Perhaps the most commonly used world map is the Mercator projection. It was almost in use in the 15th century. The Mercator projection is an important part of maps is the imaginary lines of longitude, latitude and the miles. Mercator took the globe(地球仪) and made it flat(平的), but ...
To make a pair of GPS coordinates, you first need to understand how to read latitude and longitude lines. Together, they create GPS coordinates. To create a pair of coordinates, you first need to find the location you want to pinpoint on a globe or map. Once you have found it, draw ...
