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
TEST01Then display the TEST01.pgm (xv, imageMagick, convert, GraphicConverter)
