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

This is a new question. Starting a new question will get you the best answer, and will be the most useful to other people in the future searching for the same information.
