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.
