Longitude and latitude are the combination of longitude and latitude to form a coordinate system. It is a spherical coordinate system that uses the sphere of three-dimensional space to define the space on the earth, and can mark any position on the earth. Latitude and longitude are the auxiliary lines assumed by human beings for the convenience of measurement, which are defined as the trajectory formed by a point on the earth’s surface along with the earth’s rotation.

Many tattoo people will have longitude and latitude coordinates tattoo. These coordinates are generally more emotional cities for tattoos, such as hometown or city where they have been for a long time. Today we have collected a lot of coordinate tattoos. I hope these tattoos can give you some inspiration.
