Zero longitude / Zero latitude is a point offshore of west Africa in the Gulf of Guinea,
about 380 miles south of Accra, Ghana.
Altitude is typically measured relative to Mean Sea Level. Since your point is well out
in the open ocean, it's probably best to simply say that zero altitude at that spot is
the long-term average of the water's surface there.
The altitude at which the celestial equator intersects your local meridian is the complementof your latitude, i.e. the difference between your latitude and 90 degrees.On the equator: Your latitude is zero. (90 - 0) = 90. Celestial equator passes overhead.At the pole: Your latitude is 90. (90 - 90) = 0. Celestial equator coincides with the horizon.In New Orleans, Louisiana, or Durban, South Africa: Your latitude is 30. (90 - 30) = 60.Celestial equator intersects local meridian at 60 degrees above the horizon.
latitude is how north or south a place is from the equator. altitude is how high you are from earth's surface
for math
Albania is at higher altitude
If the altitude of Polaris is 44 degrees, this means that the observer's latitude is also 44 degrees north. This is because Polaris, the North Star, is positioned nearly directly above the North Pole, and its altitude corresponds to the observer's latitude in the Northern Hemisphere. Therefore, an altitude of 44 degrees indicates a geographic location at 44 degrees north latitude.

Every point on the equator meets that requirement.
the altitude of polaris is same as the latitude of your location assuming that you are in the northern hemisphere
latitude is how north or south a place is from the equator. altitude is how high you are from earth's surface
If Polaris appears 60° above the northern horizon, then you are pretty near 60° north latitude. If you're on the equator ... 0° north latitude ... then Polaris is on the horizon ... 0° altitude. If you're at the north pole ... 90° north latitude ... then Polaris is over your head ... 90° altitude. The altitude above the northern horizon at which Polaris appears is nearly identical to your north latitude. ================================================= The difference (error) between Polaris and the real North Celestial Pole is about 0.7 degree. Not good enough for precise navigation or surveying, but just fine for directions when you're hiking.
The Nile River is very long, so it covers a huge range of altitude and latitude.
for math
The angular altitude of the North Star, or Polaris, corresponds to your latitude in the Northern Hemisphere. For example, if you are at a latitude of 40 degrees north, Polaris will be approximately 40 degrees above the northern horizon. Conversely, at the equator, Polaris would be at the horizon (0 degrees altitude), and it is not visible in the Southern Hemisphere. Thus, the angular altitude varies directly with your geographic location.
If the altitude of Polaris is 43 degrees above the northern horizon, then the observer is located somewhere within roughly 1/2 degree of 43 degrees north latitude.
Albania is at higher altitude
Yes it does. The higher the altitude, the cooler the temperature in general.
If the altitude of Polaris is 44 degrees, this means that the observer's latitude is also 44 degrees north. This is because Polaris, the North Star, is positioned nearly directly above the North Pole, and its altitude corresponds to the observer's latitude in the Northern Hemisphere. Therefore, an altitude of 44 degrees indicates a geographic location at 44 degrees north latitude.
