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.

Usage Notes

For more information regarding KML:

 Configuration

Parameters

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 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.

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

Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click beside the applicable parameter.

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.

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.

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.

Table Tools

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

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.
