Not only that, if 2 people talk at once they can cancel each other out and neither can be heard by anyone else.
Much of aviation is still based on pre WWII tech and practices like this and people underestimate how slow and difficult it is to change. Many piston aircraft still run on leaded gas, for example, the last existing market for it in the US.
I got a survey of my residential property, 1/2 acre on a rugged hillside, from a guy who used a drone equipped with lidar. It was $4,000, less than traditional methods, but it would be cool if a drone could just be dispatched from a nearby power pole instead.
Hey, I just did this as well, but with 180 acres of very rugged ravines in rural Kentucky near red river gorge. I only paid $700 though.
My goal was to find all the old logging roads on the property, so I could revive them as hiking and 4x4 trails. This worked excellently as the resolution of the lidar was even better than he quoted and the roads stand out easily (especially after some face coloring based off of slope in blender).
Was your operator a licensed surveyor? Mine was definitely not and (politely) asked me to change my google review to remove any reference to the word "land survey" since he was not licensed to do that.
Yes, this was needed for civil engineering and city permits to replace a retaining wall that holds my driveway up and (hopefully!) keeps it from sliding onto my neighbors fancy expensive house. All licensed and by the book. Quotes from other surveyors were 2x and more.
That's cool to discover entire roads you didn't know about. I would be hoping to discover an ancient city, like they did in central and South America with lidar. Are you sure there aren't any? Look again!
That's super expensive. The majority of those costs are driven by the CapEx of the LiDAR unit. Ours is over $20k. In reality, though, it cost probably <$200 of operating expenses to collect that data.
The solution here is higher utilization of expensive LiDAR. So many pads, and few drones :D
For anything more complex than a shower head, a made in USA label often implies some trickery with final assembly of imported components, like the crossfire example above. Researching the supply chain for every single purchase is too tedious and exhausting for many of us otherwise willing to vote with our wallets.
I learned on here that this has been happening to a degree with maps. Several big companies have been cooperating to improve open street map data, a rare example of a beneficial commons. This is probably some unique accident of incentives and timing and history but maybe it could happen in other domains.
The person who wrote this Spotify p2p software also wrote uTorrent, which was bought by the company bittorrent after they struggled to make a C++ client on their own. The original bittorrent implimentation was in python, but they re-skinned uTorrent as bittorrent and shipped both for a few years.

The name "grapefruit" always seemed a little puzzling when compared with grapes, and it seems nobody is quite sure how the name got started, only that it is from Barbados. One interesting theory is that it is named after the "sea grape", the only kind that grew in that time and place, which has a bitter taste.
