Maps used in the survey (Table 1 , Questions 23–25) showing three different map colour schemes: A) red-yellow sequential, B) blue-yellow sequential, and C) blue-yellow-red diverging. Maps were presented in both gradational shaded (left) and binned (right) data classification format simultaneously so that participants could visualise the colour schemes on different styles of map. Maps were viewed at 584 × 518 pixels.
