Lesson 2

Objectives

First we will generate a maplet with the following parameters:
- center at -10, 10 (lat,wlon)
- scale = .001 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.e
c - create new landmark name
TEST01 - landmark name
l - define landmark control point by specifying a latitude and longitude on the body
-10,10 - lat, lon
1,49 - 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
a - auto-eliminate
0,40,.2,.2,0,2 - Input INVLIM,SLIM,CLIM,ILIM,RSMN,RSMX

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)

LITHOS: Align Landmarks in Pictures

1 - align landmarks
3 - align with picture
23 - picture #2 in LMRK_DISPLAY
1 - enter spacing
y - new spacing? Yes b/c it only aligned a few images
2 - enter spacing
y - new spacing? Yes b/c it only aligned a few images
3 - enter spacing
y - new spacing? Yes b/c 3 caused a couple images to shift>10px
2 - enter spacing
n - new spacing? No, lets just use the correlated images first
0 - continue
y - update landmark pixel locations?
1 - align landmarks
3 - align with picture
1 - picture #2 from last iteration became picture #1
1 - enter spacing
n - new spacing?
0 - continue
y - update landmark pixel locations?
display LMRK_Display1.pgm

LITHOS: Find Template

u - update landmark file (save)
1 - Save map
0 - find template
c - use correlated
.7 - enter correlation limit
0 - find template
0 - continue
40 - number of iterations
display LMRK_Display.pgm

LITHOS: Align Landmarks and Find Template

1 - align landmarks
0 - auto align
1 - enter spacing
y - new spacing?
2 - enter spacing
n - new spacing?
0 - continue
y - update landmark pixel locations?
1 - align landmarks
0 - auto align
1 - enter spacing
n - new spacing?
0 - continue
y - update landmark pixel locations?
display LMRK_Display1.pgm
0 - find template
c - use correlated
.7 - enter correlation limit
0 - find template
0 - continue
40 - number of iterations
display LMRK_DISPLAY1.pgm
REPEAT ONCE

LITHOS: Solve for Heights

2 - find heights
8 - fill with shape
2 - include existing heights
.01 - input fraction of points
1 - auto include neighboring maps
#4 - include limb vectors
#1,2.5,3 - input expansion, res/scale limit, d_hgt limit
6 - include differential stereo
y - use gradients?
y - autoheights?
0 - begin iteration
.025 - input weight
30 - enter number of iterations
0 - end iterations
display LMRK_DISPLAY1.pgm
display slope.pgm

LITHOS: Final Alignment and Save

1 - align landmarks
0 - auto align
1 - enter spacing
n - new spacing?
0 - continue
y - update landmark pixel locations?
v - find V,Z,PTG
4 - PTG/SCOBJ from Z and V (current images)
u - update landmark file (save)
1 - save map
