Fields
Name Description
Public field mAngleEnd
End angle in radians for radar sweep
Public field mAngleStart
Start angle in radians for radar sweep
Public field mAtmosphericCorr
Atmospheric correction value (1.0 for none)
Public field mCenterPoint
Center point in global coordinates
Public field mColor
Color to display view shed data in
Public field mDesc
View shed description
Public field mFilterRect
Optional rectangle for filtering view shed to a certain area of interest
Public field mFresnelFreq
Frequency (in GHz) to use for testing clearance of first Fresnel zone (use 0.0 to not do Fresnel testing)
Public field mFresnelPctClear
Percentage of first Fresnel zone that must be clear of obstacles (use 0.6 for 60%). If 0 is specified, the default of 60% is used.

Public field mRadius
Search radius in meters
Public field mReceiverAngle
Angle (in degrees) above horizon to test at (NULL for none)
Public field mReceiverAngleEnd
Angle (in degrees) above horizon to stop test at (NULL for none) - if this and mReceiverAngle are provided, an angle range view shed test is done (like a flashlight beam)
Public field mReceiverHeight
Height at which transmitter must be visible
Public field mReceiverHeightAbs
Is the receiver height absolute or relative to the ground?
