these are the imaginary lines to check the gmt and location of a place
Latitude and longitude are angles that describe the location of a point on the Earth's surface. Longitudes range from zero to 180 degrees east or west. Latitudes range from zero to 90 degrees north or south. There are no official 'lines'. Some maps or globes have some lines printed on them to show where a few latitudes and longitudes are, and other maps and globes have no lines at all printed on them. I have mapping software that can print 324,000 latitude lines and 648,000 longitude lines if I want them, but I have never needed them yet.
There is no official set of "lines". Some globes and maps have more lines, spaced closer together. Some globes and maps have fewer lines, spaced farther apart. Some globes and maps have no lines at all. We have no way of knowing how many latitudes and longitudes are marked on the map that you're looking at today, and the next one you see may be marked at a different interval.
The horizontal lines are called latitudes and the vertical lines are called longitudes.

It is to do with the scale used on the maps and globes.
Some maps and globes ... such as those with a line printed every 15° of latitude ... have lines marked at 45° north and 45° south. Some maps and globes ... such as those with a line printed every 10° of latitude ... don't. Some maps and globes have no lines printed on them at all.
The network of latitudes and longitudes refers to a system of geographical coordinates that are used to pinpoint locations on the Earth's surface. Latitudes are horizontal lines that measure the distance north or south of the equator, whereas longitudes are vertical lines that measure the distance east or west of the prime meridian. Together, these coordinates provide a precise way to identify any place on the planet.
Globes usually depict reality. Maps usually have some distortion to them.
Switzerland covers the range of longitude from 5.95° to 10.48° East. Every longitude in that range traverses Switzerland. Some maps and globes include some lines to help you estimate longitudes, and some don't. Where you see lines, don't get the idea that those are the only longitudes there are.
Map are projections in a systematic transformation of the latitudes and longitudes of the locations on the surface of a sphere. Map projections distort the surface in a little bi, depending on the purpose of the map.
Globes and maps help you see our geography in an easy way. Whether you are traveling, studying, or just curious, maps and globes can show you oceans, cities, states, countries, and continents.
The lines don't measure anything, any more than the marks on a ruler do. Latitude and longitude are angles on the Earth's surface, measured between zero- references and the location you're trying to find or describe. Some maps and globes have some latitudes and longitudes marked on them, to help you estimate the angles. Just like the marks on a ruler.
