Layer Manager
From JMARS Wiki
The Layer Manager displays the open layers in the order which they are “stacked” in the Viewing Window. The Layer Manager opens in its own window so that users can view both windows at the same time and can adjust its size relative to the Viewing Window. The Mola Shaded Relief Map (64ppd) and the Latitude/Longitude Grid layers are the default layers when JMARS is opened.
- To Add a Layer: Click on the "Add New Layer" button, which will give you a directory of available layers. (Each of these layers is described later in the wiki.)
- To Remove a Layer: The user can either highlight a layer and click the "Delete Layer" button or, to simply prevent JMARS fropm displaying the layer, click on either the "M" or "P" buttons to the left of the layer name. This will remove the layer from either the Main View or the Panner View, respectively.
- To Adjust the Transparency of a Layer: Use the slide bar to the right of the layer name. By default, each layer is set to zero transparency, but can be adjusted to the user's preference.
- To Undock a Layer: In some cases it is useful to separate a layer's focus panel from the rest of the Layer Manager. This allows it to be displayed in a separate window while the Layer Manager can continue to be used as normal. To separate a layer, left-click on a layer's tab and drag the tab outside of the Layer Manager window. To return the focus panel to the Layer Manager, just click on the "X" at the top-right of the window.
The various parameters associated with each layer can be changed by clicking on the appropriate tab at the top of the Layer Manager. The various options available for each layer are discussed in the layer description pages.
In order for some layers to function in the Viewing Window, such as the THEMIS Planning layer, they must be selected as the "active" layer in the Layer Manager. This is done by left-clicking on the layer name and is confirmed by a blue outline. The functions that this enables for each layer are also discussed in the layer description pages.
Some JMARS layers require a large amount of data in order to function, which means it can take a very long time for JMARS to load the layer in the Viewing Window. The status of each newly added or edited layer is given by the Drawing Status buttons. Green indicates the layer is fully drawn, Yellow indicates that the layer is being drawn and Red indicates the layer is still retrieving data from the database.
