Final answer:
The altitude-intercept model employs latitude and longitude to pinpoint locations on the Earth, similar to how right ascension and declination map the sky. This method is an improvement over older methods, offering global navigation standards.
Step-by-step explanation:
The altitude-intercept model is a method used to find a position on the Earth's surface by utilizing a system of spherical coordinates that includes latitude and longitude. These coordinates are akin to the cities and avenues mapped on a city plan but designed for a spherical context, enabling the pinpointing of any location on Earth. This method differs from previous positioning methods as it provides a more organized and global standard for navigation and mapping, significantly improving upon more rudimentary methods such as using landmarks or stars for orientation.
In a similar fashion to how latitude and longitude map the Earth, astronomers employ right ascension and declination to map the sky, defining positions of celestial bodies. The latitude of the North Pole and South Pole are 90 degrees North and 90 degrees South, respectively; however, at these poles, the concept of longitude becomes irrelevant as all meridians converge at these singular points, so there's no meaningful distinction between different longitudes there.
