Aerial Photographs/Aerial Patrols
As is common in the industry, our electric utility performs regularly
scheduled air patrols. Our aerial contractors are looking for so called "danger trees" that could come in contact with the lines, right of way encroachments, and facility maintenance items. We're using both fixed wing and rotary aircraft. It is a challenge to train contractors and it's labor intensive to investigate each problem. We think a better way of performing this task is to have the contractor provide a digital still image of each item in his report along with the associated geographic coordinate (accuracy is not an issue since anything within 500' is acceptable). I would appreciate any insight, experiences, or comments relative to this topic. Thanks, Mark |

I've been using flexible chemical imaging ribbon for a very long time, and it has many advantages over digital. The key thing is the photograph, not the medium, unless I'm missing something that can be done only if the image is originated digitally. Jose -- Freedom. It seemed like a good idea at the time. for Email, make the obvious change in the address. |

Almost all digital cameras will timestamp their images. Almost all handheld GPSs can produce timestamped tracklogs of where they go. As long as the camera's time is set to the GPS time at the beginning of the day, and suitable track log settings are chosen, you can just use them independently and work out later where you were at the moment a photo was taken. I would recomment a relatively high resolution camera without a long lens. That way the picture will contain a lot of context information to pinpoint the location, but enough information at the center to zoom in and see the problem. -- Ben Jackson http://www.ben.com/ |

Thanks to all for the good advice.
I'm somewhat surprised that there is so little information on the web relative to aircraft camera mounts and remote camera controls. It seems as if the industry is set up strictly for higher altitude acquisition. Incidentally, our fixed wing contractor does employ a trained spotter (his wife). We know this camera idea will be beneficial but finding the hardware is going to be the biggest challenge. If anyone has any experience, knowledge, or insight on equipping the aircraft, please share it. Mark |

You might only need to consider some gyro stabilization for either the camera or that will go on the lens like: http://www.ken-lab.com/html/rafferty_1.html Hope some of this is helpful.

I wasn't aware of any with that functionality built in, but would love to know which ones do. a google of 'digital camera gps stamp' gives further information on methods already described here, and the 'Ricoh 3.24-megapixel Caplio Pro G3' is mentioned in the first hit. I haven't researched further, as I'd lead myself astray. One point to note is that the GPS stamp is that of the camera, not the object, so there would still need to be a means of referencing the two.
