Sets common properties for groups of vector and raster features destined for the OGCKML Writer.
Name specifies the text that will be displayed in the navigation tree of a KML Viewer such as Google Earth. If the feature has a point geometry, it will also be used as the label text.
Summary specifies the text that will be displayed below the feature's name in the navigation tree of a KML Viewer such as Google Earth.
Visibility specifies whether or not the feature will be visible by default when the user first opens the dataset. If the visibility is set to No, the feature will not be displayed. However, the visibility may still be toggled in the navigation tree of a KML Viewer such as Google Earth.
Content Type specifies the type of the feature's balloon content. If the type is Text, the contents will be XML entity-encoded when written to the KML file. If the type is HTML, the contents will not be XML entity-encoded, but preserved in such a way that the content will be displayed as valid HTML.
Content specifies the text or HTML description to be displayed in the feature's Balloon.
Include Attribute Table specifies whether or not a table of the features attributes should be included in the Balloon Content.
If the Include Attribute Table parameter is set to Yes, the value of this parameter will be used as the title of the attribute table.
The “Path in Dataset” cell would be set to “images/pic.jpg”. If a cell is empty, the corresponding source file will be copied into the root folder of the dataset. If an absolute path is given (for example, /images/pic.jpg), the path will be resolved relative to the root file of the dataset. If a relative path (for example, images/pic.jpg) is given, the path will be resolved relative to the KML file which contains the current feature.
Geometry Type specifies the type of geometry properties to apply to the feature.
Altitude Mode specifies how KML Viewers, such as Google Earth, should interpret the z value of features with vector geometry, or the altitude setting for features with raster geometry.
The draw order determines the order in which features are displayed. Features with a higher value will be displayed over features with a lower value. This applies to overlay features and features with line geometries.
Raster Altitude specifies the altitude, in meters, at which the raster tile should be displayed. This option is not commonly required.
Raster Opacity specifies the opacity of raster tile when displayed in a KML Viewer, such as Google Earth. This value is a display directive only, and has no effect on the underlying raster geometry.
Extrude specifies whether or not to connect the geometry of vectors to the ground. KML Viewers, such as Google Earth, will not display extruded geometry unless the Altitude Mode is Absolute, Relative To Ground, or Relative to Sea Floor.
This option only applies to linear geometries, not points or polygons.
While the Altitude Mode parameter sets the behavior of the line vertices, this parameter sets the behavior of the line segments between the vertices. If Follow Terrain is set to Yes, the line segments between vertices will conform to the terrain. If Follow Terrain is set to No, the line segments will be a straight line from one vertex to the next. This will cause the line to hover above low terrain, and be buried underneath higher terrain.
KML Viewers, such as Google Earth, will not enable terrain following unless the Altitude Mode is Clamp To Ground or Clamp To Sea Floor.

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.
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.
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.
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.
Set values depending on one or more test conditions that either pass or fail.
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.
|These functions manipulate and format strings.|
|A set of control characters is available in the Text Editor.|
|Math functions are available in both editors.|
|Date/Time Functions||Date and time functions are available in the Text Editor.|
|These operators are available in the Arithmetic Editor.|
|These return primarily feature-specific values.|
|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.
Enabled once you have clicked on a row item. Choices include:
Cut, Copy, and Paste
Enabled once you have clicked on a row item. Choices include:
Cut, copy, and paste may be used within a transformer, or between transformers.
|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 populates the table with a set of new attributes read from a dataset. Specific application varies between transformers.|
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.
