Fields
NameDescription
Public fieldmAngleEnd
End angle in radians for radar sweep
Public fieldmAngleStart
Start angle in radians for radar sweep
Public fieldmAtmosphericCorr
Atmospheric correction value (1.0 for none)
Public fieldmCenterPoint
Center point in global coordinates
Public fieldmColor
Color to display view shed data in
Public fieldmDesc
View shed description
Public fieldmFilterRect
Optional rectangle for filtering view shed to a certain area of interest
Public fieldmFresnelFreq
Frequency (in GHz) to use for testing clearance of first Fresnel zone (use 0.0 to not do Fresnel testing)
Public fieldmFresnelPctClear
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 fieldmGenCoveragePolys
Generate area/polygon features for the covered area (these are vector and exportable to vector formats)
Public fieldmRadius
Search radius in meters
Public fieldmReceiverAngle
Angle (in degrees) above horizon to test at (NULL for none)
Public fieldmReceiverAngleEnd
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 fieldmReceiverHeight
Height at which transmitter must be visible
Public fieldmReceiverHeightAbs
Is the receiver height absolute or relative to the ground?
