[scikit-image] Techniques for Aligning images to GIS data

[Vighnesh Birodkar]

Hello

Answering Michael's questions

The images I have are already ortho rectified. I don't want to co register
2 images. I want to register an image with some GIS data (like Open Street
Maps). So in that sense it is the problem of registering an image with a
vector of features.

Thanks for the pointer to the talk Juan.

Thanks
Vighnesh
