Before we dive into the reading of GPS coordinates, it is critical that you have a good hold close of the GPS gadget and traditional skills of the geographical lines of range and longitude. Once you remember that, reading coordinates is very easy, and you can train with online equipment.Introduction to GPSGPS stands for Global Positioning System; a gadget used for around the globe navigation and surveying. It is frequently used for pinpointing one’s actual region anyplace on the Earth’s surface and acquiring the existing time at a precise location.This is made feasible by means of the network of 24 man-made satellites, referred to as GPS satellites, which orbit above the Earth at excellent speeds and precision. Using low-powered radio waves, devices can communicate with the satellites to accurately verify one’s area on the globe.Originally a system used handiest by way of the military, the GPS device turned into available for use by means of voters almost 30 years ago. It is maintained by the U.S. Department of Defense.Latitude and LongitudeThe GPS equipment makes use of the geographical lines of range and longitude to supply coordinates for a person’s location or a area of interest. Reading and understanding GPS coordinates calls for a basic understanding of navigation employing the lines of range and longitude. Using both sets of lines adds a coordinate for the a whole lot of areas around the world.The image shows the lines of range and longitude.Lines of LatitudeLines of latitude are horizontal lines that stretch from east to west across the globe. The longest and leading line of latitude is called the Equator. The Equator is represented as 0° latitude.Moving north of the Equator, both line of latitude increases by means of 1°.
Therefore, there will be lines of latitude representing 1°, 2°, 3°, and so on up to 90°.
The photo above maximum effective exhibits the 15°, 30°, 45°, 60°, 75° and 90° lines of range above the Equator. You will be aware that the 90° line of range is represented through a dot at the North Pole.All lines of range above the Equator are indicated with the letter ‘N’ to denote north of the Equator. Therefore, we have 15°N, 30°N, 45°N, and so on.Moving south of the Equator, both line of range increases by way of 1° as well. There will be lines of range representing 1°, 2°, 3°, and so on up to 90°.
The photo above handiest reveals the 15°, 30° and 45° lines of range less than the Equator. The 90° line of latitude is represented by means of a dot at the South Pole.All lines of latitude less than the Equator is indicated with the letter ‘S’ to denote south of the Equator. Therefore, we have 15°S, 30°S, 45°S, and so on.Lines of LongitudeLines of longitude are vertical lines that stretch from the North Pole to the South Pole. The leading line of longitude is called the Prime Meridian. The Prime Meridian is represented as 0° longitude.Moving east of the Prime Meridian, both line of range increases by the use of 1°.
Therefore, there will be lines of longitude representing 1°, 2°, 3°, and so on up to 180°.
The picture above maximum effective exhibits the 20°, 40°, 60°, 80° and 90° lines of longitude east of the Prime Meridian.All lines of longitude east of the Prime Meridian are indicated with the letter ‘E’ to denote east of the Prime Meridian. Therefore, we have 15°E, 30°E, 45°E, and so on.Moving west of the Prime Meridian, each line of latitude increases by way of 1° as well. There will be lines of longitude representing 1°, 2°, 3°, and so on up to 180°.
The photo above best exhibits the 20°, 40° 60°, 80° and 90° lines of longitude west of the Prime Meridian.All lines of longitude west of the Prime Meridian are indicated with the letter ‘W’ to denote west of the Prime Meridian. Therefore, we have 15°W, 30°W, 45°W, and so on.You can view more tips on lines of latitude and longitude by the use of looking this YouTube video using the link below:Reading Geographical CoordinatesGlobal navigation makes use of lines of latitude and longitude to pinpoint a specific vicinity on the Earth’s surface. It is given as geographical coordinates.The photograph highlights a area in South AmericaThe vicinity is discovered along the line of range 10°N and along the line of longitude 70°W.
When outlining the coordinates of a place, the line of range is always given first followed by way of the line of longitude. Therefore, the coordinates of this location will be: 10°N range, 70°W longitude.The coordinates can be quite simply written as 10°N, 70°WHowever, most destinations on the Earth do now not fall along the lines of latitude or longitude, then again inside of the shapes created from the intersection of the horizontal and vertical lines. In order to correctly pinpoint a human being on the Earth’s surface, the lines of latitude and longitude are extra divided and expressed in one of the three average formats:1/ Degrees, minutes, and seconds (DMS)The space among each line of range or longitude representing 1° is divided into 60 minutes, and both minute is divided into 60 seconds. An example of this layout is:41°24’12.2″N 2°10’26.5″EThe line of latitude is read as 41 stages (41°), 24 mins (24′), 12.2 seconds (12.2”) north. The line of longitude is read as 2 stages (2°), 10 mins (10′), 26.5 seconds (12.2”) east.2/ Degrees and decimal mins (DMM)The space among each line of latitude or longitude representing 1° is divided into 60 minutes, and each minute is additional divided and expressed as decimals. An instance of this layout is:41 24.2028, 2 10.4418The line of range is read as 41 ranges (41), 24.2028 mins (24.2028) north. The coordinate for the line of latitude represents north of the Equator because it is useful.
If the number is negative, it represents south of the Equator.The line of longitude is read as 2 ranges (2), 10.4418 minutes (10.4418) east. The coordinate for the line of longitude represents east of the Prime Meridian because it is useful.
If the number is negative, it represents west of the Prime Meridian.3/ Decimal stages (DD)The area among each line of latitude or longitude representing 1° is divided and expressed as decimals. An instance of this format is:41.40338, 2.17403The line of range is read as 41.40338 levels north. The coordinate for the line of range represents north of the Equator because it is valuable.
If the number is poor, it represents south of the Equator.The line of longitude is read as 2.17403 tiers east. The coordinate for the line of longitude represents east of the Prime Meridian because it is positive.
If the number is bad, it represents west of the Prime Meridian.Reading Coordinates on Google MapsMost GPS gadgets supply coordinates in the Degrees, Minutes and Seconds (DMS) format, or most commonly the Decimal Degrees (DD) format.
The everyday Google Maps adds their coordinates in either DMS and DD formats.The image above reveals the region of the Statue of Liberty on Google Maps. The coordinates given for its area are:40° 41′ 21.4” N 74° 02′ 40.2” W (DMS)This is read as: “40 stages, 41 mins, 21.4 seconds north and 74 degrees, 2 minutes, 40.2 seconds west”40.689263 -74.044505 (DD)Just to recap, the Decimal Degree (DD) coordinates does no longer have the letters N or S to signify whether the range coordinate is above or under the Equator. Neither does it have the letters W nor E to represent whether the longitude coordinate is to the west or east of the Prime Meridian.This is performed via the use of valuable and terrible numbers. Since the latitude coordinate is advantageous, the coordinate is above the Equator. Since the longitude coordinate is poor, the coordinate is west of the Prime Meridian.Verifying GPS CoordinatesGoogle Maps is a great Internet tool for verifying the coordinates of areas of interest.Finding the Coordinates for a precise location1/ Open Google Maps at https://maps.google.com/ and find the vicinity of your place of interest.2/ Right-click the vicinity and choose “What’s here?” from the small menu that appears.3/ A small box will manifest at the bottom indicating the name of the area and the coordinates in Decimal Degree (DD) layout.Verifying the Coordinates of a precise locationOpen Google Maps at https://maps.google.com/.
There will be a search bar at the top-left corner of the page.Enter the coordinates into the search bar then press the Enter key or the Search icon. The coordinates can be in any of the three formats. Please note that the coordinates have to be entered correctly.Google Maps will imply the area of the entered coordinates with a red pin.Converting among DMS and DD formatsThere are quite a lot of gear available on the Internet that can support you in converting between the Degree, Minute and Seconds (DMS) and the Decimal Degree (DD) formats.For mathematicians willing to perform the raw calculations, you can be told how to convert from DMS to DD and vice versa.There are websites on hand that deliver quick conversion among DMS and DD. Here is a link to a website that adds either DMS and DD coordinates for any actual vicinity employing Google Maps.GPS-enabled devicesTo take skills of the pinpoint accuracy of the GPS gadget, you desire a GPS-enabled device.
