dump3d - text dump of processed survey data file

       1998-2025

                                                  Feb 21, 2025                                         DUMP3D(1)

       Dump  out the entries in a processed survey data file - useful for debugging, and also provides a textual
       format which is fairly easy to parse if you want to write a simple script to pull  out  information  from
       such files.

       Don't  be mislead by the "3d" in this tool's name - it can be used to dump a file in any format the "img"
       library can read, so it works with Survex .3d and .pos files, Compass .plt and  .plf  files,  CMAP  .sht,
       .adj and .una files.

       If you're parsing the output in a script, you may want to use option -legs so you get a LEG item for each
       leg  with from and to coordinates instead of each traverse being a MOVE item followed by a series of LINE
       items.

       The --show-dates option uses . as the separator between date components by default (e.g. 2024.12.01), but
       (since Survex 1.4.13) you can specify a different separator.  If this separator  is  .  then  -  is  used
       between  two  dates  which form a range, otherwise a space is used.  For convenience, -D is provided as a
       short-cut for --show-dates=- which outputs dates in the ISO date format.

       (The --rewind option is only provided to allow debugging and testing the img_rewind() function.)

-s,--survey=SURVEY
              only load the sub-survey with this prefix

       -r,--rewind
              rewind file and read it a second time

       -d,--show-dates[=SEPARATOR]
              show survey date information (if present)

       -D     equivalent to --show-dates=-

       -l,--legs
              convert MOVE and LINE into LEG

       --help display short help and exit

       --version
              output version information and exit
