DireKtion is a satellite navigation project based on data from OpenStreetMap.org. It aims to provide a free (not just as in beer) satellite navigation solution for any vehicle/person that can carry a Linux device. It is able to calculate a route between any two points on a map, and displays directions for traveling between them.
YAGF is a graphical frontend for the cuneiform and tesseract OCR tools. It lets you open already scanned image files or obtain new images via XSane (scanning results are automatically passed to YAGF). Once you have a scanned image you can prepare it for recognition, select particular image areas for recognition, set the recognition language and so on. Recognized text is displayed in an editor window where it can be spell-checked, corrected, saved to disk, or copied to clipboard. YAGF also provides some facilities for a multi-page recognition.
