GPS to local coordinate transformation

[JulianHeinz]

Hi!

My aim is to transform GPS coordinates (WGS84) into a local, cartesian coordinate system, using 6 ground control points (GCP). I know the local and global coordinates of the GCPs.

Input: GPS coordinates (latitude, longitude) + 6 ground control points

Output: coordinates of GPS points in local system

According to section 5.4 of this website I have to use a affine, or polynomial transformation.

Does anybody know a different/better method?

Is there a VI, which does affine, or polynomial transformations? Or which can determine the necessary parameters?

Cheers,

Julian

Hi Julian,

it seems there are no ready to use VIs for that. So you would have to program it yourself.

Here are two other forum posts that might help you on the way: here and here.

Hope that helps.
