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

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

Option 1. Use this when the template you see in LMRK_DISPLAY1.pgm is poor	Option 2 (typical). Use this as much as you can
1 - align landmarks	1 - align landmarks
3 - align with picture	0 - align with template
23 - picture #2 in LMRK_DISPLAY	3 - enter spacing
1 - enter spacing	n - new spacing?
y - new spacing? Yes b/c it only aligned a few images	0 - continue
2 - enter spacing	y - update landmark pixel locations?
y - new spacing? Yes b/c it only aligned a few images	1 - align landmarks
3 - enter spacing	0 - align with template
y - new spacing? Yes b/c 3 caused a couple images to shift>10px	1 - enter spacing
2 - enter spacing	n - new spacing?
n - new spacing? No, lets just use the correlated images first	0 - continue
0 - continue	y - update landmark pixel locations?
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?
# We are skipping V-4 for now. You add this when the model is stable
# v - find V,Z,PTG
# 4 - PTG/SCOBJ from Z and V (current images)
u - update landmark file (save)
1 - save map
