GPS, GIS and VR for Precision Farming
In the article “GPS, GIS, VR, and remote sensing technologies continuing to evolve” the author named Robinson Elton, mainly focuses on the advantages of GPS, GIS and few more developing technologies used for precision farming in U.S.
This article points out that, the NAVSTAR Global Positioning System, a network of satellites was launched as a 24th satellite, by U.S Air Force in 1993. Earlier, GPS was a key tool in U.S military and now-a-days it is playing a crucial role for precision farming in U.S. With the help of this technology anyone with a GPS receiver will be able to determine his location on Earth in three dimensions namely longitude, latitude, and altitude at an accuracy within one inch.
This article also states that precision farming uses four other technologies to gain a widespread use in agriculture. They are, Geographical Information Systems, variable-rate technology, the yield monitor, and remote sensing. Importance of all these technologies is discussed in this article. “The geographical information system (GIS) is a way to make maps that show variability of field or crop characteristics. The remote sensing technology uses satellite imagery to capture the spectral reflectance of a crop and correlate it to the nitrogen levels, plant health and soil type” (Robinson, 2007).
This article further states that the cotton yield monitor was introduced commercially in 1998. The yield monitors are linked with GPS to create yield maps for crops. A yield map was considered as a great educational tool in an academic point of view. Information gathered from farmer experience, research and yield monitoring can be used to take proper decisions regarding the crops to be harvested. “”MY IDEAL WORLD would be for every piece of equipment to have GPS, tracking of as-applied data, and relay all that information wirelessly to my central computer. The technology is there to do this — we just need to get it all put together.” says Ed Barnes, associate director of research. Cotton Incorporated” (Robinson, 2007).
This article concludes by stating the big challenge of precision farming is to manage all the information it creates. This article also discusses about some equipment-mounted sensors known as Green seeker and Crop Circle, which are used to detect nitrogen levels in soil. GPS is user friendly and also it can sense direction and speed. This is another key aspect making it more useful for the farmers. As navigation technologies do not require management skills, GPS navigation plays a crucial role in precision farming.

Hello,
it’s about precsion farming.

best regards
Great! Normally I in no way examine whole content articles but the way you wrote this information is basically amazing and this kept my interest in reading and I enjoyed it. You might have recieved superior writing abilities.
GPS is very useful specially the ones that are put on the Car dashboard. it can really help you drive on unfamiliar places.’~*
