A sector of space is a physical area of space within a planetary system. Sectors are used to provide orientation to navigators and pilots in areas which would otherwise have no direction markers. To define a sector, cartographers typically lay a three dimensional grid over a planetary system and chart areas into equal sections. Once this is approved by the government, official sectors are declared and released to the public. Sizes of sectors will vary depending on a system. Human and Xi’an governments both utilize sectors in mapping.
