hi all i have read the article about reverse geocoding, very intersing of course ..

but i don't have fully understood some math involved in those algorithms:

- what about the expression 1\60\1852 ? (distance in meter)*(1/1852) = distance in sea miles...and what about the multiplication for 1/60, what does it mean ?

- offset for startingLongitude= radius*cos(angle) / cos( startingLongitude in radius)... what about the mening of the division for:

cos( startingLongitude in radius) ?

i hope you can help me ...

thanks
