Using the Point of View Manager     Updated for Ver. 4.0


Clicking on the POV Icon brings up the Point-of-View Manager dialog box shown below. POV lets you observe the entire lunar surface, by enabling you to obtain a hemispheric view of the moon as seen from anywhere in space.  More precisely, it can be used to change the moon’s hemispherical image so you can center yourself above any location on the lunar surface.


This enables you to view surface features near their centered longitude and latitude so you can see them as they truly appear, unaltered by angle of view factors.  Of course, all of the LMP map tools can be used on any hemisphere being displayed.

Hemisphere Tab


The View Hemisphere Tab has six preset values.  The default hemisphere is referred to as the Central Hemisphere, and is the hemisphere visible to earthbound observers. Clicking Central, precisely centers the map at Latitude 0, Longitude 0.



The opposite hemisphere is referred to as the Rear Hemisphere, which is often called the far side of the moon.  To change the display to one of the other preset hemispheres, simply click the tab displaying the hemisphere of choice, and the map will be redrawn










If the lunar phases are activated, the phase will be accurately displayed for any of the hemispheres.  The following example shows an earth based view, and the associated far side view.




When the view is not directly centered on the central coordinate of a hemisphere, such as when the view is zoomed in near a lunar limb, it may be helpful to refer to the Navigator Window since the drawn rectangle will indicate the portion of the hemisphere being viewed.


Changing the displayed hemisphere has no effect on the section of the disk in view.  For example: if you are viewing the upper right quadrant of the disk, and change the POV, you will still be viewing the upper right quadrant.
