Abstract: In many developing countries, there are no special programmes which focus attention on the use of graphics in the geographic education of visually impaired people. However, there are increasing incidence of people with visual disability who quest for knowledge at the elementary, secondary and tertiary level of education. This study has therefore investigated the spatial awareness and geographic knowledge of visually impaired persons in Nigeria through their potential tactile map reading abilities. The main objectives of the study were (1) to test the ability of the visually disable to recognize and identify map symbols and thus determine their perception and understanding of spatial phenomena and (2) to identify the peculiar problems confronting the visually impaired person in tactile map use and environmental knowing. Sixty blind subjects at all levels of education across Nigeria were tested on 27 questions based on eight tactile maps. The result were used to verify the assumption that (1) lost of sight does not equate with mental limitation for environmental knowing, (2) discrete and varied map symbols texture help the visually impaired to understand geographic distributions, and (3) learning experience based on academic level and periods at which visual impairment
