protected double computeAzimuthLabelOffset ( double radius , double maxRadius ) { return Math . asin ( AZIMUTH_LABEL_OFFSET * maxRadius / radius ) ; }
compute an angular offset to apply to a azimuth label . this angle will be added to the azimuth of the label ' s azimuth in order to place the label a little bit to the side of the line that it applies to .
