2.B Tunnel file syntax
Tunnel writes all the survey and sketch data in XML format.
The XML syntax of Tunnel is rather straightforward.
All Tunnel XML files start with the tag <tunnelxml> and ends with the corresponding closing tag.
2.B.1 Survey data files
Tunnel survey data files contains the same information as survex data files,
albeit with some difference in the organization.
Survey data file starts with the object measurements
(attribute
name
, the name of the survey). This contains
objects set
(used to define an attribute of all the enclosed objects),
and leg
(similar, but the name is different for readability).
Objects leg
contains the objects that make the actual shot,
for example tape
, compass
and clino
(each with attribute
its value fval
).
The export files are used to join together the surveys.
They start with the object exports
which contains the
object export
which has the attributes estation
, the name
of the station in this survey, and ustation
, the name when
referred from other files.

2.B.2 Sketch files
The object
sketch
has attributes
splined
: can have value 0 or 1
and contains the objects
affinetrans
,
skpath
, ...
TODO continue.
The object affinetrans
is used to define the included background image.
It has attributes for the coefficients of the affine transformation
of the background image, and contains the object backimage
which
has attributes the image filename imgfile
and selected
(values
0 or 1).
The object skpath
has attributes the linestyle
, and the
node indices from
and to
.
It contains two or more node objects pt
with attributes X
Y
and Z
. The attribute Z
may be missing.
A centerline contains the object pathcodes
containing the objects
cl_stations
(with attributes tail
and head
).
A connective path can contain the object pathcodes
containing the
one of the objects pcarea
(with attribute area_signal
),
pcsymbol
(with attribute rname
),
pctext
(with attributes style
, nodeposxrel
and
nodeposyrel
). Objects pcsymbol
can be repeated.
TODO continue.
The data that Tunnel will write in the sketch file can be seen in the
drawing window in the "info" tab. For example open a survey and
open the "Info" tab. Select a path and you can read the path XML data
in the tab.
