Layer Window

Layer Window

This creates a docked window on the left of the Viewer window containing the list of layers loaded in order of display. This window can be dragged off from being docked and be a separate window. Double click the title bar to re-dock.

Each layer has a tick box next to it. You can turn the display of individual layers on and off using this.

If you right click on a layer, a menu is displayed with options relating to that layer. Some options are common to all layer types:

Zoom to Layer Extent

Changes the zoom of the Viewer to be the extent of this layer

Remove Layer(s)

Removes one of more layers from the Viewer. The layers that are selected will be removed.

Move Up

Moves the layer 'up' in the rendering order - it is painted later and so is 'higher'.

Move Down

Moves the layer 'down' in the rendering order - it is painted earlier and so is 'lower'.

Move to Top
