The redoubtable Ptolemy even plotted latitude and longitude lines on his atlas’s 27 maps‚ though the farther one got from the known world centered on the Mediterranean‚ the dangerously less reliable they became. Even before Ptolemy‚ there were sailing directions -- the Greeks called them periplus or "circumnavigation"

could be situated in a local area and tracked down in “real time” or located anywhere on Earth and identified virtually. As you know‚ every point on Earth can be identified by latitude and longitude. In this lesson‚ you studied how to read points on a map in degrees‚ minutes‚ and seconds of latitude and longitude. For example‚ the Space Needle in Seattle‚ Washington‚ is located at approximately 47° 37’ 14’’ N‚ 122° 20’ 57’’ W. Use your map reading‚ Internet searching‚ and reasoning skills to find

measurements (sights) between celestial bodies and the visible horizon to locate one ’s position on the globe‚ on land as well as at sea. At a given time‚ any celestial body is located directly over one point on the Earth ’s surface. The latitude and longitude of that point is known as the celestial body’s geographic position (GP)‚ the location of which can be determined from tables in the Nautical or Air Almanac for that year. The measured angle between the celestial body and the visible horizon is directly

the status of the Vehicle on demand. For doing so an AT89S52 microcontroller is interfaced serially to a GSM Modem and GPS Receiver. A GSM modem is used to send the position (Latitude and Longitude) of the vehicle from a remote place. The GPS modem will continuously give the data i.e. the latitude and longitude indicating the position of the vehicle. The GPS modem gives many parameters as the output‚ but only the NMEA data coming out is read and displayed on to the LCD. The same data is sent to the

lines of constant latitude and constant longitude‚ is constructed by reference to the rotation axis of the Earth. The primary reference points are the poles where the axis of rotation of the Earth intersects the reference surface. Planes which contain the rotation axis intersect the surface in the meridians and the angle between any one meridian plane and that through Greenwich (the Prime Meridian) defines the longitude: meridians are lines of constant longitude. The plane through the centre of the

Latitude and Longitude Before we learn about the characteristics of our environment‚ let us first talk about the location of the Philippines. Where is the Philippines? The Philippines is on Earth‚ of course‚ but where exactly is it located? To answer this question‚ you have to learn a new skill: locating places using latitude and longitude.
