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
