Reducing the Risk. A lack of answers is part of what makes sudden infant death syndrome (SIDS) so frightening. SIDS is the leading cause of death among infants 1 month to 1 year old, and claims the lives of about 2,500 each year in the United States. It remains unpredictable despite years of research. Even so, the risk of SIDS can be greatly reduced.
Using the Latitude Longitude Coordinate System. The latitude longitude coordinate system uses angular measurements to describe a position on the surface of the earth. The system has been in use, with little change, since the astronomer Ptolemy used them in his first world atlas in A.D. 150. Mariners and aviators have been the primary users of latitude/longitude in the past. The system is used on a world wide basis and many different types of maps have lat/lon markings.
Senior Fellow in Electrical Engineering. The longitude of a point on earth is the angle, east or west, between that point. and a certain reference line on the earth. If you take a globe or a map and draw a line through all the points that have. exactly the same longitude, the line you get is the meridian of that longitude.The reference line is the meridian of zero longitude, called the Prime Meridian.atitude is the angle north or south between a place and the equator. Longitude is the angle east or west between the same place and the Prime Meridian. With only those two numbers, you can nail down any point on the Earth. 1 person found this useful.
