Sand Island Lighthouse was successfully scanned using a
new type of device that combines a Light Detection and Ranging (LIDAR)
device with digital images from a high quality digital camera and survey
quality GPS location information - all captured into a computer. The data
we captured is considered high quality engineering data that is accurate
enough from which we can actually build/rebuild things. This scanner is
actually a sophisticated robot like device that draws stares and many
questions when it comes out of its transport case. It reminds me of R2D2.
This is the first and only lighthouse in the world to be scanned with
such a device using the patented "Life Dimensional Technology". Tridex
Solutions Co-Founder/Director Robert Vashisth traveled to Dauphin Island
from UTAH along with his assistant Mark Francis and braved the winter
weather on Dec 6 2008
to meet Jim Hall and Warren Lee of the Alabama Lighthouse
Association at first light at Billy Goat hole boat launch. The Alabama
Marine Police was kind enough to keep a watchful eye on us for safety's
sake. A special thanks to the Alabama Marine Police for this and the many other support functions they
provide to the Sand Island Lighthouse!
Traveling out to the Sand Island lighthouse, we were luck enough to see
an unusual amount of marine life along the way. Several independent dolphins
and pods of dolphins seemed to escort us the entire trip. A kind of mystical
well wishing by them to us or so it seemed. More dolphins were seen going
back to Dauphin Island on our return trip as well. The first of these
dolphins appeared at the very point where we launched the boat and we
continued to see many different dolphins through out our stay at the lighthouse
as well. What a treat for us all!
The imagery we obtained has many uses for the lighthouse but the one
I think you will enjoy the most, is soon we will be building an exact
replica of the lighthouse as a 3D viewable model, which will be accessible
to you using the Internet. This model will at first only have the exterior
visible, but once we obtain the interior data we will add that to the
lighthouse's virtual 3d model and you will be able to view the inside
of the lighthouse as well. This will not be a photo show but a virtual
3D lighthouse that you can inspect from 360 degrees as well as fly up
into the air to see from all angles and elevations.

We will also be creating the most accurate, true scale model of the
Sand Island Lighthouse ever constructed, using this data as well.
Be sure to check back here often and learn where to purchase one of
these models. Just as soon as we have them in hand, I will post the
information on this blog on how to get one. Pretty neat stuff!
We will also use the Tridex data for future engineering when we are
working on repairing the lighthouse and island construction projects.
It will be invaluable for the future monitoring of hurricane damage
The Alabama Lighthouse Association would like to thank the Tridex team
for taking on this difficult task. Visit them at www.tridexsolutions.com
