Advanced/Custom Maps

From JMARS Wiki

The Advanced Maps Layer allows users to load custom-made maps into their local copy of JMARS. Once loaded, these maps can be used in conjunction with other JMARS layers (ie: Stamp Layer, ROI Layer, etc) or on their own.

[edit] Load a Custom Map into JMARS

Open the Advanced Map Layer: Chose "Add New Layer" -> "Advanced Map"
Upload a Map: In the "Available Maps" section of the pop-up box, click "Upload Map".

In the "Upload File" pop-up box, users can either:

Specify the file path or URL to an existing map, formatted as an ISIS cube.
Specify the file path or URL to an existing image file (PNG, JPEG, etc), as well as latitude (N & S) and longitude (W & E) bounds. An ignore value can also be set, which will specify which color in a gray-scale map should be transparent. (Almost always set to 0, when used.)

When the upload is complete, an icon with the title of the advanced map should appear under "Mars Space Flight Facility Custom Mapserver" in the Available Maps section.
If not, double click on the "Mars Space Flight Facility Custom MapServer" option in the "Available Maps" section to see all advanced maps you have uploaded.

Load the Map into JMARS: Left-click on the name of the advanced map you want to display, drag it into the "Visible Map" section and drop it on top of the word "Input". Click "Ok" to view the map in JMARS.

[edit] Edit the Custom Map Settings

Open the Configuration Window: In the Layer Manager, click on the tab named after the custom map, then click on the "Configuration" button at the bottom. The Custom Maps Settings window will appear.

Adjust Map Position: If the custom map did not load in the correct position, but is relatively close to it, click on the tab named after the custom map in the Layer Manager, then click on the "Input" button. Use the arrows to adjust the map's position.

The number in the center of the arrows is the number of pixels that the map will be moved for each arrow click. It can be changed to either 1,2,5 or 10 by clicking on the number.
The "Reset" button will return the custom map to its original position.

[edit] Graph Values from Multiple Numeric Maps

Open a Numeric Map: Open a numeric map using either the Numeric Map Layer or the Advanced Map Layer

Open the Configuration Window: In the Layer Manager, click on the tab named after the first numeric map, then click on the "Configuration" button at the bottom. The Custom Maps Settings window will appear.

The name of the first numeric map will appear in the "Plot" section.

Plot Values from Another Numeric Map: Under the "Source Maps" section, select another numeric map. Left-click, hold and drag the numeric map name into the "Plot" section.

Numeric maps are indicated by an icon with a "01" icon.

View a Graph of the Numeric Data: Draw a profile line in the Viewing Window and the numeric values from both graphs will be plotted in the focus panel.

[edit] Creating Contour Maps

Open the MOLA Numeric Map: In the Layer Manager, choose Add New Layer -> Advanced Maps. In the "Availble Maps Window" under "Mars Space Flight Facility MapServer", choose "By Instrument" -> "MOLA" and then drag "Mola_Elevation_Topo" to the "Visible Map" section and click "OK".

The Mola_Elevation_Topo amp should have a "01" icon next to it, indicating it is a numeric map.

Create a Contour Map: In the Layer Manager, click on the Mola_Elevation_Topo tab. In the focus panel, click on the "Input" tab. On the "Input" screen, click on the "+" button in the "Greyscale" section and choose "Contour" from the drop-down menu.

A contour map will be created with the default values. Editing the values in the next "Contour" section will re-draw the contour map with the new specifications.
