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...
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 :)
