Sonic maps

Information sonification or auralisation (described in Assistive Technologies) is an example of using one sensory pathway to replace another that is impaired. Sonification or auralisation involves converting visual information into sounds. In geography, there have been sporadic efforts at using sound in sensory substitution mode, but with mixed success. One early example is the experimental software developed by Fisher (1994) to convey the uncertainty of information in raster (i.e. grid-cell) datasets acquired from remote-sensing satellites.
