<P> Scale is unity on the equator (for a non-secant projection). Therefore, interpreting ruler measurements on the equator is simple: </P> <Dl> <Dd> True distance = ruler distance / RF (equator) </Dd> </Dl> <Dd> True distance = ruler distance / RF (equator) </Dd> <P> For the above model, with RF = 1 / 300M, 1 cm corresponds to 3,000 km . </P>

Where does the mercator projection show the least distortion
