Chapter 8 Display and Level Operations

The edge_maps command is responsible for determining the names of all of the
adjacent maps which currently exist in the default maps_path directory (see
config).  Names of adjacent maps which are found on the active online storage
under the aforementioned directory path are then stored in the header file for
the current, active map.

edge_maps

    Finds/catalogues all adjacent maps in default maps_path directory.
     
         edge_maps [-p]

    Sequentially performs the following three steps:

         1.   Finds all maps in the default map data path which share exactly
              two geodetic corners with the current map.
     
         2.   Checks these maps' header files to see if the current map is
              listed as adjacent.  If it is, then the checked map is added to
              the current map's header file as the reciprocal adjacent map.
     
         3.   Displays on the screen a list of all maps found in step 1,
              flagging those which are in the header file.

    Options/arguments:

    -p        Route the list to the primary default printer, as well as display
              it to the screen.

    Example(s):

    To locate all adjacent maps and update their header files with regard to
    adjacency and display a list of the available adjacent maps to the screen
    and route a copy of the list to the primary printer device, enter:

         edge_maps -p
