Definition
In CARTOGRAPHY: a) a small area outside the NEAT LINES of a MAP or CHART included within the NEAT LINES or borders to avoid publishing a separate graphic of the small area alone; b) a representation of a small area on a larger SCALE (e.g., town-plan inset), or of a large area at a smaller SCALE (e.g., orientation inset); c) any information, not normally appearing within the geographic limits of a MAP, which has been enclosed by border lines and included within the map neat lines. Insets are always placed in areas where important features will not be obscured.
