Abstract:
A method for displaying situational awareness information, comprising:selecting a map center coordinate; determining an angle between an axis passing through the map center coordinate and a first ray beginning at the map center coordinate and passing through a point of interest; determining a distance between the map center coordinate and the point of interest; selecting a circular range band with an inner and an outer edge as well as a thickness; determining if the point of interest is located between the inner and the outer edge of the circular range band, and if so, determining a ratio of the distance along the ray that the point of interest lies with respect to the thickness of the circular range band; selecting an area for projecting on a screen display having a screen coordinate; and selecting a display band having a thickness that is projected on the screen display such that the point of interest located in the circular range band is projected on the screen display within the display band along a second ray extending from the screen coordinate at the angle and located within the display band with the ratio relative to the thickness of the display band.
