Converting Longitude/Latitude/Altitude to Cartesian Coords

[zeeshanzia84]

Hi,

I want to convert Longitude/Latitude/Altitude coordinates of a point to x,y,z coordinates.

Actually, I have some 3D models in Google Earth's .KMZ format; all vertices stored in GE format are in Longitude/Lat./Alt. coordinate system, and I want them in cartesian coordinates.

Thanks a lot in advance.

Hi,

Thanks for the reply. Can you please tell me the numerical values of these constants? I tried to google them, but in vain.

I will be very thankful if these values could be accurate a large number of decimal points say 15.

Actually thanks...I got it from Wikipedia.
