user-centered designs for hazard zone maps but rarely for hazard-oriented geomorphological maps, named as Geomorphological Hazard Thematic Maps (GHTMs) in this study, which provide more detailed information about natural hazards. This study developed a user-centered mapping design for GHTMs for nonexperts in geomorphology. We invited civil engineers and high school educators to evaluate a sample GHTM’s design in group and focus group panel interviews. The civil engineers preferred maps with more geomorphological features, whereas the educators preferred simple designs. Both groups indicated that the inclusion of essential facilities and road networks is essential. The map was also adjusted by adding hillshade layer and by changing the symbology for mass wasting, fault scarps, and fluvial features to increase clarity and simplicity. This case study is the first step toward developing user-centered mapping designs for hazard communication that will deepen their understanding of natural hazards.This study developed and explored a user-centered design for a geomorphological hazard thematic map.Civil engineers and educators were invited to provide feedback.The engineers preferred detailed designs, and the educators preferred simplified designs.Both groups considered essential facilities and roads useful reference points.This study offers a geomorphological mapping design for nonexperts in geomorphology.
