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, Skencil, and SVG.  Also survexport can produce Compass .plt files,
       which are primarily intended for importing into Carto, but can also be used with Compass itself.

   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.

       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 number part first, 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 EXPORT
       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 configurable.
