The sddsymbols.xml file is used to define symbols used to draw aircraft plots on the radar display.

The sddsymbols.xml file is located in the fir/theme/(theme_name) directory

Attribute	Format	Remarks
Root Element	symbols

Each symbol is drawn using the same methods as used in the maps:

The symbol is drawn using a cartesian system where the centre of the track is the centerpoint (0,0).

The following symbols must exist:

track_psr	Primary radar aircraft track
track_ssr	Secondary radar aircraft track
track_cmb	Primary + Secondary radar aircraft track
track_coasted	track of aircraft which has coasted (or disconnected)
