A cartographic illustration of america that features depictions of longitudinal strains affords a visible framework for understanding geographic location and measurement. These strains, also referred to as meridians, run vertically from the North Pole to the South Pole, intersecting the Equator at proper angles. They supply a foundation for calculating distances east and west of the Prime Meridian, which passes by Greenwich, England. For example, a particular level inside the U.S. may be exactly positioned by its intersection with a corresponding line of latitude.
The inclusion of those meridians on a United States chart is essential for navigation, surveying, and geographic info programs (GIS). They supply a standardized grid system that permits for correct dedication of place and the calculation of distances. Traditionally, these grids had been important for maritime navigation and land surveying. Right now, the strains stay elementary to purposes starting from aviation to mapping software program and useful resource administration.
