Describe Basic_tiling here.

Basic tiling is how we increase resolution.  This procedure is based on using [[bigmap]].  You can also tile using Lat/Lon [[LatLon_tiling]].

The setup for tiling requires creating an updated [[bigmap]] file and the [[make_scriptT.in]] file.

== Making the bigmap ==

The first step to to make a [[bigmap]].  This provides the basic (and hopefully improved) topography that the new landmarks will be tiled to.  We also use it for the coordinate frame of reference which [[lithos]] will use when building landmarks.

In general, we create an input file that is fed into [[bigmap]] that has the parameters that we want.  An example of this is a file called bigEq4.in that I store in the support directory (it can be whatever name you want).
{{{

You use this set of input values as standard input (stdin) for bigmap as such:

{{{
/usr/local/bin/bigmap < support/bigEq4.in
}}}

[[bigmap]] will run and create a bigmap with the standard MAPLET format.  It will be created in MAPFILES and called EQUAT4.MAP (or whatever 6 character name you gave on line 4 of your input file).  [[bigmap]] will also display the name of the bigmap created.  Additionally, it will add the filename into the file BIGLIST.TXT. 

== Creating the make_scriptT.in file ==

To create the make_scriptT.in file, you must do several things.  In summary, you will be
 * Running [[map_coverage]] to figure out where there are already existing maplets.  It creates [[coverage_m.pgm]].
 * Running [[make_tilefiles]] to get a list of X/Y coordinates for the new maplets.  It reads [[coverage_m.pgm]].
 * Send the output of make_tilefiles to a temporary file and delete the user prompt
 * Create a new make_scriptT.in file that has
  * Coordinate reference system or bigmap name
  * Name of the seed file
  * list of coordinates
  * Keyword "END"
