Locations are the smallest unit of space in Dawn 2055. They are represented by a square on the map grid and are defined by coordinates, a series of four numbers separated by periods. The first pair of numbers corresponds to the sector, and the second pair corresponds to your location in the sector (e.g: 126.96.36.199 means: "The 12.7 location in sector 11.7").
On certain squares, random events can occur.
Actions can be performed depending on the type of terrain you are on (Settlements are a special case, please see the link) :
