NAME

       survexport - convert a processed survey data file to another format

SYNOPSIS

          survexport [OPTIONS] INPUT_FILE [OUTPUT_FILE]

DESCRIPTION

       The  input  formats supports are all those supported by Survex's "img" library - Survex .3d, Survex .pos,
       Compass PLT and CMAP XYZ files.

       Currently the output formats supported are  CSV,  DXF,  EPS  (Encapsulated  PostScript),  GPX,  HPGL  for
       plotters, JSON, KML, Survex POS files, and SVG.

       Also  survexport  can produce Compass .plt files, which were primarily intended for importing into Carto;
       the principal author of Carto has sadly died and it seems Carto is  no  longer  actively  developed,  but
       we've  left  this  support  in  place in case it is useful - the generated files can be used with Compass
       itself for example, though they are rather crudely structured.

   POS Format
       The POS format is a Survex-specific format containing a list of stations with coordinates (ordered  x,y,z
       [East,  North,  Up])  and complete names.  In old versions of Survex it was produced by the (now removed)
       3dtopos tool.  Since Survex 1.2.19 it can be generated by survexport or by aven's export feature.

       The header line is translated to the user's language, but always starts with ( and ends with ).

       While not a requirement of the format, in .pos files created by Survex the stations are  sorted  by  name
       such  that  numbers occur in the correct order (so 2 before 10).  Numbers with a prefix and/or suffix are
       sorted by the prefix as a string, then the number part as above, then by the suffix as a string, so you'd
       get:

          040.sv8
          040.sv8a
          040.sv8b
          040.sv8c
          040.sv9
          040.sv10
          040.sv11
          40_entrance_tag
          40b_entrance_tag

   DXF Format
       DXF export separates Splays, Surface legs, Surface points, survey legs, and survey stations onto separate
       layers.  Splays will export dotted, and surface legs dashed.  This is not currently configurable.
