Distances Between Gps Marks

[wazza13974]

could someone please tell me the distances between marks say for example from 33 00 000 to 34 00 000 or

151 00 000 to 152 00 000

cheers warren

G'day Warren,

I don't know the distance between marks of latitude but from memory 1' is the equivalent of 1nm but I'm talking out of my rear because I don't really know.

What I can tell you is that there is no set distance between degrees of longtitude.... as you get closer to the equator 1 degree of longtitude actually gets longer in distance. Closer to the poles and it shrinks. Have a look at the lines of longtitude on a globe going from pole to pole. Because the earth is a sphere, the lines get further apart towards the middle.

Cheers, Slinky

Latitude

When looking at a map, latitude lines run horizontally. Latitude lines are also known as parallels since they are parallel and are an equal distant from each other. Each degree of latitude is approximately 69 miles (111 km) apart; there is a variation due to the fact that the earth is not a perfect sphere but an oblate ellipsoid (slightly egg-shaped). To remember latitude, imagine them as the horizontal rungs of a ladder ("ladder-tude"). Degrees latitude are numbered from 0° to 90° north and south. Zero degrees is the equator, the imaginary line which divides our planet into the northern and southern hemispheres. 90° north is the North Pole and 90° south is the South Pole.

Longitude

The vertical longitude lines are also known as meridians. They converge at the poles and are widest at the equator (about 69 miles or 111 km apart). Zero degrees longitude is located at Greenwich, England (0°). The degrees continue 180° east and 180° west where they meet and form the International Date Line in the Pacific Ocean. Greenwich, the site of the British Royal Greenwich Observatory, was established as the site of the Prime Meridian by an international conference in 1884.

How Latitude and Longitude Work Together

To precisely locate points on the earth's surface, degrees longitude and latitude have been divided into minutes (') and seconds ("). There are 60 minutes in each degree. Each minute is divided into 60 seconds. Seconds can be further divided into tenths, hundredths, or even thousandths. For example, the U.S. Capitol is located at 38°53'23"N , 77°00'27"W (38 degrees, 53 minutes, and 23 seconds north of the equator and 77 degrees, no minutes and 27 seconds west of the meridian passing through Greenwich, England).

Hey Carl... I know who I'm going to call the next time I'm lost mate

If you download Google Earth you can enter the 2 marks you are considering, they will show were they are and then you can use the measuring tool for distance calculation.

I use it to work out how far a fishing point is off shore.
