Sets the view-related KML attributes for a group of features destined for the OGCKML Writer. Creation of LookAt or Camera views are supported.
Parameters
Location
Longitude, Latitude, Altitude
These parameters specify a location associated with the View Type parameter.
Altitude Mode
Specifies how KML Viewers, such as Google Earth, should interpret the altitude value.
View
View Type
If the View Type is LookAt, this location is the focal point of the view (where the view is looking at). In most cases, this is the view type you will choose. If you determine, for whatever reason, that it is too limiting, you can set the view type to Camera.
If the View Type is Camera, this location is the location of the camera (where the view is looking from).
Heading
Heading specifies the rotation, in degrees, of the view around the Z axis, relative to North.
Tilt
Tilt specifies the rotation, in degrees, of the view around the X axis. A value of 0 indicates that the view is aimed straight down, and a value of 90 indicates that the view is aimed toward the horizon.
Values greater than 90 only apply if the View Type is Camera, and indicate that the view is pointed towards the sky.
Roll
Roll specifies the rotation, in degrees, of the view around the Z axis, after the Heading and Tilt rotations have been applied. This value only applies to Camera views, and is generally not necessary.
Range
Range specifies the distance, in meters, that the view location is viewed from. This value only applies to LookAt view types.
Time
The parameters in the Time section allow the view to be active at a specific point or period of time.
Type
This parameter determines the type of KML time primitive that will be created. Possible options include Timestamp and Time Period. Select ‘None’ if you don’t wish to associate a time with the view.
Timestamp
This parameter specifies the value of the timestamp if the time type is Timestamp. The value can either be in the FME DateTime format, or the XML Schema time format.
Period Start
This parameter specifies the beginning of the time period if TimePeriod is the selected time type. The value can either be in the FME DateTime format, or the XML Schema time format.
Period End
This parameter specifies the optional end of the time period if TimePeriod is the selected time type. The value can either be in the FME DateTime format, or the XML Schema time format.
Example
These transformer parameters are configured for a LookAt view type.
This is the resulting view of the selected area.

Editing Transformer Parameters
使用一组菜单选项,变压器参数s can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click
