I want GPS on my TV remote control, so I can find it.
Those terrible park officials! They're having those poor rats put to death when all of Ghod's creatures are sacred! What they should do is organize a nice conference where the rats and the seabirds can sit down and air their grievances peacefully, in a spirit of mutual harmony and understanding.
Seriously, this is pretty cool. Any time technology increases mankind's killing power, I've got to cheer a little bit. After the rats, how about some pigeons (also known as the "gutter bird" and the "winged rat," according to Kent Brockman)?

The helicopter just used the GPS to navigate. Meanwhile some guy used GPS to navigate himself out of the desert, and a fisherman captain found his way to pango pango.

their statenments about delivering sprays and pellets by air with an accuracy of 'within a foot' would be quite a thing to see, especially when you watch what a helicopters downwash does to items dropped from below it, and allowing for the pilots abilities (remember, the computer is not flying the aircraft here) - I think there cuold be a bit of wishfull thinking involved here, but I'm sure it looks good on the enviromental reports.
I assume they are using DGPS, which is generally available, for example look at:
http://www.navman.co.nz/oem/products/gps/rec
also for a basic discussion:
http://boats.com/content/default_det
but this will certainly not guarantee you the accuracies they are claiming, at least not unless they are dropping the loads on the fixed beacons DGPS relies on (most provided by the coast guard in the US, also at some airfields).
DGPS is a wonderful development on GPS, but is still not that good. Interesting the russian GLONAS system is a little better (if more expensive for receivers) than GPS.
Starwars missle defense system.. aww yeah. :)
If they miss just a male and a female rat, the new rats will breed and the offspring will be immune to GPS :=)

...that they sprayed enough pesticide on a small island to kill all 100-300 rats. Either they killed them all, as well as every other living organism on the island that is roughly the same size as a rat, or they didn't kill every rat. Rats are decently sized, it's a lot different than killing insect pests. Insect pests might require a few ppm (parts-per-million) pesticide in the air, but the kill a rat, hamster, gerbil, mouse, bird, anything of that size, would require much much more "pesticide." They must have required quite a lethal dose to get all 100-300 of them, as the article says. Not to mention the fact that the dose would have to be increased to take into account that a lot of the particles will attach themselves to plants, trees, etc... which are above ground. This will not contribute to airborn particles, and will not be able to kill a rat (unless they are of the mutated tree-climbing variety!) So the bottom line is, the dosage must have been huge for this small island. Or else there are still some rats around which have survived. They have probably started mating already. I think bringing in some owls might have been a smarter idea.
A Trimflight 3 system. I work next to the people who designed this system here in New Zealand. And they might have even been using the GPS receiver that I write firmware for, the Ag214 (Also known as the MS750). But they were probably using the Ag132 which only does DGPS instead of RTK.
I'm sure this URL will be circulating around the Ag division of Trimble tomorrow :-)

Perhaps these farmers would be interested in an offshoot of our quite popular line of nut transportation satchels.
They're mainly used to transport grain, and are specifically designed in order that when shipping grain, the designated recipient is assured that the entire shipment will arrive intact.
We call it the CornWhole system, and once put in place, it's extremely difficult for the target to be penetrated by any agent (animal or chemical) except those specifically authorized.
We hope that it will expand in practical use, as it provides for particularly efficient transport, especially when coupled with the RNTP protocol we've established.

... so they didn't have to soak the place with RAID. I'm guessing that it is possible to make bait which is attractive to rats, but not birds.
Santa Anacapa is three really small islands, so I doubt there are any native land mammals there (or ones which aren't common on nearby islands.) Santa Cruz island has some native foxes, but that's about it. The seals are quite happy in the area, though. Maybe the beaches are the areas where the poison isn't allowed.
They could have just wrecked a second ship that happened to contain several hundred cats.

Globally Positioned Technology More Precise, Accurate Way To Help Agriculture
Jim McLain March 20, 2002
From microchips implanted in the necks of cows to gain quick computer access to their breeding and medical records to satellite-guided tractors that keep growers from skipping or overlapping field sections while spraying pesticides or fertilizers, sophisticated electronics are found throughout agriculture.
When Channel Islands National Park officials needed an estimated 100 to 300 non-native black rats exterminated on the east side of environmentally sensitive Anacapa Island last fall, Oxnard-based Aspen Ag Helicopters got the call.
The kill was necessary because the rodents, descendants of rats that reached the island by way of a shipwreck a century or more ago, were decimating the populations of two rare seabirds. It was difficult work, though, because the poison was banned from parts of the island and allowed in other areas in concentrations of no more than two pellets per square foot. And, of course, none of it could reach the ocean.
Sophisticated airborne equipment normally used to precisely guide the spraying of fertilizers and pesticides over Ventura County's citrus and avocado orchards and strawberry and vegetable fields got Aspen the job.
Pilot Kevin Miskel, who flew the mission, said it worked perfectly, though killing rats was hardly what the equipment's inventors envisioned.
"It was pretty critical. The criteria were pretty tough and the GPS really helped," he said. "It did everything we hoped it could do."
Satellite, Radio Links
The GPS Miskel mentioned is a global positioning system, satellite tracking equipment that is a lot more expensive and technical than the navigation devices some luxury car owners use to locate a cozy bed and breakfast or a grand French restaurant. Installed on one of Aspen's beige and brown Bell Jet Ranger helicopters in 1999, the $16,000 digital system links itself to two satellites and three U.S. Coast Guard radio navigation installations.
Just by flying a field's boundaries, a pilot can use the system to precisely map it, set up tracks for spraying that are accurate to within one meter, or 39 inches, and have a permanent record of what was sprayed and what wasn't. Other equipment controls the spray so no part of the crop gets too much or too little even in windy weather.
Called TrimFlight 3, the system is the more sophisticated of two owned by Aspen and only one of dozens of high-tech machines and devices that inexorably are taking the guesswork out of farming in Ventura County and elsewhere. Technology is not new to agriculture, but some of its recent innovations rapidly are improving growers' odds of succeeding in one of the world's oldest endeavors.
Widespread Use
"Technology is being used everywhere in Ventura County farming, everywhere you look," said Rex Laird, the Ventura County Farm Bureau's executive director. Added Kenneth Solomon, head of the Bioresource and Agricultural Engineering Department at California State Polytechnic University, San Luis Obispo, "I'd be hard-pressed to find any particular area of agriculture that wasn't employing these techniques."
From microchips implanted in the necks of cows to gain quick computer access to their breeding and medical records to satellite-guided tractors that keep growers from skipping or overlapping field sections while spraying pesticides or fertilizers, sophisticated electronics are found throughout agriculture. Computers are being used on more than 55 percent of American farms today, up from 38 percent in 1997, the newspaper Investors Business Daily reported last month.
Some tractors have devices that monitor yields while a crop is being harvested, enabling a grower instantly to spot which parts of his land are underproducing. Infrared satellite imagery vividly showing coloration changes on large tracts of farmland also is being used to track the spread of pests and diagnose some plant and soil problems.
"The different shades of red show almost instantly where your weak spots in the field are," said Darrell Nelson, president of FGL Environmental in Santa Paula, a company that uses computer-generated chemical analysis of soil and plant tissue samples to pinpoint problems for California growers. "The satellite technology is just really awesome right now. We download photos of our orchards that are really quite good quality."
Stay with the Pace
Founded in 1925, privately-held FGL Environmental once used what Nelson called old-fashioned wet chemistry to find the lack of nutrients or high concentrations of toxic soil minerals that cause crop trouble.
Today, the company uses 70 employees and a lab building filled with computerized analytical equipment valued at more than $5 million to do up to 600 mostly automated diagnostic tests daily for growers from Southern California to Stockton. Its gross sales last year were $5.25 million, up $500,000 from 2000. This year, the company expects to spend $500,000 on new equipment.
"We either have to stay up with the pace of technology or get out of the way," said Nelson, who has been with the company for 31 of his 59 years," and we're not ready to get out of the way."
Still called Fruit Growers Laboratory by most growers, the company quit using its legal name and began calling itself FGL Environmental more than a decade ago when it expanded into soil engineering and water quality testing for the construction, water and environmental-impact-report-writing industries.
Today, those sectors account for 75 percent of FGL's business, Nelson said, but its agricultural work remains vital. Its chemists and machines heat soil and plant tissue samples enveloped in inert gases to more than 10,000 degrees and measure the light from burning tissues to break down components into the parts-per-billion range. They're seeking nitrates, phosphates, chlorides and other elements.
"We measure some items for electrical conductivity. The higher the conductivity, the higher the salt content," Nelson said. "This is where the interpretation comes in. If you know how to interpret electrical conductivity, we can tell you whether the soil is too salty for strawberries, but OK for broccoli or something like that."
Sophisticated Rat Killer
Aspen Ag Helicopters' high-tech GPS system was effective in eradicating those black rats from the east side of Anacapa Island last fall, but it required some low-tech help. The system is designed to disperse materials in a 360-degree swath, but because pilot Miskel had to keep the pesticide pellets out of the sea, the spray angle had to be cut to 45 degrees.
"We had to put an aluminum shield around the broadcaster (the chopper's on-board pellet container)," Miskel recalled. "Our high-tech system told us where to throw the stuff, and this low-tech device kept it from going the other way."
Steve Ortega, the National Park Service biologist in charge of the project, said it was so successful that Aspen almost certainly will get the job this fall when rats on the middle and western side of Anacapa Island are targeted. Black rat kills are also planned for the park's other islands.
"The area where they worked is rat free right now," Ortega said. "Their digital GPS unit gave us real time tracking of exactly where the poison was dropped."
Computer-Generated Maps
Rob Scherzinger, manager of Aspen's ag program, was not surprised the park people were satisfied. The company uses its equipment on about 250 days a year, mostly for agricultural applications, but also to spread fast-growing grass seed in areas blackened by brush fires and pour copper sulfate, which kills algae, into Southern California reservoirs.
"They tell us where they want the stuff, give us the latitude and longitude to go from point A to point B, and all we've got to do is plug in the GPS and we get it right where they want it," Scherzinger said. "The algae doesn't like it, but the fish don't mind it."
In farming operations, the GPS-guided choppers can cover 60 acres in an hour, using a computer-generated moving map that keeps pilots following its green lines to within one foot of a perfect course, he said. Growers pay about $1,000 an hour for the service.
"It's one of those things where if you don't have it you just miss it something awful," Scherzinger said. "We use it every day we spray."
Actually, this will solve all sorts of problems... being closer to its natural source, we'll be better able to fight terrorism. And we can feed the bodies of the dead Jews and Arabs to all of those cannibal heathens whom we're always giving "foreign aid" (read: you no workee, but you get free foodee) to. And Bloody Beach will make it much easier for us to launch the Asian** War (again China and North Korea).
Man, am I sick of hearing the news about Israel and Palestine every day. What? You say that there was a suicide bomb attack? You don't say!! I would never have guessed, especially because there are suicide bombings every day!! Eh? How do I know that? Because you tell me, every day!! You might as well report on the sun coming up and call it "news." Blah blah blah, bloody conflict, blah blah blah, peace talks breaking down. Americans don't care, and we shouldn't, because the only effect it will possibily have on us is making gas prices go up. We're a little busy right now -- see, a whole other group of Middle Eastern fuckwits are trying to blow things up in our homeland. And things are made worse by a bunch of liberal scum who refuse to accept that they have a homeland, and that it's the US, and they're going to have to forget their usual sad "equal rights" (i.e. more rights for minorities, fewer rights for the majority) and "protect the environment" (i.e. make it impossible to sustain our American lifestyle) and "campaing finance reform" (i.e. make it impossible for conservatives to buy air time, so that the liberal-bias media will be be free to promote liberal agenda, apparently uncriticised) BULLSHIT and watch the backs of their countrymen.

** Why do yellow people think it's cool to call themselves "Azn?" I must be missing something -- how does misspelling your ethnicity show "ethnic pride?" You live in a Western country and you wear Western clothes and you speak a Western language; you're about as "Azn" as President Bush. If you're so proud of your ethnicity, learn your ancestors' language and write your ethnicity using your people's own language, don't just take an English adjective-- a pretty recent one, I might add; ten years ago you were "orientals;" twenty, "gooks" (hey, I'm no fan of racial slurs, but we were fighting an "Azn" country and I'm not going to rewrite history to hide bigotry. I'm of German blood and have no false ideas about the mistreatment my Americanized family received during WWII). I play a lot of FPS games online, and always laugh at the idiots playing with "Azn" in their names. Yes, we -- meaning all intelligent people -- are laughing at your sad attempt to be cool. Hey, I'm white, maybe I should start telling everyone that I'm "whyt." Oh, wait, I forgot.. militant racism is fine for minorities ("Azns," ghetto kids, Zionists) but it's "bigotry" for a European person to have anything but hatred for his ancestors. You know what? I'm not naturally bigoted, but I'm going to become a racist if my people don't stop being oppressed. Revisionist history and affirmative action are going to to a lot more harm -- in the form of violent backlash -- to minorities in the long run than they will help minorities in the short run.

Hey, speaking of BULLSHIT, what do you think of the latest lawsuit against Phillip Morris? It cracks me up that these losers get any money at all -- hey, you brain-damaged bitch, low-tar cigarettes may be better than unfiltered ones, but they're still bad! Jesus Fucking Christ on a motherfucking pogo stick, anyone who continued smoking after the mandatory warning labels were added to the packages has no fucking excuse in hell for complaining. Hey, assholes! Alcohol kills brain cells and destroys your liver! Why not sue alcohol companies? I don't see warning labels on their products, which are just as harmful as cigarettes! GET A CLUE, FUCKTARDS -- tobacco may have fucked up your lungs, but you were born stupid, so you have no right to complain to the company that supplied the poison that you purchased and inhaled, knowing all the while that it was a health risk.
We live in such a stupid world with so many stupid people that it makes you want to kill yourself.
Or kill other people.
And that, my friends, is why John Walker Lindh is innocent.

I don't know about all this. Increasing yields, paying huge sums of money... in the end, it still means that less and less human intervention is needed, less jobs are created, big farms get richer and smaller farms just can't keep up.
It's not really like technology is helping democratise here, is it?

Rats living in the wild 'elect' a food taster, who tastes any new food, while the rest of the pack watches. If he/she becmes ill, the rest of the rats don't touch the food.
Even when living in captivity alone, rats will taste a tiny bit of new food, and see if they become ill, finishing the food if not, so the posion they used would have to be increadibly strong to kill a single rat with a single bite, or very slow acting to kill a pack after the taster has sampled it and given it the OK.
Clever little critters. I've kept domesticated ones for many years, and they never cease to amaze me with things they do or learn. You can house train them, get them to come when called, and do simple tricks for treats, just like dogs.
It is reckoned that living in a big city, you are never more than 3 yards away from a wild rat. Nuff said!

I can't even afford a call phone, why should rodents be allowed to live with GPS!?
I agree with this post: Kill all the rats with GPS, and give us needy humans some of that technology!
Who moderates the meta-moderators?
You forgot the application of the Heisenberg Uncertainty Principle: The more you know about the position of the rat, the less you know about its velocity. Thus you simply keep measuring its location very precisely until its velocity happens to transport it away from the island. When it vanishes from sight you no longer know its location, so it stops moving and falls in the ocean.
Damn, and I followed the link to see how they tuned the GPS sattelites to be used for pest-control. They must have had more than one military use, global doomsday machine?
This sounds vaguely similar to Sewer Shark, an old school game for Sega CD. Basically, you flew around in this hovercraft shooting at rats. Now this was entertainment! I can only imagine that the helicopter version is ten times better...
mstyne: real name, no gimmicks
This reminds me of the situation on the Galapagos islands.
Goats had been introduced back when the first sailors had arrived. Now they are upsetting the balance of the ecosystem and must be erradicated. Unfortunatly, due to the delicate nature of the ecosystem, and the general lack of navigability around the island, goat removal options are few.
One is to use $20,000 dollar goat attack dogs (I swear on my karma I'm not making this up) with self-destruct collars (if they attack anything besides goats)
The other is called the judas goat program. One goat is captured, his horns painted and a tracking device attached, then let lose. In a few days he will find another goat herd, at which time a helicopter with hunters (goat snipers, again I'm not making this up) flys over the herd, and methodicaly pick off each goat except the judas goat.
1) We have a fragile ecosystem that is being decimated by interloping humans^H^H^H^H^H^H^Hrats.
2) This is a protected environment for rare seabirds.
3) The very first ecological disaster that led to the banning of a pesticide was due to it's negative effect on the indiginous bird population (DDT).
Conclusion: we should drop a ton of poison pellets in this National Park in order to save the birds.

Not the type of story I like to see on /. Domesticated rats are intelligent animals that make *great* pets. I understand that these particular animals needed to be killed, but it's a shame, and that shame is not the focus of this story; rather it is the gps. Technology is not more important than life--any life.

I actualy live in Oxnard, and my father is a farmer. My family has known the folks at Aspen as long as I can remeber.
I am also pretty familiar with GPS's and Helicopters.
one more thing I am familiar with; Anacapa Island, and I just can't see how GPS would help with this job. Anacapa is little more than a rock that juts out of the ocean about 14 miles off the coast of California, you can see it from anywhere in ventura county that has a clear view of the ocean.The island is broken up into 3 smaller islands each not much larger than a couple of hundred yards. Any sufficently detailed map should be all you would need to precisley dump your poison.
It was a joke. Chill.
You left off the rest of the story.... they paid the Iscariot goat 30 bucks for his troubles, and he tried to turn it down. But they said take it, and he did. Then guilt came to him, and his goat heart was heavy, and he went off and hanged himself. (and became goat jerky)
It may be cold, but at least it's clear.

The Park service could have made some money off this whole thing. Just call Mark Burnett and let him hold the next edition of survivor on the island. Then just them eat the rats, and plus you can charge the contestants a campground fee.
My Weblog
Then it says that the exterminators killed 100 to 300 rats.
Maybe I'm missing something, but wouldn't a rat population given 100 years to grow without interference from humans number a lot more than 100 to 300 individuals by now? Or are they saying that the rat population was already held in check at 100 to 300 by the carrying capacity of the ecosystem?
