**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.
