Description

For convenience. Defines the positions and optional per-marker parameters of markers in a marker batch using Cartographic positions. Longitude and latitude are in radians, and altitude is in meters. This is equivalent to converting each position in positions to Cartesian and calling Set.

Syntax

[Visual Basic .NET]
Public Sub SetCartographicWithOptionalParameters( _ ByVal CentralBody As String, _ ByRef Positions() As Variant, _ ByVal OptionalParameters As IAgStkGraphicsMarkerBatchPrimitiveOptionalParameters _ )

[Visual Basic .NET]

Public Sub SetCartographicWithOptionalParameters( _
   ByVal CentralBody As String, _
   ByRef Positions() As Variant, _
   ByVal OptionalParameters As IAgStkGraphicsMarkerBatchPrimitiveOptionalParameters _
)

Parameters

CentralBody: The central body the positions are defined on.
Positions: An array containing the new positions for markers in the marker batch, provided in the order latitude, longitude, altitude.
OptionalParameters: Optional per-marker parameters corresponding to positions. Each per-marker parameter must have the same number of elements as positions.

Remarks

See Set for a full discussion.

Example

Shows the format of the Colors, Positions and Indices parameters when updating a marker batch primitive with cartographic positions.
