Final answer:
The US Geological Survey has established official datums for latitude, longitude, and elevation, which are essential for accurate geographic positioning and mapping on the Earth.
Step-by-step explanation:
The US Geological Survey (USGS) has established official datums related to latitude, longitude, and elevation.
These datums are crucial for accurately describing any location on Earth with a specific address of degrees north or south and east or west. Latitude and longitude form part of a grid pattern known as the graticule, essential for navigational purposes, such as by pilots or ship captains specifying positions on a map.
Meanwhile, elevation datum ensures consistent measurement of altitude above sea level for various purposes, including mapping and construction.
