I survey our power grids for a living. This includes photogrammetry coverage as well as LiDAR. It's a great job, I enjoy doing it and it affords me the opportunity to travel the country. I get to see sights I would never think to visit on my own accord, meet great people and photograph electric poles. Ok, last part isn't to exciting but the rig I use is - 8 Nikon D-850's each with Zeiss 25mm 2.8 Distagon lenses. The rig provides 360 degree coverage of the environment traversed. On a typical day I collect 1 to 2 terabytes of photographic images. Currently upgrading the system to 10 Nikon Z-7's with Zeiss 25mm lenses. Should be hitting the road later in the week.
