How many miles apart are longitudinal lines

Each degree of latitude is approximately 69 miles kilometers apart. The range varies due to the earth's slightly ellipsoid shape from A degree of longitude is widest at the equator at Note that the original site about. Sign up to join this community.

A tenth of a minute or tenth of a nautical mile is about feet or meters.

This is the level of accuracy used in this course. There's no need to attach the prefixes "lat" and "long" or "L" or "Lo" although you may do so.

The descriptors N S, E or W indicate the co-ordinates as latitude or longitude. A nautical mile is 6, For most calculations, 6, feet is close enough. One minute of latitude equals one nautical mile and degrees of latitude are 60 nm apart. The distance between degrees of longitude isn't constant because they converge towards the poles. This is why it begins at zero and finishes at longitudes.

Now, at mile out that point would be Each degree of latitude is approximately 69 miles kilometers apart. The range varies due to the earth's slightly ellipsoid shape from One minute of latitude equals one nautical mile and degrees of latitude are 60 nm apart.

The distance between degrees of longitude isn't constant because they converge towards the poles. The haversine formula determines the great-circle distance between two points on a sphere given their longitudes and latitudes. Important in navigation, it is a special case of a more general formula in spherical trigonometry, the law of haversines , that relates the sides and angles of spherical triangles. Parallels are another name for lines of latitude. You will see that these lines do not converge, or come together, anywhere on the globe.

We call these parallels because they are always an equal distance apart. The first parallel is the equator. One degree of longitude will be 60 times 1, meters times the cosine of the latitude. For example, I live near Oslo in Norway at latitude 60 north and cosine 60 is exactly 0. It means that, where I live, one minute of longitude is half that of latitude ; 0. Apply Filter. Do all USGS 7. Historical Topographic Map Collection : Through time, policies have changed regarding whether or not a full UTM grid would appear on the 7.

Beginning in the mid s, the grid was indicated by blue ticks around the map at 1,meter spacing. In , the ticks were replaced with a full-line black What does the term UTM mean?

UTM is the acronym for Universal Transverse Mercator, a plane coordinate grid system named for the map projection on which it is based Transverse Mercator. The UTM system consists of 60 zones, each 6-degrees of longitude in width.

The zones are numbered , beginning at degrees longitude and increasing to the east. The military uses their Changes to UTM values are generally larger, around meters, How are different map projections used?

The method used to portray a part of the spherical Earth on a flat surface, whether a paper map or a computer screen, is called a map projection. No flat map can rival a globe in truly representing the surface of the entire Earth, so every flat map misrepresents the surface of the Earth in some way. A flat map can show one or more--but never all Filter Total Items: 4.
