Locations are the smallest unit of space in Dawn 2055. They are represented by a tile on the map grid, that is defined by coordinates, a serie of four numbers separate by dots. The first serie of two numbers corresponds to the sector, and the second serie corresponds to your location in the sector (e.g: 18.104.22.168 means: "The 12.7 location in sector 11.7").
On certain tiles, 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) :
