survexport - convert a processed survey data file to another format

survexport [OPTIONS] INPUT_FILE [OUTPUT_FILE]


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.

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 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.
