Background Maps (Workbench)

You can overlay data that displays in the Visual Preview onto a background map, which allows you to view your data in context.

For example, if you have a dataset that contains roads in a specific city, you can overlay this data1 Background Maps: ArcGIS Online: Sources: Esri, DeLorme, NAVTEQ, USGS, Intermap, iPC, NRCAN, Esri Japan, META, Esri China (Hong Kong), Esri (Thailand), TomTom, 2013 MapQuest: Tiles Courtesy of MapQuest Stamen: Map tiles by Stamen Design, under CC BY 3.0. Data by OpenStreetMap, under CC BY SA. onto a background map of the same area:

When you apply a background map, both the dataset you open and the background map dataset appear together in the View window and the Display Control.

Only features of the dataset you open can be selected for viewing in the Feature Information window or Table View. You cannot zoom in or otherwise change the view of the background map: the focus is always on your own data.

Note: Background map data is reprojected to one of the coordinate systems referenced by the dataset(s) that comprise your view. If you want to reference the coordinate system of the background map when viewing coordinates in the Status Bar, use the drop-down list to select it. For more information, see Changing Coordinate Systems in the Status Bar.

Getting Started with Background Maps

In the Background Maps window under FME Options, you can create and remove background maps. In most cases, however, it is more convenient to create and manage background maps directly in the Visual Preview.

Using Background Maps in the Visual Preview

Do one of the following:
- If you have not previously added any background maps, right-click on the View node in the Display Control and select Add a background map.
- If you have previously added background maps, right-click on the background map in the Display Control and select Switch to new background map.
The Add Background Map dialog opens.
Source: Select the background map you want to apply to the view.
Name: Give the background map a name. Data Inspector saves the background map and all of its settings with this name, so you can reuse it in future views.
Apply the remaining settings, depending on the Source. For more information, see Background Map Source Settings, below.
Click Save. The background map appears in the View window and Display Control.

To Add and Use More Background Maps

Right-click on the background map in the Display Control and select Switch to new background map.

To Switch to a Background Map You've Already Created

Right-click on the background map in the Display Control and select it from the context menu.

To Turn Off a Background Map

Right-click on the background map in the Display Control and select Background map off.

To Add, Edit, Duplicate, or Remove Background Maps

Right-click on the background map in the Display Control and select Manage background maps. In the FME Options Background Maps pane, right-click on a background map name and select Edit, Duplicate, or Remove as desired. You can also remove a background map with the (-) button. To add a background map, use the (+) button.
