The Layers window lists all datasets, filtered layers, and external datasets.
Most datasets have child layers. A CARIS file, for example, has separate layers for each feature type (polygons, lines, names, soundings, and symbols). Use the expand (+) and collapse (–) icons to show or hide the child layers.
If the box beside a layer name contains a check mark, the layer is visible. If it is empty, the layer is hidden. When you change the visibility of a layer, refresh the display to see the change.
The active layer is the layer on which you can query and select features. Click on a layer name to make it active. The layer name is highlighted. Any layer can be the active layer.
A pop-up menu is displayed when you right-click on a layer name. The layer also becomes the active layer.
• Create Layer: Create a filtered layer.
• Set as Snap/Grab Target: Makes the selected layer the one you will snap to if using the Snap or Grab command.
• Use Coordinate Reference System: Apply the coordinate reference system of one layer to all open layers.
• Zoom to Map: Zoom to the extent of the selected layer.
• Close: Close the selected dataset.
