GIS in Action 2026

Blind and low vision map users rely on tactile materials to orient and navigate themselves in locations they frequent. While simplification of these maps for tactile legibility with traditional production methods typically omits elevation data, the increased availability of 3D printing production allows for the incorporation of 3D terrain and symbol elements into tactile cartography. Tactile cartography requires a different design approach than visual cartography and the incorporation of 3D printed elements add additional haptic variables that change the design approach. Locations with varied terrain and complex way finding can greatly benefit from incorporating 3D design elements in their tactile maps which can provide these users with more safety and confidence when navigating these areas. Explore the design and production of 3D tactile terrain models of the Portland Community College Sylvania Campus for the benefit of blind and low vision students and faculty.
