= 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 < 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 - {{attachment:sig2.jpg}} - It graphically shows the highest level of error (sigma) is for maplets.
