yeah they can detect pot plants over 2 inch's high and in GA they been finding a lot of plants but i think that anyone that grows in or on there property is stupid there are woods and stuff everywhere......

No, they cant spot plants over two inches high. A pot plant is VERY hard to notice at only two inches, even 2ft, not to mention it's practically a seedling. Secondly the heat sensor "myth" is total bullshit. The concept that a plant will emit infrarred radiation at a different frequency than other plants, which btw are also budding, is total bs. Lastly, copters dont come out till flowering season, late august onwards, as that's their best chance of catching growers and a plant visible from the air.

THE BLACK HELICOPTERS ARE REAL!
By Bill Weinberg For all of their xenophobic paranoia about United Nations conspiracies to take over America, the militia movement is playing on some fears which are, alas, very real. All those sightings of mysterious unmarked black helicopters, for instance, are not hallucinations. The black helicopters are real. But the enemy isn't the UN, it's Uncle Sam. That's what Montana tax-resister Calvin Greenup should have realized when an Idaho National Guard chopper swooped down over his ranch last March. He got on the horn to his militia buddies, and within a half-hour some 20 rifle-toting rednecks had arrived to protect his land in the military onslaught that was expected to ensue. But the AH-64 Apache didn't return that day. Officials later said the chopper was on a routine training flight, and overpassed the Greenup ranch by accident. |

Remote Sensing Cannabis sativa from the Sky: Research, Possibilities and Challenges
Due to the stealthy nature of law enforcement there is not much current information concerning hi-tech remote sensing of Cannabis plants available to the general public. If law enforcement officials shared the latest developments, then individuals growing the Cannabis would make every effort attempt to hide their plants. Limited information has been made available by the United States Department of Agriculture. The following points were submitted to the Office of National Drug Control Policy from the research arm of the Department of Agriculture. (Walthall, 2003). Cannabis plants possess leaf and canopy spectral reflectance patterns similar to other green plants. The contrast between Cannabis and other plant canopies is highlighted in the green, red edge and near-infrared wavelengths. There are more spectral differences between Cannabis and tree species than with annual plants. Microscopic structures on Cannabis leaves cause specular reflectance which causes the leaves "emerald-green" color. Research should take into account the efforts that growers go to in masking their crops from the sky. USDOJ Cannabis and a Variety of Trees This graph shows how Cannabis' reflectance is quite distinct from a variety of trees from a deciduous forest. A comparison of trees from a California forest was not available on the World Wide Web. However, it is reasonable to assume that differences do exist between the perrenial plants of California and Cannabis. These differences could be exploited to help law enforcement spot Cannabis plantations from the sky. The most current development in Cannabis cultivation would render canopy analysis ineffective. During the 2005 growing season Cannabis plants were found growing underneath Chapparal vegetation. Workers had gone onto a shrubby hillside and hollowed out the understory. The upper canopy of native plants had been left intact. The Cannabis plants were growing under the natural canopy. Growing under the canopy stunted the Cannabis plants but this technique definitely masks the plants from the sky. USGS Spectral Signatures of Vegetation and Soil Spectral signatures of vegetation and soil could be used to identify illegal plantations. A Cannabis plantation growing in a Chaparral biome could be detected based on the quantity of water in the leaves. As the Chaparral vegetation dries out in the summer and fall, the irrigated Cannabis plants would be green and full of water. Looking at green versus dry vegation reflectance data would certainly identify situations that were are not illegal activites. Springs, creeks and small ponds would all have green vegetation while dry vegetation would occur nearby. Water content analysis would require considerable ground truthing to develop an effective identification system. USGS Spectral Signature of PVC Pipe Remote sensing could be used to identify manmade materials that are used for the cultivation of Cannabis plants. One unique item not expected to be found on National Forest lands is PVC pipe. PVC pipe is used in irrigation systems to keep the plants growing. PVC pipe running all over a hillside in a National Forest would certainly warrant a closer look. One shortcoming of this technique is that the growers could bury or cover the irrigation pipes. Masking the PVC pipe would be considerable amount of work but the financial returns from Cannabis crops is substanial. According to current available information there is no sky-based remote sensing of Cannabis sativa on public lands in California. Law enforcement agencies are using effective ground-based systems to locate Cannabis plants on public lands. Perhaps, in the future, more time and effort will lead to the development of sky-based remote sensing systems that will get the job done. |

Well that's a good thing to know. I'm sort of shocked they would go to this length, but at the same time, i dont see this as being a realistic option. Index values, (ie % of reflectance) are notoriously unreliable. i think that the graph is fairly congested, even before they start to introduce stuff which consists of an almost equally green matter.
Nonetheless, i stand corrected, it is not a "myth", but i still smell bullshit. I cant see this being a realistic and effective method. I mean, we're talking about sensing the difference between an "index" value of reflectivity of about 8% from a couple hundred feet in the air, assuming they have a direct shot at the plants. I could see all this being very effective in a vacuum, but not on a massive uncontained scale. I know from my experience that a margin of error, in scientific experiments, occur usually to a proud degree of at least 5%. The goddamn thing would be beeping every 2 seconds lol.

mogie you had me up until george washington. because that man loved the herb, and it was until after him that it became criminilized.
