In the screenshot (right), a 50 foot x 50
foot area was surveyed in one direction
only with profiles spaced every 2 feet.
This survey created 26 DZT and DZX
files (1 every 2 feet including the line at
0) and 1 BZX file. The Grid was named
GRID__003.3DS. The grid name was
automatically generated by the SIR 4000
within the project folder,
COMMON.PRJ.
•
The BZX file is an information file
which tells the RADAN software where
each DZT file is positioned and directs
the software to create a 3D file with the
proper positioning information. Opening
the grid in RADAN is as simple as
opening the BZX file.
•
The project folder will also contain a subfolder
called Proc. This folder contains DZP files that
are used to playback the 3D data on the SIR 4000.
They are not necessary for 3D viewing or processing in RADAN.
•
When transferring data from the SIR 4000 to a PC running RADAN, the entire Grid folder is
transferred. In order for the BZX file to work all of the DZT and DZX files must be kept in the same
folder as the BZX file.
In summary: each grid is saved in a separate folder under the project folder. Inside each folder are all of
the individual radar profiles (DZT and DZX files) and one BZX file. The BZX file tells RADAN where to
put each profile to create a 3D grid.
7.2: Setting Up a Physical 3D Grid
Collecting data for 3D processing and interpretation is easiest
when following a physical guide grid. Grids can be laid out
using chalk, paint, measuring tapes, ropes, or some other
method. A grid can be any size, but data quality is better if the
grid corners are square. The grid itself does not have to be a
square, it can be a rectangle, or can be irregularly shaped.
Follow the tips below to help ensure successful grid setup and
data collection.
The graphic below illustrates how to put together a square,
10×10 grid. You can use the following method to setup grids
of any size including rectangular grids. Make sure to assign the X and Y axis.
Note
: You must keep the BZX file and all
associated data files together in the same
grid folder.
