Hyperspectral Optical Technology is a sensor system which detects hundreds of "spectra" or measurements of reflected or emitted energy. Scanning many channels across a narrow bandwidth, the sensor system is able to provide detailed information on about target's spatial and spectral patterns. The system works by breaking the optical spectrum into as many as 30 unique colours at a rate of 30 times per second. The sensor quantifies the spectra energy in each image and than builds a filter which is "tuned" to the specific target. For specifically marijuana further processing is needed, but from an elevation of 5,000 feet or in horizontal position several hundred yards this sensor is able to detect marijuana. Even through heavy vegetation, it is able to differentiate between recreational cannabis and industrial cannabis, due to specific objects and substances having unique "spectral signatures". Natural, man-made objects, different vegetation and even various types of building material can be detected. In a high elevation it is able detect chemical or biological weapons, run bomb damage assessment of underground structures, and foliage penetration to detect troops and vehicles movement.
UAVs In a Mississippi town called "A precious coin in the purse of the South.", named after a spanish coin by the french inhabitants of New Orleans, Picayuna has one of the newest method of law enforcement. A Unmanned Aerial Vehicles or UAV is semi-autonomous robot which flys around and with the use of sensors spies on civilians. Air-O-Space teamed up with the Picayune Police Department to conducting information gathering and surveillance, or in other words used the UAVs to search for, locate, and videotape marijuana fields, in the name of the "War against Drugs". The use of UAVs is likely to become more apparent, especially in nations which police spy on their citizens
Is it not an invasion of privacy for that UAV to do that? or.......
