This is just like the hours on our clocks and goes back to the Babylonians who worked with a base 60 number system! One of the issues with DMS is that you will see them expressed in a variety of ways. This includes:. The last format is the most troublesome as when I first saw it, I thought the data was in UTM or another projected system.
I then quickly converted the data to DD. Computer software will convert coordinates from DMS to DD on a regular basis without us even knowing it is happening. However, it's good to know the equation and I routinely see spreadsheets of data in DMS and I can quickly convert the data to DD because I know the following information.
Converting between DD and DMS is now easy with the one addition that we need to remember that latitudes in the southern hemisphere are negative while longitudes in the western hemisphere where most of the US is are negative. We almost always need spatial data to be in Decimal Degrees in order to work with it in a computer.

Location is the position of a particular point on the surface of the Earth. Locale is the physical setting for relationships between people, such as the South of France or the Smoky Mountains.
Finally, a sense of place is the emotions someone attaches to an area based on their experiences. Place can be applied at any scale and does not necessarily have to be fixed in either time or space.
Additionally, due to globalization, place can change over time as its physical setting and cultures are influenced by new ideas or technologies. Learn more about the physical and human characteristics of place with this curated resource collection. Lines of latitude and longitude help us navigate and describe the Earth. Explore them with MapMaker, National Geographic's classroom interactive mapping tool.
Students look at lines of latitude and longitude on United States and world maps, discuss why these lines are helpful, and identify landmarks with similar latitude and longitude.

Encyclopedic Entry Vocabulary. Straddling the Equator in Ecuador. Any given location can be described in terms of degrees, minutes, and seconds of longitude and latitude. Degrees of latitude are parallel so, for the most part, the distance between each degree remains constant.
However, the Earth is slightly elliptical in shape and that creates a small variation between the degrees as we work our way from the equator to the north and south poles. This is rather convenient when you want to know how far it is between each degree, no matter where you are on Earth.
For example, if we were at 40 degrees north, degrees west, we would be on the Nebraska-Kansas border. If we were to go directly north to 41 degrees north, degrees west, we would have traveled about 69 miles and would now be near Interstate Unlike latitude, the distance between degrees of longitude varies greatly depending upon your location on the planet.
They are farthest apart at the equator and converge at the poles. What if you are given two coordinates for latitude and longitude and you need to know how far it is between the two locations?
You could use what is known as a haversine formula to calculate the distance — but unless you are a whiz at trigonometry, it is not easy. Luckily, in today's digital world, computers can do the math for us. Keep in mind that you can also find the precise latitude and longitude of a location using a map application. In Google Maps, for example, you can simply click on a location and a pop-up window will give latitude and longitude data to a millionth of a degree.
Similarly, if you right-click on a location in MapQuest you will get the latitude and longitude data. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. Create a personalised content profile. Measure ad performance.
