Map Symbol Visualization¶

Class symbol¶

class symbol¶

The symbol provides visualization of aeronautical map symbols. Each instance represents a single symbol in the visualization environment.

symbol instances have the following methods:

symbol.setSymbolType(type)¶

The setSymbolType() method changes type of the displayed map symbol. The following standard symbols are supported:

type	icon
def
dme
fix
ndb
tacan
vor
vordme
vortac
wpt

symbol.setColor(red, green, blue, alpha)¶

The setColor() method changes color of the symbol cone. The alpha value determines transparency of the cone.

symbol.setLocation(latitude, longitude, altitude)¶

The setLocation() method changes the symbol location. The latitude and longitude must be specified in geodetic coordinates.

The altitude is a 2-tuple (value, "AGL"), or (value, "AMSL") to specify the altitude Above Ground Level (AGL), or Above Medium Sea Level (AMSL). The altitude value is specified in meters.

symbol.setScale(scale)¶

The setScale() method changes the symbol scale. The symbol will be proportionally magnified for scale > 1.0.

Import of Navigation Database Data¶

Helper functions were implemented for automated import of X-Plane navigation database.

import _ossimPlanet
globe = _ossimPlanet.ossimPlanet()
# ... globe initialization

import xp_fix
fix = xp_fix.load(globe, "share/data/fix.dat")

import xp_nav
nav = xp_nav.load(globe, "share/data/nav.dat")

while not globe.renderDone():
  globe.renderFrame()
