<br/>
for in that case we could enter decimal lat & long for 1 of those points & then give the azimuth & distance in km to maybe more than 5 decimal places for determining the second of those points within a similar degree of precision<br/>
<br/>
so i have to wonder if you cant simply do this calculation in reverse<br/>
<br/>
& if so then voila waorus is fait accompli<br/>
