KMLViewSetter

Sets the view-related KML attributes for a group of features destined for the OGCKML Writer. Creation of LookAt or Camera views are supported.

Example

These transformer parameters are configured for a LookAt view type.

This is the resulting view of the selected area.

Usage Notes

For more information regarding KML:

See the FME OGCKML Writer chapter in the FME Readers and Writers manual (in Workbench, select Help > FME Readers and Writers Reference)
See the KML documentation: http://developers.google.com/kml/documentation/cameras

Configuration

Parameters

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.

Editing Transformer Parameters

Using a set of menu options, transformer parameters 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 beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

How to Set Parameter Values

Using the Text Editor

The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.

Text Editor

Using the Arithmetic Editor

The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.

Arithmetic Editor

Conditional Values

Set values depending on one or more test conditions that either pass or fail.

Parameter Condition Definition Dialog

Content

Expressions and strings can include a number of functions, characters, parameters, and more.

When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.

Content Types

String Functions	These functions manipulate and format strings.
Special Characters	A set of control characters is available in the Text Editor.
Math Functions	Math functions are available in both editors.
Date/Time Functions	Date and time functions are available in the Text Editor.
Math Operators	These operators are available in the Arithmetic Editor.
FME Feature Functions	These return primarily feature-specific values.
FME Parameters	FME and workspace-specific parameters may be used.
Creating and Modifying User Parameters	Create your own editable parameters.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.

Table Tools

Row Reordering

Enabled once you have clicked on a row item. Choices include:

Add a row
Remove a row
Move current row up one
Move current row down one
Move current row to top
Move current row to bottom

Cut, Copy, and Paste

Enabled once you have clicked on a row item. Choices include:

Cut a row - delete and copy to clipboard
Copy a row to the clipboard
Paste a row from the clipboard

Cut, copy, and paste may be used within a transformer, or between transformers.

Filter

Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output.

Import

Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers.

Reset/Refresh

Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers.

Note: Not all tools are available in all transformers.

Keywords: "Google Earth" KML

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.
