Cars have sat nav systems, mobile phones use GPS: maps are important in everyday life whether captured by aerial photography, satellite imagery or simply drawn. This unit looks at how we read and evaluate the information in maps and assesses the values embedded within them. From mental maps to public transport and street maps: how do they affect your life? This study unit is just one of many that can be found on LearningSpace, part of OpenLearn, a collection of open educational resources from The Open University.
