Difference between latitudes &longitudes?
91114
Lines of latitude go around the earth from east to west and are all parallel to each other.  They tell pilots, sailors, etc. how far they are north or south of the equator and how far they are from the north or south pole.  The equator is sort of the main line of latitude.  \n\nLines of longitude go from north to south and each one passes through both the north and south pole, so they are not parallel to each other.  The main line of longitude is called the Prime Meridian and it passes through Greenwich, England.  That is also the line on the earth that is used to determine time zones.\n\nThink of a peeled grapefruit or an orange. The segments of the grapefruit are sort of like the lines of longitude.  But if you cut the grapefruit through the middle like you do if you eat it for breakfast the cut that you make is sort of like the equator, the main line of latitude.\n\nHope this helps.

The use of grid lines on maps (latitude and longitude) was first suggested by the Greek astronomer Hipparcus about 300 years before Christ. He was the first who devised a method for fixing the location of places on earth by observation of the the sun, moon and stars. He worked out the mathematics of spherical trigonometry, which allowed the results of these observations to be plotted on an earth which he knew already to be a sphere.\n\nLatitude can be found easily by measuring the height of the sun at noon. The measurement of longitude is not so simple as you need an accurate clock.

east/west.\n\nto remember, longitutde has lines that are all as "long" as each other (one pole to the other.)

A three dimensional coordinate (point in space) reads (x,y,z).\nSo, (1,2,-2) = (x,y,z) clearly implies that x=1, y=2, and \nz= -2, as you required.

I'll assume you are using paper copies of USGS maps. Maps from other countries may have varied coordinate systems, but most will have latitude and longitude along the borders of the map. You use this to determine the coordinate values for the point you are seeking. There are plastic scales made to fit 7.5 minute USGS maps and other scales, that make this quicker. Of course, if you have some mapping software, you can get the points just by putting your mouse pointer over the spot on the map you want to find. I've carried my laptop to the field just for this purpose at times, but paper doesn't ever have a dead battery. \n\nThis site shows the basic method:\nhttp://gpsscales.com/chapter2.htm

to locate a place, you need to know it's gedesic coordinates:longitude,latitude and height over MSL(mean sea level).MSL is not the same everywhere, each country decides wich level is it: it's defined after tide gauge, the average level is the MSL, tou must also know that different seas don't have the same level. \nHeight over MSL is defined by different surveying techniques: it can be GPS measurements, main levelling or geometric levelling (wich gives elevation accordingly to a height-known point).\nIf cartesians coordinates are used (X,Y,Z),it is more simple because you need to know distance from earth's center, you don't need to know sea level.

Latitude lines are placed so that they are parallel to each other- they form parallel circles around the earth.  Longitude lines, on the other hand, are not parallel- they intersect at the north and south poles.  Because they intersect at the north and south, the closer you get to the either of the poles, the shorter the distance from east to west between lines of longitude. Because latitude lines never intersect each other, the distance between them remains the same from north to south, across the globe.

infact i am not clear about you question. even though i am trying to clear your doubt. ok\nyou can specify the geographical coordinations like the following exaple.\n\nfor example if you want to specify the end point of a line in 35°45'56.8" and the distance of 25 from the start point  you can enter\n@25<35d45' 56.8"\n\nnote: no space between @ to "\n\nfor degree use d\nfor minut use '\nfor second use "

Assuming your point of origin has the coordinates of y latitude N/S and x Longitude E/W, the opposite point would be y latitude S/N (The opposite direction. If origin is north, then the opposite would be the same value south.) The Longitude is figured by subtracting 180 degrees from the origin's value, and drop the minus sign, then changing the direction from east to west, or west to east.\n\nIf this does not make sense, post a detail, and I will try to clarify.

maps.google.com\n\nCan I search the map on Google Maps using latitude and longitude coordinates?\n\nYou can search for some locations using latitude and longitude coordinates on Google Maps. An example of this can be seen here.\n\nPlease note that the functionality of coordinate searches may be limited at this time.

Eastings and Northings are UTM Coordinates (Universal Transverse Mercator). These are different from Longitude and Latitude values that are in the degree, minute, second format. \n\nI found the formulas for ALL conversions here in this .PDF (its a defense document so it is dry reading, but TONS of good info)\nhttp://earth-info.nga.mil/GandG/publications/tm8358.2/TM8358_2.pdf\n\nand the software program (free) to do the calculations.\nhttp://earth-info.nga.mil/GandG/geotrans/index.html\n\nHere is the main page with all the links on it:\nhttp://earth-info.nga.mil/GandG/coordsys/csat_pubs.html\n\nA lot of this LOOKS difficult, but it isn't really. Just take your time and read it carefully. Good luck!

Google maps. Just enter the lat-long in the search bar. Note you don't need to enter the degree, minute or seconds mark, just use spaces.

If you find the latitude of the northernmost point and the latitude of a point directly south of that you can calculate it.  Multiply the difference in degrees by 60 to get the distance in nautical miles.  Then apply the conversion factors:  1 nautical mile = 1.152 statute miles and 1 statute mile = 1.609 kilometers.  Combined, that means to multiply the difference in longitude in degrees by 111.214.  (Use degrees and decimal degrees, not minutes and seconds).\n\nYou'll be pretty close with this method even though it assumes a spherical Earth.

The country of India lies from 37 Deg North lat to 8 Deg North lat approximately 29 degrees.  And from 97 Deg East Long, to 68 Deg. East Long, or approximately 29 degrees.  The reason that the distance of north-south vs. east-west when the degrees are close to the same is that while degrees of latitude are equivalent (that is why they are called parallels) degrees of Longitude are not equivalent.  Each degree of Latitude is parallel to the equator and the poles, in a sense imagine a series of planes bisecting the earth at each line, the planes are separated by equidistant degrees.  Whereas Longitude cannot be equivalent.  Look at a globe, the lines of longitude start equidistant at the equator but as they move towards the poles in a strait line they grow closer together.  So every degree of longitude may be 1 Km distant at the equator for every degree north or south they you move along the line you slowly get closer to every other line of longitude until they all meet at the poles.

Angle measurement, which is the meaurement behind latitude and longitude (the angle being at the center of the earth) are measured in degrees to start with, but to get the measurement more precise, degrees are divided into minutes, and the minutes are divided into seconds.  (Nothing to do with time measurement, except that a degree has 60 minutes, and a minute has sixty seconds).  So 54 35' 45.6" reads 54 degrees, 35 minutes, 45.6 seconds.

use google earth and find the latitude and longitude

WGS84 is the map datum not the coordinates.  Datum is the format which the map is based on.  UTM can be converted to MGRS, DMS. or lat long?
