Agriculture Crop Management and Production Improved by Satellite Remote Sensing Technology and Geographic Information Systems (gis)
Scientists for many years have been using satellite remote sensing technology, utilizing low and medium resolution sensors to improve water balance and farming yield assessment on large geographical scales around the world. With the availability of high resolution satellite sensors such as IKONOS, QuickBird and soon GeoEye-1, the current remote sensing NDVI algorithms utilized have become more accurate and reliable, providing detailed crop information for agriculture management to improve production and crop health.FAO (Food and Agriculture Organization of the United Nations) data indicate that annually 2500 km3 of freshwater is used for agricultural production, which amounts to 70% of the water resources that the world population consumes in a year. China is now consuming more than twice as much as what its ecosystems can supply sustainably, having doubled its needs since the 1960s, as indicated in a new WWF report. With the global population continuing to grow at a high Read more…
Scientific Explanations for Remote Viewing
Eighteenth and nineteenth century physical science had completed and embellished the “golden age of a mechanistic and deterministic models of the universe” where the universe and its constituents are ruled by rigid interactive forces that can be measured, phenomena that can be predicted using mathematical tools, and where the universe or any system operating within it is made of the sum of its parts.Light was thought to be an electromagnetic wave vibrating in an undetected, and later experimentally disproved media: “the ether”, at certain rates of vibration that would define its color. It was part of the electromagnetic wave spectrum that allowed one to perceive an electromagnetic wave as heat, light , radio waves, or other electromagnetic radiations depending on the frequency of its vibrations. This spectrum had been well-defined by the equations of the English physicist James Clerk Maxwell in 1864.Man’s biology was reduced to a mechanical system albeit Read more…
Car Alarm System to Sense a Motion in Your Dream Car
Car alarm is the kind of device which is needed to sense a motion and an electric current. The purpose of alarm is to detect someone tampering with your car and there by warning the intruder in a stern voice that there is an alarm set and he will be in trouble. The siren completely sounds for 30 seconds when the car senses a repeated and a heavy shock the voice shouts at a warning at a 127 db.The car alarm consists of an instant panic feature of women voice which would scream out for help and a car finder mode. This characteristic will help you to locate your car easily in a parking lot which is crowded totally. You can also set the sensitivity of the alarm by striking your car alarm to set the shock into a threshold. Once the car alarm is been completely set any impact Read more…
Pacific Borescopes Advanced Technology for Remote Visual Inspection
Borescopes,Fiberscopes,Videoscopes by Pacific Borescopesborescopes. why pacific borescopes can offer you the best selection of borescopes.lets face it- we are living in 2008 and nothing has changed much in this mature technology. as an example, go to your local camera store… look through the view finder on 4 or 5 of competing brands of slr cameras. can you see the difference in optical quality? probably not. they all look good! right? so whats the difference? well…. its the digital gadgets, storage, readouts, automatic functions etc. so what hasnt changed? the optics of course. optics are optics.borescopes dont have digital gadgets on them and are not sophisticated like a camera. everyone uses the same type of optics- the glass, the fibers, the lens, etc. borescopes are simple tools, nothing newer today than several years ago. why buy a high priced scope from one of the german or japanese manufacturers? or buy one Read more…
Nintendo Wii Remote Controller
You must be well aware about the popularity of Wii these days. Nintendo has created a game controller that combines the functionality of a remote control with the latest motion-sensing technology which is normally used in cruise control technique in vehicles. The result is Wii Remote some time known as “Wiimote” as well. The advanced technology used like optical sensor and accelerometer systems allows player to interact with the games being played on the screen. Well Wii Remote can be used as steering wheel, in tennis game can be used as tennis racket, for fishing game as fishing rod. Simply Wii remote controller gives you real world experience in gaming.Nintendo has now introduced new accessory for the Wii Remote, the Wii Motion Plus. This upgrade plugs into the Wii Remote and enhances its functionality by detecting other human movements, like twisting of the wrist. Sound amazing isn’t it? The ultra-sensitive Read more…
Starting a Remote Controlled Car Business
Starting a remote controlled car business is a serious commitment to a hobby that many people take seriously. However, it isn’t the business decision most people would care to take since it focuses on an enthusiast market. However, if your passion is for this hobby, and you know where to find other people with this same passion, then you have, at least, the first qualification of a good RC businessman.If you are considering opening a remote-controlled car shop, then consider the following while planning the course of your business.1. Passion.This is the most important question you must ask yourself before starting a remote controlled car business. Do you have the passion for remote controlled cars? While it is possible to still start this business even if you do not have much of a passion for this hobby, an innate love for RCs definitely helps.This is because as a remote controlled Read more…
Method of Making an Aerial photography
Another important role of these photos is to provide a foundation for collecting the spatial information needed. Data in the form of the satellite images or aerial photographs must be taken without any distortions, if you need to gather information useful for a mapping or GIS system in the case of roads, marine forms or vegetation.This process of correcting the distortions of a satellite image of aerial photograph is called orthorectification. This process allows you to make direct and precise measurements of areas, distances, angles, positions etc.Why an aerial photograph needs correction?The main challenge of an aerial photograph compared to a non-aerial photograph is that an aerial photograph needs perspective correction. An aerial photo is usually captured at an angle to the object being photographed. Here, the perspective of the photograph will be incorrect with near objects compared to distant objects. By perspective correction, the objects in the image and Read more…
