by using coordinate geometry you can find the position of a place in earth by using the pictures taken by satellites.
Every point on earth has both a latitude coordinate and a longitude coordinate. That's how you tell people where the point is, even if they're not there.
They project the surface of a sphere (the Earth) using a projection. Often the latitudes and longitudes are mapped onto the coordinate plane for small area but such projections distort shapes when mapping larger areas.
To locate points on the Earth's surface, we can use either rectangular coordinate system or geographic coordinate system.4digit or 6 digit reference systems are under rectangular ( projected) system.Their difference lies in assigning Easting and Northing. 4 digit RS uses 2 Easting numbers and 2Northing numbers to show the location of points where as 6 digit uses 3 Easting and 3 Northing numbers. If there is any Hesitation please Well come.
On a map that shows only a small part of the Earth's surface, the coordinate gridlooks like Cartesian " X and Y " coordinates. But as the map shows more and moreof the Earth, it starts to become apparent that the "lines" of latitude and longitudeactually represent polar coordinates on a sphere of constant radius.On a map that's sufficiently accurate, your first clue is this: Carefully measure thedistance between two of the 'vertical' lines, at the bottom of the map, and thenmeasure the distance between the same two lines at the top of the map. The twomeasurements are slightly different, because on a map of the full Earth, the 'vertical'lines all meet, at the north and south poles.
all of them
Places on Earth can be located using a coordinate system, such as latitude and longitude. Latitude measures a location's distance north or south of the equator, while longitude measures its distance east or west of the Prime Meridian. By combining these coordinates, any point on Earth's surface can be pinpointed with accuracy.
In the horizon coordinate system, azimuth is similar to longitude in the geographic coordinate system. Azimuth represents the direction of an object in degrees along the horizon, similar to how longitude represents the east-west position on Earth's surface.
grid system
Geographers use a coordinate system based on latitude and longitude to describe the precise location of places on Earth. They also use descriptors like relative location (e.g., north of, to the left of) and regions (e.g., the Midwest, the tropics) to provide context for where things are located in relation to other places.
Geography is the study of the Earth's surface features and processes. In geography, it is important to locate these features on the surface of the planet. To do this you have to have some sort of coordinate system. Latitude and longitude are this system they enable maps of earth to be made and for airplanes and ships to get to places on the planet.
The rectangular coordinate system is the basis for how we find locations on a map, for example (even though the earth is actually a sphere, this was a basis). I would say it is rather important.
The geographic coordinate system
The oldest systematic method of location is based upon the geographic coordinate system, which uses latitude and longitude to pinpoint specific locations on Earth.
They are the axes of the coordinate system that is used for places on the earth's surface. Every point on the earth's surface is a certain number of degrees east or west of the prime meridian (its longitude) and a certain number of degrees north or south of the equator (its latitude).
The buoy located at O Latitude 0 Longitude is known as the "Zero Buoy" or the "Equator Buoy." It marks the precise location of the Equator, where the Earth's latitude is 0 degrees.
In terms of geography, an absolute location is a point on the earth's surface expressed by a coordinate system such as latitude and longitude.
