This web app will perform a coordinate transformation (translation, scaling, and rotation) on raster image files georeferenced with ESRI world files. The webapp will read the source world files (*.tfw,*.pgw,etc.) and apply the user-defined transformation settings. The resultant world file values will be listed and labeled with the world file name. Just copy the results and paste into the associated world file with any text editor.

1. Set the transformation parameters in the sidebar.
2. Then drag and drop the world files (*.tfw,*.pgw,*.jpw,etc.) into the dashed box below or click the button to select the world files.
