Vexillological Symbol
Flag information symbols are used by vexillologists to indicate certain characteristics of flags, such as where they are used, who uses them, and what they look like.
The symbols were created by vexillologist Whitney Smith and then adopted by the International Federation of Vexillological Associations (FIAV) in the early 1970s. Vexillologist Željko Heimer added the symbols for 
normal and 
historical in the early 1990s.

Usage symbols
The usage symbols are based on a grid of two rows representing use on land and use on water, and three columns representing private use, public use, and military use. Each circle in the grid indicates the flag has one or more of the following six basic usages:
| Private | Public | Military | |
|---|---|---|---|
| Land | Civil flag Flown by private citizens on land | State flag Flown by the government on land | War flag Flown by the military on land |
| Water | Civil ensign Flown by private vessels | State ensign Flown by government vessels | Naval ensign Flown by military vessels |
A single design may be associated with no usages or multiple usages. Heimer suggested an additional row for air ensigns, but it has not been adopted by FIAV. The air ensign row refers to flags displayed on aircraft, including when on the ground, and air installations. The air ensign row is placed above the remaining two rows.
