Map Engines Tool

The Map Engines Tool lists the registered Map Engines sources. If you click on an item from the Map Engine list in the left panel, the list of layers in that Map Engine will be displayed in the right panel. The Map Engine tab on the bottom of the window gives you details of that engine; the Layer tab gives you details about the Map Layer that’s highlighted in the top right panel. 

This tool also has a Reset button (only available in 2.5.26). This tells Weave to clear any cached information it may have on a back-end map service and is useful when you change the service and need Weave to take note of the update.
