Latitude FAQs:


Q: Is latitude a geographic coordinate that specifies the north–south position of a point on the Earth's surface?

A: Yes.

Q: Are latitudes not used in this way?

A: Yes, they are used only as intermediate constructs in map projections of the reference ellipsoid to the plane or in calculations of geodesics on the ellipsoid.

Q: Is latitude an angle which ranges from 0° at the Equator to 90° at the poles?

A: Yes.

Q: Is latitude conventionally denoted by ψ : it is used in the development of the ellipsoidal versions of the normal Mercator projection and the Transverse Mercator projection?

A: Yes.

Q: Is latitude the greater?

A: Yes.

Q: Is latitude used together with longitude to specify the precise location of features on the surface of the Earth?

A: Yes.

Q: Is latitude 1.853 km or 1.151 miles?

A: Yes, and this distance was formerly used as the basis of the nautical mile.

Q: Is latitude also of great importance in the construction of the Transverse Mercator projection?

A: Yes.

Q: Are latitudes equal at the equator and at the poles but at other latitudes they differ by a few minutes of arc?

A: Yes.

Q: Is latitude defined with respect to an ellipsoid?

A: Yes, and the position of a given point is different on each ellipsoid: one cannot exactly specify the latitude and longitude of a geographical feature without specifying the ellipsoid used.

Q: Are latitudes given by replacing the limits of the integral by the latitudes concerned?

A: Yes.

Q: Is latitude the Equidistant conic projection?

A: Yes.

Q: Is latitude used without qualification?

A: Yes.

Q: Is latitude the Albers equal-area conic projection?

A: Yes.

Q: Is latitude calculated from angles measured between the zenith and stars whose declination is accurately known?

A: Yes.

Q: Is latitude not used in the theory of map projections?

A: Yes.

Q: Is latitude the angle between the equatorial plane and the radius from the centre to a point on the surface?

A: Yes.

Q: Is latitude zero at the equator but rapidly diverges from the geodetic latitude?

A: Yes, and tending to infinity at the poles.

Q: Are latitudes used in this way: the geodetic?

A: Yes, and geocentric and reduced latitudes are used in geodetic coordinates, spherical polar coordinates and ellipsoidal coordinates respectively.
