| GM_ClassifyNoiseSetup_t Fields |
The GM_ClassifyNoiseSetup_t type exposes the following members.
| 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) |
