CityGML Reader Parameters

If set to Yes (the recommended setting), this parameter reads the core CityGML schema files as well as the schema files specified in either xsi:schemaLocation attribute in the XML document or ADE_XSD_DOC directive to determine the feature types and feature attributes of the dataset.

It is recommended that this parameter be set to Yes for new workspaces and mapping files reading CityGML 1.0, 1.1 and various ADE datasets.

Note: You can duplicate the CityGML reader’s behavior for workspaces older than FME 2012 by setting this parameter to No. Please note that setting this parameter to Yes is not backward compatible if the dataset contains NoiseADE data.

This parameter can be used only if the Reader Driven by CityGML Schema parameter is set to Yes. The schema files specified in this directive will override those specified in xsi:schemaLocation attribute in the XML document.

This parameter can be used to tell the reader to ignore the schema files that are specified in the xsi:schemaLocation attribute of the root element in the dataset. This is particularly useful if the file locations specified in xsi:schemaLocation are not valid file paths.

This parameter is applicable only in scenarios when the reader dataset field is empty.

For example, the Reader dataset might not yet exist when the CityGML reader is used to "Import Feature Types" to the CityGML writer.

Note: This parameter does not override the Additional ADE Schema File(s) parameter.

If selected, only the feature types found in the dataset will be created. Otherwise, all feature types that are found in CityGML core and additional schema files (as specified in Additional ADE Schema File(s) or xsi:schemaLocation) will be created.

Include Generic Attributes as Feature Types: If selected, an extra GenericAttribute feature type will be created to hold all the features created from generic attribute elements (stringAttribute, intAttribute, doubleAttribute and so on).

Include X3DMaterial, ParameterizedTexture and GeoreferencedTexture as Feature Types: If selected, feature types for X3DMaterial, ParameterizedTexture and GeoreferencedTexture elements will be created.

Include Generic Attributes in FME Schema: Regardless of the value specified here, generic attribute will always be read as FME attributes. If this option is selected, those attributes will also show up in FME schema.

Overrides the axis order when reading coordinate tuples in a CityGML <pos> or <posList> element. Valid values are "1,2", "2,1", “1,2,3” and “2,1,3”.

This directive should only be set to YES if the source datasets have texture coordinates and were created by the CityGML writer in FME versions prior to FME 2012. Otherwise, it should be set to NO.

Use this parameter to expose Format Attributes in Workbench when you create a workspace:

• In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
• In a non-dynamic scenario where you have multiple feature types, it is convenient to expose additional attributes using this one parameter. For example, if you have ten feature types and want to expose the same attribute in each one, it is easier to define it once than it is to set each feature type individually in the workspace.

Using the minimum and maximum x and y parameters, define a bounding box that will be used to filter the input features. Only features that intersect with the bounding box are returned.

If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.

When selected, this parameter removes any portions of imported features being read that are outside the Search Envelope.

The example below illustrates the results of the Search Envelope when Clip to Search Envelope is not selected (set to No) and when it is selected (set to Yes).

• No: Any features that cross the search envelope boundary will be read, including the portion that lies outside of the boundary.
• Yes: Any features that cross the search envelope boundary will be clipped at the boundary, and only the portion that lies inside the boundary will be read. The underlying function for the Clip to Search Envelope function is an intersection; however, when Clip to Search Envelope is selected, a clipping operation is also performed in addition to the intersection.

Specify the authentication method to use when accessing a password-protected server.

• Basic: (default) Basic access authentication is designed to allow a client to provide credentials to a server on the assumption that the connection between them is trusted and secure. Note that any credentials passed from client to server can be easily intercepted through an insecure connection.
• Digest: Digest authentication is one of the agreed-upon methods a web server can use to negotiate credentials, such as username or password, with a user's web browser.
• NTLM: A challenge-response protocol that is used to provide compatibility with versions of Windows earlier than the Windows 2000 operating systems.
• Web Connection: Web connections provide a convenient and secure way to store and reuse previously established connection parameters. See Web Connection below.
• Single Sign-on: FME will use the credentials of the current user to authenticate the HTTP request. This authentication method currently works only on the Windows operating system.

Note: To access datasets using a proxy server, use the Network tools in FME Options. From the Workbench menu, select Tools > FME Options > Network. For more information, see "Network Proxy" in the FME Workbench Help.
