=== Objectives ===
 * First we will generate a maplet with the following parameters:
  * center at -40,135 (lat,lon)
  * scale = 1 km/px
  * size = 99 x 99 px or 99 x 99 km
  * name = ‘LMK000’
 * Then we will tile LMK000 with 9 overlapping better resolution maplets (LMK001-LMK009)

=== LITHOS: Create New Landmark ===
 * ''' LITHOS.e'''
 * '''c''' - create new landmark name
 * '''LMK000''' - landmark name
 * '''l''' - define landmark control point by specifying a latitude and longitude on the body
 * '''-45,135''' - lat, lon
 * '''1,49''' - enter scale (km/px), qsz
 * '''i''' - input landmark
 * '''LMK000''' - landmark name (as previously named)
 * '''y''' - check for images?
 * '''0.5''' - fractional width
 * '''n''' - reject invisibles

 * In a second terminal:
  * cd Vesta
  *ls-Irt
  * display LMRK_Display1.pgm

=== LITHOS: Eliminate Pictures from Landmark ===
 * '''e''' - eliminate pictures from landmark
 * '''a''' - auto-eliminate
 * '''0,40,.2,.2,0,2''' - Input INVLIM,SLIM,CLIM,ILIM,RSMN,RSMX
