Syntax

public struct GM_ClassifyNoiseSetup_t

The GM_ClassifyNoiseSetup_t type exposes the following members.

Constructors

	Name	Description
	GM_ClassifyNoiseSetup_t	Constructor to set values directly.

Fields

	Name	Description
	mFlags
	mMaxValidElevM	Maximum valid elevation in meters. Anything higher is marked as high noise. Use INVALID_ELEV_VALUE to not add this check
	mMaxValidHeightM	Maximum valid height above ground in meters. Anything higher is marked as high noise. Use INVALID_ELEV_VALUE to not add this check
	mMeanGridBinMult	Grid size for finding noise
	mMinHighNoiseOffsetM	Minimum offset in meters above from local max average to possibly be high noise. Prevents small offsets in mostly flat areas, like individual power line points.
	mMinLowNoiseOffsetM	Minimum offset in meters below from local min average to possibly be high noise. Prevents small offsets in mostly flat areas, like individual power line points.
	mMinNoiseStdDev	Minimum number of std dev from mean point needs to be for noise.
	mMinValidElevM	Minimum valid elevation in meters. Anything lower is marked as low noise. Use INVALID_ELEV_VALUE to not add this check
	mMinValidHeightM	Minimum valid height above ground in meters. Anything lower is marked as low noise. Use INVALID_ELEV_VALUE to not add this check
	mMovingWindowSize	Number of pixels on each side of moving window for checking noise (i.e. 5 is a 5x5 set of cells around cell sample is in)
