Using FORENSIC MAPPING SYSTEM techniques
to enhance FIRE SCIENCE skills
with VistaFX!
A critically
important component of any major Fire Investigation conducted by
Public Safety agencies, is to document witnessed events,
locations of egress and ingress of structures, burn patterns &
ignition locations, mass victim locations, and other facts.
The on-scene
trained Fire Investigator, among other duties, measures and
records, when possible, certain relevant findings and evidence
as noted above. In recent years, the use of ‘reflectorless’
electronic Total Stations, a Windows-based data collection
platform, and software possessing advanced 3D animation
capabilities (all components of a Forensic Mapping System) has
emerged as a viable tool in the Science of Fire Scene Analysis,
Interpretation, and training.

As seen above,
a ‘reflectorless’ Sokkia brand Total Station and TDS Recon
EvidenceRecorder(EvR) is being used to practice for the
inevitable use of this modern technology.
Public Safety
officers / fire fighters are trained in its highly specialized,
topic specific, narrowly focused 40-hour training class.

The Sokkia ‘reflectorless’ Total Station (model LEA530r3) has
an additional feature that has proven invaluable and
perfectly compllments the already existing ‘reflectorless’
capability. And that is the “red-aiming dot” that is aligned
from the manufacturer, with the Instruments aiming
“cross-hair”. This allows the investigator to view, as seen
here [ ], where the Instrument is exactly pointed without
having to otherwise look through the ‘reticle’ and focus on the
evidence item. Under certain light conditions, as well as close
proximity to the object itself, this other wise would be nearly
impossible ~ but for the ‘red-aiming’ dot.
A ‘red dot’ is
also illuminated on the Instrument itself, to remind the User
that this useful feature is in the ON position.
Once the scene
has been documented, it is then possible to return to your desk
and create a to-scaled room or structure for further Scene
analysis.
In as much as
in today’s world, we are, as a whole, a VISUAL society … the use
of 3D models, to the caliber constructed by the Structural
Design experts at the FBI, and/or ‘live’ reconstructed 3D
animation have proven a valuable tool for the Fire
Investigator/Scientist. Research has shown over the past couple
years, that 8 of 10 jurors want to “see how events occurred”,
based on an investigators physical evidence and other facts
found at the scene.
Shown below left, is an innovative,
VistaFX
generated 2D model from scene measurements. To give some idea
of the rooms size, a 1 ft. grid is seen:

Note the
inclusion of TRANSPARENT walls (2-sides) and the presence
of “explosive”, and growing (‘shooting’) FLAMES!
The over head
view takes on an entirely different and accurate, given facts,
perspective once viewed in 3D.
Where
appropriate, the inclusion of transparent walls for example,
could aid in a more professional presentation before the court
or Jury, visibly illustrating how certain aspects of the event
were known to transpire.
The effect of virtual “moving” flames is
an EXCLUSIVE of VisaFX.
It could aid the Prosecution during Discovery proceedings, or
serve to help with Advanced in-house training scenarios.
More topics concerning the Fire Sciences as they relate
to the application of the Forensic Mapping System
will be covered here. |
