Lesson 2

Objectives

  • First we will generate a maplet with the following parameters:
    • center at 45, 270 (lat,wlon)
    • scale = .00075 km/px
    • size = 99 x 99 px or 99 x 99 km
    • name = ‘TEST01’
  • Then we will tile TEST01 with 9 overlapping better resolution maplets (LMK001-LMK009)

LITHOS: Create New Landmark

  • lithos

  • c - create new landmark name

  • TEST01 - landmark name

  • l - define landmark control point by specifying a latitude and longitude on the body

  • 45 270 - lat, lon

  • .00075,49 - enter scale (km/px), qsz

  • i - input landmark

  • TEST01 - landmark name (as previously named)

  • y - check for images?

  • 0.5 - fractional width

  • n - reject invisibles

In a second terminal: 

  cd Bennu
  ls -lt | head
  display LMRK_Display1.pgm

You can also use the SPC_Tools: landmarks

LITHOS: Eliminate Pictures from Landmark

  • e - eliminate pictures from landmark

  • n - auto-eliminate new images only (a for auto-eleiminate)

  • 0,50,.2,.2,0,4 - Input INVLIM,SLIM,CLIM,ILIM,RSMN,RSMX

lesson2_EliminatePicsFromLandmark.jpg

lesson2_EliminatePicsFromLandmark2.jpg

  • INVLIM = 1000 * MAX INVISIBLE FRACTION (0-1000)
  • SLIM = MAX EMISSION ANGLE (0-90)
  • CLIM = MIN FRACTION OF VISIBLE (0-1)
  • ILIM = MIN FRACTION IN SHADOW (0-1)
  • RSMN = MIN IMGSCALE/MAPSCALE (0-inf)

  • RSMX = MAX IMGSCALE/MAPSCALE (0-inf) =>set according to printout and LMRK_DISPLAY

  • Most permissible: 1000,90,0,0,0,inf => does not throw any image away

  • Least permissible: 0,0,1,1,inf,0 => throws all away

  • display LMRK_DISPLAY1.pgm

LITHOS: Get Heights from Shape and Find Normal, V

  • m - get heights from shape model

  • n - find normal

  • 2 - normal from heights

  • m - get heights from shape model

  • u - update landmark file (save)

  • 1 - save map

In 2nd terminal: 

  cd Bennu
  ls -lt | head
  display LMRK_Display1.pgm
  more LMRKLIST.TXT
  more LMKFILES/TEST01.LMK
  more MAPFILES/TEST01.MAP
  showmap 
      TEST01

Then display the TEST01.pgm (xv, imageMagick, convert, GraphicConverter)
