What does topo mean?
Topo is an informal noun meaning a topographical map, particularly a map that represents hills, valleys, paths, and other features of the terrain through contour lines and symbols. It is used frequently by hikers, climbers, runners, and outdoor guides, who may speak of studying, reading, downloading, or carrying a topo. In computing and mapping contexts, it can also refer to a digital topographic map or map file. The word is essentially a shortened form of “topographical map” and has a practical, conversational character rather than the formal tone of the unabbreviated expression. Although topo can describe any map showing physical geography, it is particularly associated with navigation in the outdoors, where terrain detail is more important than the simplified representation found on an ordinary road map.

Where does topo come from?
The word “topo” is a shortened form of “topographic” or “topographical map,” used colloquially during the 20th century. The longer words belong to the family of “topography,” which combines the combining form topo- with the Greek suffix -graphia, meaning writing or description. Topo- ultimately derives from Greek topos, meaning “place.”
