[OSGeo-Discuss] OS-Tool for generating eww-files

[Bischof, Richard]

Hello,

I have a number of scanned aerial images in .ecw-format, which have to be georeferenced, using eww-file. 
How can I calculate the eww-file using multiple passpoints and transformation types like linear or polynomial? 
Is there any open source tool,I can use? gdal_warp doesn't seems to be used to that.

Thanks, Richard
