I need to calculate lat and long for other point. Given one lat long and bearing.

How to apply Vincenty's formulae in Matlab. http://www.geomidpoint.com/destination/

[Manoj Pai]

Consider one point is 12.9435584 77.5620174 with bearing 0 deg and distance 100 m I need to calculate the other lat and long.

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.
