Tactile Maps

For Students who are Blind or Visually Impaired

This section addresses the creation of tactile maps, including their design and method of production. Starting with a brief look at the history of tactile maps, it explores the advantages of various styles, materials, and techniques, from simple relief maps through online mapping and high-tech developments.
