Accessible graphics

摘要

Geoscience teaching naturally pairs well with visual resources. Textbooks use colour graphics, photographs, and diagrams liberally, and many geological concepts are explained using maps and images of outcrops. But how can geoscience teachers help those with a visual disability access this wealth of geoscience imagery and knowledge in a way that is meaningful and helpful? Now an online resource, the Geological Tactile Image Repository (tactileimages.theiagd.org), puts tactile graphics into the hands of geoscience students with visual impairments.
