Background Challenges AIR FORCE SPECIAL

AFSOC uses images such as this
one to support the wars in Iraq
and Afghanistan. With LizardTech
Express Suite, AFSOC can encode
this high resolution image to JPEG
2000 at a 10:1 compression ratio,
store it in an Oracle database and
serve it out via ArcIMS.

off the Runway Four Times Faster
Recently, the Air Force Special Operations Command
(AFSOC) had a need to compress and reproject over 3
terabytes of imagery to the MrSID® and JPEG 2000 format,
and to store data as Oracle GeoRaster objects. This
imagery would be used to directly support U.S. warfighters
in Iraq and Afghanistan. AFSOC already had a workflow
pulling imagery from a repository and serving it via ArcIMS.
AFSOC came to Smartronix of California, MD (http:// for a solution.

3 TB of raw image data
Initially AFSOC had estimated just over three months (45 minutes per 1GB)
to complete the project with its existing configuration. “This estimate was
based on past performance experience and testing,” says David Streed,
senior geospatial engineer for Smartronix. “But three months was too long to
wait for this imagery to be deployed; AFSOC needed to be able to distribute
this imagery within weeks. AFSOC wanted to switch to an Oracle database
for storage and serve imagery via Oracle MapViewer, but also needed to
keep the original workflow in place while the new one was implemented.
Ideally, this would mean finding a way to serve imagery via both ArcIMS
and MapViewer. We also had to identify bad images (and we had a few out
of the thousands of images we processed). Finally, we had to convince the
customer to go with a new product that promised to integrate existing and
new technologies.” | 1.866.725.5211 or 206.652.5211 |
Smartronix chose to go with Express
Suite® software from LizardTech®.
Smartronix ended up using
GeoExpress® software to reproject,
compress and create MrSID or JPEG
2000 imagery, the Spatial Express®
extension to Oracle Spatial to store
the wavelet compressed images in
an Oracle database for distribution
via MapViewer, and Express Server®
image serving software to distribute the
imagery via ESRI’s ArcIMS. “Completing
the work in the required time with
minimal staff required us to run Spatial
Express 24/7 for 2 weeks,” says Streed,
“and it was a very reliable tool.”
LizardTech’s command line tools helped
with the task of identifying bad images.
With this new configuration the project
was completed in just three weeks. This
included compressing the entire 3TB
of imagery, reprojecting a portion of it,
and loading it into the database. That’s
4.5 times faster than the initial estimate,
saving AFSOC over 1,700 man hours
and providing its users with the imagery
they needed quickly.
“Our requirements for storage dropped
from terabytes to gigabytes, keeping
AFSOC’s equipment costs down and
giving them a smaller footprint.”

AFSOC realized the following benefits using LizardTech’s
ExpressSuite software:
• Mission accomplished – Imagery moved to Oracle database and
available via MapViewer
• Reduced storage requirements – 3 TB of imagery reduced in file size to
190 GB
• Time and labor savings – Project completed 4.5 times faster; 1700 man
hours saved
• Reduced software costs – No need to maintain products of earlier
