And the company, which is among the most innovative in the world, just released its newest drone, the Phantom 4, last week. DJI successfully raised more than $575 million in VC funding last year, more than enough for operations, so an IPO in the near future is unlikely.

The demarcation of the longitude coordinate is done with lines going up and down are called the meridians. A figure to the right shows a few meridians. Longitude ranges from 0Â° to 180Â° East and 0Â° to 180Â° West. The longitude angle is measured from the center of the earth as shown in the earth graphic to the right. The zero point of longitude is defined as a point in Greenwich, England called the Prime Meridian.
Lines of Longitude define how far east or west a location is from the Prime Meridian, the focus of this lesson. The Prime Meridian is an imaginary line that, similar to the equator, divides the earth into eastern and western hemispheres. It is sometimes referred to as the Greenwich Meridian. All lines of latitude and longitude are measured in degrees.
