Vector Longitudinal Survey Setup
There are a set of
instructions listed directly in
the Vector Longitudinal
Tunnel Survey at the bottom
of the menu. Please follow
these instruction. A review
of these instructions is also
shown in the following
powerpoint slides
Step 1. Create a Y
survey information
file with the y
start/end.
Step 2. Create a the
vector files with the
vector radio button
and the nav file
checked on.
Step 3. Convert,
Navigation using
Artificial Marker,
Slice/Resample or do
Radargram Signal
Processing as
desired….etc
Step 4. Set the
longtudinal angle for
each radargram by
hand in the Vector
Longitudinal Tunnel
Warping menu. Set
the tunnel radius as
well. Click the Vector
Longitudinal Tunnel
Survey button to
generate the
longitudinal vector
files.
Step 5. Open the
Open GL 3D Vector
Radar menu to
display your
radargrams along the
longitudinal tunnel.
The x0, x1, y0, y1 can
be reset to your
desired length to
show radargrams.
Option- Variable length tunnel radargrams
Step 1. If you need
to adjust the start
and end length
Then go back and
just make
information file with
just y survey
Option- Variable length tunnel radargrams
Step 2. Adjust the y0
and y1 for the
radargrams. In this
example the first 2
radargrams have
their start and end y
values adjusted.
Option- Variable length tunnel radargrams
Step 3. After
adjusting the y0 and y1
for the radargrams,
click the ANG, X, Y, XY
to Vector button to
generate the vector
files. (Note, the y1
colume will change as
this column now stores
the number of
GPS/Vector navigation
points)
After this, continue
with Navigation,
Artificial Marker,
Slice/Resample
operations.
Step 4. Generate the
Vector Normals.
Step 5. Display the
Open GL Vector 3D
Radar data. Here the
different radargram
start/end points can be
seen.
