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:

- Location of bigmap depends on server, try /usr/local/bin as default

 ~/bin/bigmap < 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.
