If I have these coordinates I can update the longitude and latitude to move the marker. In order to do this I need to fetch the coordinates of the location where the user clicked on the map.
Now I want to be able to replace the marker by clicking somewhere on the map. I integrated the Angular2+ Google Maps module to my Angular project ( ). Following these coordinates might even save an airplane pilot time by indicating the location where they are most likely to land or deliver aid packages.I want to do something which is probably really simple however I can't seem to figure it out. Coordinates allow engineers to plan in-depth for their work by pinpointing the best spot to construct buildings, bridges, wells, or similar structures. Coordinates can provide military forces with access to weapons or enemy personnel in the area. Knowing the coordinates of a site is valuable for military, engineering, and rescue operations. Coordinates can be used to locate any point on Earth. The point in the grid where parallels and meridians intersected the coordinate. Maps marked with parallels and meridians, creating a grid. Longitude is measured in degrees, north or south of the Equator. All meridians meet at the North and South Poles. The Earth’s curvature results in a different measurement for various degrees of longitude. However, it can vary depending on its increased distance from the Equator. For example, Paris, France, has a longitude of 2º 29′ E (2º 29′), while Brasilia, Brazil, has a longitude degree of 47º 55′ W (47º 55′).Ī degree of longitude is about 111 kilometers (69 miles) and spans widest near the Equator. The other half, the Western Hemisphere, in longitude west of the prime meridian.īreaking down degrees of longitude into 60 minutes, each minute can be split up into 60 separate seconds. Half of the world, the Eastern Hemisphere, is measured in longitude east of the prime meridian. The antimeridian is halfway around the world and is used for the International Date Line. The prime meridian is international shorthand for the Greenwich meridian, a longitudinal line universally accepted as 0 degrees of longitude. Meridians measure the degrees of longitude and meet at the North and South Poles. The Earth is divided into 360 degrees of longitude.
Longitude is relative to the Prime Meridian and is measured in longitude degrees. Like latitude, the corresponding distance measurement around the Earth is called longitude these line coordinates intersect to form various grids with different patterns. Using seconds of the degree (really seconds of latitude on Earth), a global positioning system (GPS) can pinpoint schools and address even in either of these towns. The higher the degree of latitude, the farther north or south you travel, and how taller you climb each minute/second.įor example, the latitude for Cairo, Egypt on Earth is 29° 52′ N while Cape Town, South Africa is at 33° 56′ S. Because of the Earth’s curvature, the farther the circles are from the Equator meet in smaller the circles.ĭegrees of latitude are divided into 60 minutes, and those minutes are divided into 60 seconds. One degree of latitude called an arcdegree covers about 111 kilometers (69 miles). A similar circle runs around the Earth at around 23 degrees 26 minutes 21 seconds S, marking the southernmost latitude. At 23 degrees 26 minutes 21 seconds N, it is the location on Earth that reaches the most northern latitude where the sun can be seen directly overhead on a solstice. Some circles of latitude are named, with one being the Tropic of Cancer. The Equator, for example, lies on 0-degree latitude. Latitude can range from 0 degrees to 90 degrees and is the measure of an angle used to show a location’s distance from either the Equator or the North Pole. A circle of latitude is an imaginary ring linking all points sharing a parallel. Latitude is measured in imaginary lines equal to 180 degrees, known as parallels. Latitude is the magnitude scale for its position north or south of the Equator. The latitude and longitude points are called coordinates and can be used together to locate any point on Earth. The imaginary lines of latitude and longitude intersect each other, forming a grid that covers the Earth.
