The ArcGIS Interoperablitiy Extension Inspector is a quick way to view data at any point while it is being manipulated in Workbench.
There are two ways to add an Inspector:
Note: You cannot start the Inspector by clicking on the fmeview.exe file in your installation folder.
The Inspector transformer is located in the Workbench Transformer Gallery, in the Infrastructure category.
There are several options that you can change. Click the Properties button to display the Properties dialog.
Transformer Name: Changes the name that is displayed on the bottom of the transformer, as well as the root name of the data in the Inspector.
Note: An easy way to insert an Inspector is to right-click an output port on a transformer, and choose Connect Inspector. This will automatically give the Inspector the same name as the output port.
Attributes to Group By: Groups attributes and treats each group as a separate output in the Inspector.
Pen Color Override: Forces all attributes to be displayed with the selected color.
Area Fill Color Override: Changes the fill colors of all attributes connected to the transformer.
This will open an Inspector with a view of the data at the final stage of processing. Essentially, what you see in the Inspector should be very close to the final dataset.
You can further customize the dataset view from within the Inspector.
