Most useful information for coordinates I have been using for geocaching all these years. Thank you. Can you please tell me which is most commonly used? Students often confuse latitude and longitude. Think of a ladder it goes up and down , latitude goes north and south. A longitude of degrees 45 minutes 0 seconds would be Your email address will not be published. Skip to content. Thank you!

How many digits are in a coordinate? What is the range of longitude and latitude? How accurate are geographic coordinates? How do I find accurate coordinates? What do minutes and seconds mean in coordinates? How do you find longitude and latitude? What is 1 minute of latitude? What are Geohash coordinates? What is UTM format? How is GeoHash calculated? How big is a GeoHash? How many bytes is a GPS coordinate? What is the distance between two lines of latitude?
What is degree minutes and seconds? Degrees for DMS are divided into 60 minutes and then each minute is divided into 60 seconds. 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.
