![]() PositionĪ TacticalSymbol’s position indicates the latitude, longitude, and altitude where the symbol draws its graphic. The above example omits the modifiers parameter, so the symbol contains only the attributes indicated by its symbol identifier. In the case where both the symbol identifier and the modifiers list indicate the same attribute, the modifiers list has priority. The modifiers list extends the symbol attributes already indicated by the symbol identifier. This parameter may be null or omitted entirely. In the above example, (34.7327, -117.8347, 1000) places the symbol 1km above sea level and north of Los Angeles.Īn optional list of key-value pairs specifying supplemental graphic and text attributes. The latitude, longitude, and altitude where the symbol is drawn on the globe. In the above example, “SFAPMFQM-A” defines a friendly Special Operations Forces drone aircraft. The symbol’s shape, fill color, outline color, and icon are all defined by the symbol identifier. In the case of MIL-STD-2525, the symbol identifier is a 15-character alphanumeric symbol identification code (SIDC). The format of this identifier depends on the symbol set. MilStd2525TacticalSymbol’s constructor accepts the following parameters:Ī string identifier indicating the tactical symbol’s appearance. We then added the TacticalSymbol to a RenderableLayer we created. We’ve created and displayed a TacticalSymbol representing a friendly Special Operations Forces Drone Aircraft from the MIL-STD-2525 symbology set by creating a MilStd2525TacticalSymbol with the appropriate symbol identifier string.

This guide shows how to use WorldWind tactical symbols in your application, and is organized into five sections:Įach symbology set defines a tactical symbol implementation that derives from the TacticalSymbol interface. TacticalSymbol provides an interface to common tactical symbol functionality, and extends the Renderable interface so you can add a TacticalSymbol directly to a RenderableLayer. The tactical symbols Java Web Start demo showcases how tactical symbols appear and behave in a WorldWind based application. Department of Defense’s Common Warfighting Symbology set, MIL-STD-2525C. This guide covers tactical symbols belonging to the U.S. In general, the graphic displayed depends on the symbology set a tactical symbol belongs to. The graphic displayed is typically a screen icon with supplemental text and graphics surrounding the icon. A tactical symbol displays graphic and textual information about an object at a single geographic position at a particular point in time. ![]()
