KMLPropertySetter

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.

If the description contains HTML content, the HTML may require additional files in order to be rendered correctly. Common examples are images, CSS stylesheets and javascript files. The Additional Files parameter may be used to specify the files which are required by the HTML in a feature. The required files should be listed in the “Source File” column. The “Path in Dataset” column may be used to specify where the file should be located within the output KML dataset. Typically, the value in the “path in Dataset” column should just be set to the same path as is given in the HTML. For example, if the HTML contains the following:

<img src=”images/pic.jpg”/>

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.

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.

Conditional Values

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

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.

Note: Not all tools are available in all transformers.
