#44220 - Distance Calculations using Lat/Long
Hello,
I'm trying to implement distance calculation formulae on At89c51 using Latitude and longitude.
While most formulae available on internet and books a lot of multiplications, divisions and even trigonometric functions.
These functions are difficult to implement on the controller like this one.
I found an approximate formulae on net.
d=sqrt(x*x + y*y)
where x=69.1*(lat2-lat1)
y=53*(long2-long1)
It is simple and much easier to implement but the problem is that this formula is not providing much accuracy as well as it gives answers which are far beyond the estimated one.
Anyone help me in this regard as soon as possible.
