Revamp and development of Chile’s National Tourism Service pictogram system. A study of their symbols and the international standards led to the design of a new system composed of 135 pictograms to include both new categories in services, activities and tourist attractions, and pictograms for Chile’s National Forest Service (CONAF) and National Monuments Board. In addition, a validation strategy was carried out to test the use of the new pictograms in maps, signage and brochures.
