Loads (Inputs) a maplet into memory. After entering "i" in the Main Menu it asks for the maplet name. Can also substitute "r" or "RECENT" to load the previously loaded landmark.

Example Break Down:

Check for more images? y[n] - Most times when you load a landmark you will not be adding new images and can say "n" to this question. If you wish to add images see below the line break.

Include a single image? y[n] - Most times you will want to load all images that have been added to the landmark and will use the default "n". If you select "y" it will ask you to input a picture name. This author has never used the "y" option.


If you said "y" to the question "Check for more images? y[n]" you will get this menu

Enter fractional width (0=center). - This asks the user to input the fraction of the image that can be seen in the landmark. Typically we use 0.5.

Reject invisibles? y[n] - This question is referring to whether you want to include images where portions of the landmark will be blocked by some object in the front. For example if most of the loaded landmark is of a crater, but immediately south of the crater is a large boulder, then all images take from the south will have a boulder in the way and this boulder will be obscuring the crater. Typically we will say "n" to include as many images as possible; the image that would have been excluded are usually dealt with once they will no longer align properly.

Typical Use

Most times you will simply want to load a maplet without adding images. In this case you will, from the Main Menu, just use...

i

(Landmark)

n

n


If you do want to add images to the landmark you will enter, from the Main Menu,

i

(Landmark)

y
