The GM_ViewShedParams_t type exposes the following members.

Public methodGM_ViewShedParams_t
Default Constructor
Public methodEquals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetHashCode
Serves as a hash function for a particular type.
(Inherited from Object.)
Public methodGetType
Gets the type of the current instance.
(Inherited from Object.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodStatic memberSizeOf
Returns the size of the unmanaged structure
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
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?
Public fieldmShowHiddenPoints
Make hidden points visible instead of viewable points.
Public fieldmShowProgress
Display view shed calculation progress?
Public fieldmSize
Size of structure in bytes
Public fieldmTransmitterHeight
Transmitter height in meters
Public fieldmTransmitterHeightAbs
Is the transmitter height absolute or relative to the ground?
Public fieldmUseEarthCurvature
Use the curvature of the earth in the analysis?
Public fieldmVectorElevsAbs
Are vector elevations absolute (i.e. relative to sea level) or relative to ground level?
Public fieldmVectorLayerList
List of vector layers to use features with elevation attributes from
Public fieldmVectorLayerListCnt
Number of vector layers in list
Public fieldmXSpacing
X sample spacing (use 0.0 for default spacing)
Public fieldmYSpacing
Y sample spacing (use 0.0 for default spacing)
