Popis:	This paper describes the process of building a GIS for use in real time by blind travellers. Initially the components of a Personal Guidance System (PGS) for blind pedestrians are outlined. The location finding and database components of the system are then elaborated. Next follows a discussion of the environmental features likely to be used by blind travellers, and a discussion of the different path following and environmental learning modes that can be activated in the system. Developments such as personalizing the system and accounting for veering are also presented. Finally, possible competing schemes and problems related to the GIS component are examined.
