bigmap

This generates a bigmap from a set of maplets. This can be used to generate shape models or images.

Requires (created)

• LMKFILES/
• LMRKLIST/

• LMRKLIST.TXT - Required. List of landmarks

• MAPFILES/
• SHAPEFILES/

• BIGFILES/ - directory of LMK for each of the required bigmaps - directory must be created, but changes are made within.

• SUMFILES / - info about the maplets

Requires (created & unique)

• BIGLIST.TXT - list of needed mapfiles (bigmaps) used to construct the working bigmap

• INSIDE.TXT - (Created) The maplets that fall completely within the planned bigmap. Created by bigmap

• USED_MAPS - (Crated) All the maps used to create the bigmap.

• Many files must be unique. All directories can be linked to a master.

Optional

• BIGMAP.IN - a list of landmarks that you want to use for bigmap. It allows you to reduce the number of files and avoid low resolution images.

• LMRKLIST.TXT - Same as above, but only used if BIGMAP.IN is missing (used for historical purposes)

• If there are neither of these files, then it will build the list of files that are included in the coverage

Input stdin

• A long set of commands are sent into this program that are usually contained within a file

  Longitude is in west longitude (meaning that you need a negative to match what is used in spheremapB.e

• example:

 ~/bin/bigmap.e < ZN0208.IN

Input file

The format is normally something like this.

l   (select location, 1 is lat/lon)
    20    -40    (latitude, west longitude)
   0.06250       500   1.23400     (scale, qsz (number of pixels), seed) 
ZN0208           (filename)
1                (end or integrate, 1 is integrate)
.005             (input fraction)
.025             (input weight)
1                (end, continue, change weight, smooth, 1 is continue integrating)
1                (end, continue, change weight, smooth, 1 is continue integrating)
1                (end, continue, change weight, smooth, 1 is continue integrating)
0                (end, continue, change weight, smooth, 0 is end iteration)
0                (no, square or round template, 0 is No Template)

Output

• bigmap with the name based on the input (e.g. ZN0208.IN).
• slopeb.pgm image, that shows the slope in both in horizontal and vertical.
• SIGMAS.TXT - Each time BIGMAP is run, it will add a line to this file showing the current sigma values

• SIGMAS.pgm - - It graphically shows the highest level of error (sigma) is for maplets.
