Lightroom is likely more than you need, but Lightroom does this.
I convert my various (nef, cr2) raw files to DNG upon importation to my library, and save metadata to the files themselves, not XML sidecar files.

While Adobe Lightroom will want work with its own database, by always syncing metadata to file you will have a 100% portable set of images.

They filter the signal by putting a shield of radio-absorbing material under the antenna itself. Unlike your phone, hand held, or removable car one, the orientation of the receiver is a given and such techniques can be employed.

Non-survey grade GPS positioning is a code-based lock, not carrier, so there is no phase correlation that I am aware of.

Not all differential signals are ground based, the geo-sync WAAS satellites are the most common free source of differential signals (outside mobile phone applications)(at lest in the west, and there is no common terrestrial differential correction elsewhere in the world), while there are also many commercial differential sources, most all are based upon satellite relays.

As to your worry "that people may have not thoroughly considered what may go wrong", I feel those fears are founded (no offense) on ignorance. The system proposed here would replace only the primary layer in a multi-layered system. A replacement which not only closes more risk vectors than it opens, but shifts the risk factors which do exist further from likelihood.

Who needs anti satellite weapons? In the second Iraq war, wasn't Iraq using GPS jamming equipment for a while? Heck, last time I was in DC I noticed that my GPS would blink out around the White House. Although direct jamming equipment I don't worry about as much as the possibility of spoofing equipment.

Spoofing a moving GPS receiver is near impossible, and spoofing a receiver which is in the air harder still. It is common for quality GPS navigation antennas to reject all signals from below, as they are assuredly multipath. Unless your spoofer is above the aircraft, monitoring the aircraft's position, and delivering unto the aircraft a targeted spoof signal specifically designed to be plausible, it will be rejected and you will have created nothing more than an expensive jammer.

what if some big foreign country who has anti satellite weapons decides to blow up our GPS satellites?

A - Shooting down a bird would be an act of war. A stupid act of war as the shooter would be obvious. You can't secretly launch such an attack. Repercussions would be quick and severe.

B - While the possibility exists, the GPS birds are way up there (12,500 miles), there are currently 30 of them (a more than 2x redundancy for this type of navigation), and 10 more are going up soon.

Not to mention the fact every bird is in constant view of at lest one ground monitoring station (any disruption or degradation would be noticed immediately) and fallback procedures (increase traffic lane spacing) are in place.

Many perpetual leases

As are some easements, to clarify. Point is there are many ways the agreements can be written, and many do not involve a simple one-time payment.

Electricity in TX costs between 9 and 18 cents per kw hour

Those are residential rates. Commercial rates are lower, industrial lower still, and wholesale - the market wind farms (and other generators) sell into - lower still.

Once you've paid off the farmer for the land usage rights

Many perpetual leases are written so that the grantee pays so long as they hold rights.

Who, exactly, are you willing to kill / let die to achieve your goals.

*assuming anything but the absolute worst geometry.

The distance an aircraft is above the surface of the ellipsoid is inconsequential.

Close, but no cigar:

All receivers should be assuming you are on the surface of the earth. There are only two possible solutions with a three bird fix, and one is either way off the surface of the earth and/or moving at an improbable rate of speed. You need the fourth to get a lock, though, because you need to solve four things, not only the ambiguity of a three sphere intersection, but also the correct time.

Once you have your receiver clock synched, though, you can run with three birds as long as you are happy with the accuracy provided by your internal clock. This is one of the ways Assisted GPS over the cellular network provides such fast locks: Not only can the relevant part of the almanac be sent to your phone over a higher bandwidth connection, but you have a synced clock to start and thus only need three sats.

DGPS via cellular is another big bonus, but not relevant here. ;)

Uh, corn syrup is ~ a 50/50 mix of glucose / fructose. High Fructose Corn Syrup is just that, higher in fructose.
We're talking a 40/60 to 25/75 mix of glucose / fructose.
So your entire comparison to sucrose is wrong from page one.

Cars are not inherently inefficient.

And neither are SUV's.

bogus.
Just spec'd a Ford F250 diesel standard cab truck on Ford's website. 12MPG, 12,500 pound towing capacity (the max I could get).
Compare that to any OTR commercial "big rig" which has half the fuel economy, but over six times the towing capacity.
Face it, this SUV is as third as efficient as it could be, and it has a better capacity:consumption ratio than most out there.

So in an attempt to create a "quick fix" you are advocating the permission for people to bury their heads in the sand and let life pass them by because they got hurt and don't want to feel bad?

As I previously said, there is a group of people who, despite honest effort and therapy, do not recover from traumatic events. There is no support for a quick fix anywhere in my earlier comments. Stop attempting to straw-man this.

I think you ought to either drop the programming analogy or realize that there are no "bugs" in our "software." Humans can't "upgrade their firmware" to overcome "short-sighted design" or development. They either adapt at a conscious level or a subconscious level; the former has a much more obvious affect on their abilities, while the latter is harder to actualize, but can be just as potent

Bullshit. There are clearly innate and instinctual functions of our brain our higher processes wish they could override. We have an onion of a brain with layer upon layer of functionality, but also layer upon layer of cruft.
Flinching when you know the person isn't going to hit you. Accelerated heartbeat when you know it is only a movie. Goosebumps when you know you have no hair to fluff. Even the annoying sensation of cold when you know you are able to maintain core temperature. All of these are examples of where, despite conscious will, our base programming still rules.

It sounds to me that you are letting people suffer through ignorance and allow them to experience the same things later, which they will then also need to be treated for.

You're assuming these people can learn. I'm arguing there is a class of case where normal brain function has been so disrupted by an overactive response to an emotional event that learning from the event is impossible. Despite your insistent wish to believe that isn't so.

Do I think that emotionally damaged people deserve a second chance? Sure, but with the proper tools and in the proper environment, not through the use of a one-size-fits-all memory supplement (or otherwise)...

Who says this is a one-size-fits-all solution? Not I. It appears to me that there is either a reading comprehension problem or a desire to straw-man again.

...that doesn't solve the victimization problem of the event from reoccurring.

A non-functional personality can solve no problems. Either we do what we can to restore advanced functionality (and maybe this will prove an effective tool to do so) or we accept the person as a loss. Many really are just that far gone.

No one just "get[s] over it." Every individual, based on their prior experiences will take a given situation and either adapt to it to the best of their abilities, perhaps by adding it to their experience or by "moving on" and ignoring it even though the effect is still with them at a subconscious level.

Tomato, Tomato. Potato, Potato.

You can't tamper with the learning process of gained experience because nature doesn't breed it out of the gene pool anymore. Modern medicine has, in my opinion, overcome the acceptable boundaries of emotional science without considering the long-term health effects of just throwing pills at people.

Learning to adapt and overcome is far too important to let us forget. No matter the cost.

Either you're assuming there are not legitimate "bugs" in our software which prevents some from properly processing emotional trauma (And there is no evidence this "some" are even genetically inferior, or even different. The jury is still out over if this is a result of predisposition or the circumstances of the specific trauma.) OR you're proposing we "improve the race" by letting the weak fail. (So we let people suffer today in order to carry out your vision of evolution?)
No thanks either way
.

You speak as if our brain's software is without bugs. If you had seen the suffering and disablement that intense, often unreasonable, emotional pain can inflict on some people even years after the traumatic event, perhaps you would be less dismissive of an attempt to patch this particular bug.
Expose X people to a horrific event and a high percentage of them will show the ability to get over it. There is that outlying group, however, who (despite honest effort and therapy) seem to have an overactive emotional memory system which prevents them from ever coming to terms with what happened.
