Maps are one of the most important types of documents associated with exploration.
A map is a graphic representation that facilitates a spatial understanding of things, concepts, conditions, processes or events in the human world. They are used by explorers to help find their way. They are also prepared by explorers to document or record what in fact they discovered. There are many types of maps, each determined by the purpose for which it is designed. The road maps that your parents use are way-finding or route maps that guide them from one place to another.
