This technology is in widespread use today, and the growth will most likely be based on the number of rich countries engaged in âwarsâ at any given time. Instead, Consumer and Commercial Drones are where the real growth is expected to be at. You may have decided you wanted to invest in drones because one was buzzing around your neighborhood recently, or you noticed theyâve started cropping up an awful lot in reality TV, NatGeo shows, and YouTube videos.
Degrees and Minutes The distance between degrees of longitude is about 60 nautical miles at the equator. It is less further north or south as the longitude lines converge towards the poles. Degrees of latitude are always 60 nautical miles apart.At the equator, a grid of 1Â° of longitude by 1Â° of latitude covers about 3,600 square miles.For greater precision, degrees are divided into 60 minutes (') - of distance, not time.y comparison, a statute mile is 5,280 feet or about 87% of a nautical mile and a kilometre is 54%. One minute of latitude equals one nautical mile and degrees of latitude are 60 nm apart. The distance between degrees of longitude isn't constant because they converge towards the poles.
The Earth is still divided equally into 360Â° of longitude with 180Â° being east of the Prime Meridian and 180Â° west. Longitudinal coordinates are divided into degrees, minutes and seconds with 60 minutes making up a degree and 60 seconds comprising a minute. For example, Beijing, China's longitude is 116Â°23'30E. The 116Â° indicates that it lies near the 116th meridian while the minutes and seconds indicate just how close it is to that line. The E indicates that it is that distance east of the Prime Meridian.
