The Matlab function reckon is what you are looking for. For plotting the track, use track1.

Here is an example for the values you gave:

   latIn=12.9435584;
   lonIn=77.5620174;
   dist = 100; %meters
   distUnits = 'm';
  % Convert input distance to earth degrees (Lat, Lon are typicaly given in degrees)
   arclen = rad2deg(dist/earthRadius(distUnits)); 

[latOut,lonOut] = reckon(latIn, lonIn,arclen,az)

results in:

latOut =

    12.944457721605922

lonOut =

    77.562017400000002

Hi Ted ,

If I have a point X1(lat1,lon1) and X2(lat2,lon2)

and I have point Y with d1 distance ( in m) from X1 and d2 from X2.

How can i get the lat and lon of point Y ?

thanks very much
