Adding new GML application schemas
Community-specific GML application schemas are specialized extensions of GML created by local organizations. They are used to support data interoperability within a community of interest—enabling users to refer to features with agreed-on names such as roads, highways, and bridges instead of as points, lines, and polygons. If a particular GML application schema is not supported out of the box, you can add it to ArcGIS by creating a custom format.
To create a custom format, you must install the Data Interoperability extension, then purchase a license and enable the extension in the desktop application. After enabling the extension, you can create a preliminary translation using the standard GML reader and a dataset on your system that is already in the community-specific schema. Then use FME Workbench to modify the translation to meet your specific schema requirements.
The following steps describe how to add a custom GML format to ArcGIS. The custom format is saved as an external .fds file and added to FME Reader Gallery. Subsequent use of the gallery includes the custom format as a selectable option.
Steps
- In the Catalog window, expand the Interoperability Connections folder.
- Double-click Add Interoperability Connection.
- Click the Format browse (ellipsis) button to open FME Reader Gallery.
- Click New to open Create Custom Format Wizard.
- Click Next.
- Click the browse (ellipsis) button and choose GML (Geography Markup Language) for the source format.
- Click Next.
- Click the browse (ellipsis) button and choose the dataset on your system that is already in the new GML schema.
- Click Next.
- Check the check boxes for any parameters you want to specify each time you use the custom format.
- Click Next.
- Type a name and description for your custom GML format.
- Click Next.
- FME Workbench opens a (.fds) workspace with a model of the information you provided. Modify the workspace so that it performs any translation and conversion operations necessary to transform and use your GML data source.
- On the FME Workbench main menu, click File > Save to save your .fds workspace as a custom format.
