You can switch between the projections North Pole ('N' button), Global View ('G' button), South Pole ('S' button) click on the corresponding buttons in the sidebar.
To switch on and off the available layers, open the 'Map layers' sidebar and use the respective buttons.
On app startup all footprints are loaded which takes a little while where you see a loading symbol with progress bar.
After successful loading you can filter the footprints by 'Mars Year', 'Solar Longitude', 'Incidence Angle' by using the slider controls located at the bottom in the 'Map layers' sidebar.
Now you can select the footprints for which you want to load images into the 'Dynamic layer group' by clicking on them on the map. You can add either intersecting footprints or additionally footprints from other areas. Deselecting footprints can be realized be clicking again on the selected footprint on the map.
For each selected footprint a new image layer is now added to the 'Dynamic layer group'.
Each of these image layers have three controls:
Once added, you can cycle through the selected images by using the 'Play/Pause', 'Forward', 'Backward', 'Stop' buttons which are located in the control bar at the top of the 'Map layers' tab.
To clear the selection use the 'Remove' button on the right of the control bar.
Before or even during cycling through the set of images, you can set the cycle time interval in the input field in the second line of the 'Map layers' tab.
