FME workbench is a powerful tool for translating and transforming data that includes the ability to read data from an Esri Geodatabase.
In this tutorial we will explore a typical approach for creating a basic translation between Geodatabase and any other data format,in this case GML (Geography Markup Language).
The source data set is a Geodatabase - the attached 亚搏国际在线官网communitymap.gdb dataset - containing feature classes.One feature class consists of polygon features representing garbage collection zones:
The other feature class uses point geometry to represent street vendors:
1.Start FME Workbench.On the start page select the Generate Workspace option.This opens a dialog in which to define the translation.
Set the source format as ESRI Geodatabase (File Geodb).For the dataset navigate to,and select,the 亚搏国际在线官网communitymapping.GDB file.
Click on the parameters button.Select GarbageSchedule and FoodVendors in the Table List parameter.Only the tables selected from the table list will be added to the workspace.
Click OK and OK again to return to the Generate Workspace dialog.
2.Set the destination format as GML (Geography Markup Language) and then set a destination folder and filename.Click OK to close the dialog and create the workspace.It will look like this:
3.Click the green run button on the toolbar to run the workspace.
The translation will be carried out and the Geodatabase converted to GML.
4.Inspect the output in the FME data inspector.
As only the data format has changed,the output data set is identical to the source Geodatabase in its structure,or at least as identical as the destination format allows.
Notes
The File Geodb reader used in the example requires a version of ArcGIS installed and licensed.If ArcGIS is not available the File Geodb Open API reader can be used instead.However,please note that this reader/writer does not offer the same level of functionality in all scenarios.For more information please see the following:
