    I Why on Earth's surface, longitudinal or merediance lines are perpendicular to equatorial line?

    I think its a defination to have infinite longitudnal lines , if line are not perpendicular than the infinite point will not add up to give the circumferance of equator, please help

    Shortest Distance Between Two Latitude/Longitude Coordinates

    Homework Statement We need to find the shortest distance between two given cities. For this I'll use Bangkok, Thailand (13°N, 100°E) and Havana, Cuba (23°N, 82°W ). Earth is assumed to be perfectly spherical with a radius of 6.4x106m. These aren't the places we were given but the coordinates...

    Calculating the latitude/longitude from known distance

    For a small distance (in the range of 10's of metres) how can I calculate the latitude/longitude of a point if I know the distance in ΔN and ΔE from a known latitude/longitude using the 'flat earth' assumption? Thanks in advance :)
