What value do points east of the Prime Meridian have?

Points east of the Prime Meridian have a positive value. The Prime Meridian, located at 0 degrees longitude, serves as the reference line for measuring longitude across the globe. As you move eastward from this line, the longitude values increase, indicating a positive value.

This system is integral to geographic coordinate systems, where locations are defined by their latitude and longitude. Longitudes to the east of the Prime Meridian are recorded as positive degrees, ranging up to 180 degrees. This distinction allows for easy identification of positions on the Earth's surface in relation to this established reference point.

Understanding this context is essential in GIS applications, as accurate coordinate systems are fundamental for mapping, spatial analysis, and navigation tasks in various domains, including urban planning, environmental management, and resource allocation.
