Process for creating a custom GML format
You may have the need to use GML profiles other than those that match the existing GML profiles directly supported in ArcGIS and the Data Interoperability Extension. For example, many local organizations provide their content in a specialized GML profile that has been adopted by the local community.
The mechanism to do this in ArcGIS is to create a custom format using the Data Interoperability Extension for ArcGIS Desktop. Here is the process for creating a custom GML format.
First prepare your system by ensuring the following:
- You have installed and enabled the Data Interoperability Extension in ArcGIS Desktop.
- You have a GML file on your system in the format of the custom GML profile.
Once you have these in place and enabled, perform the following steps:
- In ArcCatalog, add a new interoperability connection by double-clicking on "Add interoperability connection."
- Click the button for Format to open the Formats Gallery.
- Add a custom format by selecting "New."
This will open the "Create custom format" wizard that will lead you through the process of creating a custom data format for use in ArcGIS.
- You will be asked to select the format of your data source. Choose the "GML - Geography Markup Language" format.
- You will be asked to enter a file containing the source data. Specify your GML file.
- The software will identify the supported elements contained in your file and ask you to identify which ones you want to use as well as to give a name and a description of your custom format.
- When you complete the steps in the wizard, the FME workbench application will be started for your GML data and a simple GML convertor. This environment enables you to add other files (such as an attribute table) and to perform any translation and conversion operations you need in order to effectively transform and use your GML data source.
