World File Tool - A metadata management tool for georeferenced images.

About the WorldFileTool

An interactive tool and a library to georeference images using free and open source software. A Worldfile and the KML format enable GIS programs to read georeferenced images.

Features

• Loads, edits and saves KML with its linked image
• If needed, rotates an image to be north aligned and saves it back
• Supports following graphic file formats: jpg, tiff, png, gif
• Imports and exports a Worldfile with its corresponding image

Usage

Prepare the image. In order to minimize the system strain, keep the image size smaller than 2000 x 2000 pixels.

1. Open Google Earth, use "Add Image Overlay", save it and export it as .kml in a local directory.
2. Start WorldFileTool, import KML and export it either again KML or as world file.
3. Done.

Now you can use the image e.g. in GIS tools like UMN Mapserver (based on the world file) or in IndoorWPS Locator (based on the KML).
