Latitude, Longitude, and Coordinate System Grids<\/h3>\n\n\n\n

Here’s how you can remember latitude and longitude:<\/p>\n\n\n\n

Latitude<\/strong> lines run east-west and are parallel to each other but measure north-north. So if you go north, latitude values increase. Finally, latitude values (Y-values) range between -90 and +90 degrees.<\/p>\n\n\n\n

But longitude<\/strong> lines run north-south and measure east-west. They converge at the poles. And its X-coordinates are between -180 and +180 degrees.<\/p>\n\n\n\n

Latitude and longitude coordinates make up our geographic coordinate system<\/strong>.<\/p>\n<\/div><\/div>\n\n\n\n

You can give any location on Earth latitude and longitude coordinates.<\/p>\n\n\n\n

The field of study that measures the shape and size of the Earth is geodesy<\/a>. Geodesists use coordinate reference systems such as WGS84<\/a>, NAD27<\/a>, and NAD83. In each coordinate system, geodesists use mathematics to give each position on Earth a unique coordinate.<\/p>\n\n\n\n

A geographic coordinate system defines two-dimensional coordinates based on the Earth’s surface. It has an angular unit of measure, prime meridian<\/a>, and datum (which contains the spheroid).<\/p>\n\n\n
