[Aztlan] Fw: Aerial survey

[donald raab]

Dave,
 
 1/4" Sony Super HAD CCD 
- 380 horizontal lines of resolution.
- Sensitivity: 1.0Lux / F2.0

The camera is mounted to look straight down.  The GPS coordinates and altitude are displayed real time as an overlay.  The GPS unit uses 12 satellites for tracking and is accurate to 1 meter.  The camera angle can be changed manually to look down at an oblique angle of 25 degees from the vertical.  
 
The aircraft flies in a speed range of 25-45 mph with power and less in glide mode. It's most effective altitude is 100-300 feet.
 
To your second question I do not have sample clips on line.
 
Thanks,
 
Don Raab

My first question would be, what is the resolution of the video camera?
Second, are there any clips from Caracol online where members of the
list could see them and evaluate how this could be useful?

> Recently I retired from Northrup Grumman.  For many years I have been an amateur archaeologist specifically interested in Meso and South America.  I've also enjoyed a lifelong hobby.  That is building and flying radio control model aircraft.  A few years ago I developed an RC electric powered glider.  I installed in it a live TV system.  I used my first version to prove the concept flying  at the Caracol site with the BVAR field school.  Since then I have a new version that has added GPS overlay capability.  As the real time video is captured it is ovelaid with GPS coordinates and altitude.  A survey mission would involve flying a selected area (one mile square) like a lawnmower.  The live video is captured via a minature DVR via a scan chip.  It could also be inputed directly into a VCR or computer.  the chip also can be downloaded into a computer.  Using something like Windows movie maker all sorts of slice and dicing can be
 accomplished.

Any reasonable cleared area near the survey site can serve as the launch and recovery area.  I used the center quadrangle opposite the main pyramid in Caracol as the launch area.
