Member Function Documentation

◆ AdjustAltitude()

void WsfEM_ALARM_Terrain::AdjustAltitude	(	WsfPlatform *	aPlatformPtr,
		double	aLat,
		double	aLon,
		double &	aAlt )

static

Adjust the incoming altitude so it more closely corresponds to that which would have been determined by stand-alone ALARM.

WSF utilizes bi-linear interpolation the get the altitude between terrain posts while ALARM does not. This can lead to some minor differences in the results (especially at close ranges), making it hard to compare results.

This isn't strictly necessary, but it was found to be useful when making sure everything worked in the converted code.

Parameters

aPlatformPtr	The platform containing the object represented by the incoming position.
aLat	The latitude of the point whose altitude is to be adjusted.
aLon	The longitude of the point whose altitude is to be adjusted.
aAlt	On input this is the WSF MSL altitude. On output it will be the ALARM MSL altitude.
