Examples of Aerial Photos:
The taking and processing
aerial images for our agency customers requires that we imbed the date, time,
latitude, longitude, altitude, direction of photo into
the "meta data" of the photo, then imbed that data on the face of the photo.
Again, these images
not only have this key information on the face of the photograph-- they can be
easily "dropped" on GIS programs like Google Earth or
Because most airborne
photos appear "washed" from haze, we adjust the brightness and contrast of the
photo, then put a Civil Air Patrol "Watermark" in the corner of the photo to
identify that it was taken by the CAP, and place a "N" arrow on the face.
If you are a federal, state or local
agency and have need of high-quality, detailed
(GIS-enabled) images, we we are looking for missions! Please
The photos on the right were
taken by a Gainesville-based CAP aircrew in May 2005 of the F5 tornado that severely damaged
Ringgold, Georgia, at an altitude of 1,000 feet AGL (actual mission photos) as
well as sample photos taken of other infrastructure by CAP aircrews in central

How do I view these images on a map?
We like the
GeoSetter software that automatically maps geotagged images into
Google Maps or Goggle Earth. There are many other options. We
suggest you visit
Geotagging, an excellent Wikipedia article.
How can I view the images full size?
Click on any of the images and a
full-sized geotagged image will load on your browser. You can then view
can view image details.
What equipment was used to take these?
These were taken from the back seat
of Civil Air Patrol Cessna aircraft at 1000 feet above ground level, using
high-resolution (digital) Nikon SLR cameras with specialized GPS, and were
processed using CAP-standard software.
Shutter speeds in most instances are 1000th to a 1500th of a second, which
ensures high resolution.
How long does it take to imbed the geotag?
We have standardized the
Geotagger N2, which sits on top of the Nikon camera and embeds latitude,
longitude, altitude and direction of photograph. The unit
constantly provides GPS information to the camera.
How did you reduce that hazy look we often see in aerial photography?
Using Paint Shop Pro Photo X3.
This software allows us to significantly enhance the contrast and lower the
brightness of each photo; it's "batch" mode allowed us to enhance and
How do you embed the information across the face of the software?
Civil Air Patrol crews use
specialized GPS image processing software; the Georgia Wing uses GPS Photo
Link Express (our primary tool) as well as RoboGeo. These images
were processed with RoboGeo using the "/CAP" setting.
Can I get these kind of results using one of the nicer point and shoot cameras
that has geotagging?
No. The Cessna's high wings block GPS
signal to these cameras; as a result, the geotagging is inaccurate and spotty.
And because they don't have the quality of optics and shutter speed
adjustments of professional cameras, they don't achieve professional results.
We have tried two leading versions, both to poor results.
How hard is this to learn?
Like any new skill, it requires
training and practice. But it's our goal to help ensure that we train
qualified and highly skilled airborne photographers throughout the Georgia
Wing. But we've already learned that anyone with a decent photographic
"eye" can learn the steps.
