Degrees of latitude are parallel so the distance between each degree remains almost constant but since degrees of longitude are farthest apart at the equator and converge at the poles, their distance varies greatly. 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.

The distance between degrees of longitude has great variation because they are farthest apart at the equator and coverage at the poles. A degree of longitude is widest at the equator with a distance of Longitude gradually come closer to zero as they meet at the poles. How do we know the distance between one point to another?

If we are given the coordinates of the two places in latitude and longitude for the calculation of the distance between them. It is easy to calculate the distance between two places if their coordinates are simple or round figure, but what if the coordinates are in decimal form then it is not easy to calculate. For that matter, the 'haversine' formula plays important role while calculating the distance between two places but unless you are a whiz at trigonometry. Science Explorer.

Survey Manual. The distances vary. A degree, minute, or second of latitude remains fairly constant from the equator to the poles; however a degree, minute, or second of longitude can vary greatly as one approaches the poles and the meridians converge. At 38 degrees North latitude which passes through Stockton California and Charlottesville Virginia :.

Building on the success of years of mapping, the U. US Topo maps are designed to be used like the traditional 7. Geological Survey is so well known. However, in contrast to paper Interpreting the colored lines, areas, and other symbols is the first step in using topographic maps.

Features are shown as points, lines, or areas, depending on their size and extent. For example, individual houses may be shown as small black squares. For larger buildings, the actual shapes are mapped. Latitude is the measurement of distance north or south of the Equator. It is measured with imaginary lines that form circles around the Earth east-west, parallel to the Equator. These lines are known as parallel s. A circle of latitude is an imaginary ring linking all points sharing a parallel.

The Equator is the line of 0 degrees latitude. Each parallel measures one degree north or south of the Equator, with 90 degrees north of the Equator and 90 degrees south of the Equator. Like the poles, some circles of latitude are named.

The tropics are important geographic locations that mark the northernmost and southernmost latitudes where the sun can be seen directly overhead during a solstice.

One degree of latitude, called an arc degree, covers about kilometers 69 miles. Because of the Earth's curvature , the farther the circles are from the Equator, the smaller they are.

At the North and South Poles, arcdegrees are simply points. Degrees of latitude are divided into 60 minutes. To be even more precise, those minutes are divided into 60 seconds.

One minute of latitude covers about 1. Using seconds of latitude, global positioning system GPS devices can pinpoint schools, houses, even rooms in either of these towns. Similar to latitude, the corresponding measurement of distance around the Earth is called longitude.
