The use of a scanner in archaeological excavation is a powerful tool for electronic documentation. A precise method to take advantage of this new hardware peripheral has been documented. There are four essential components: a camera, a portable personal computer, one handy-scanner (at least) and good software for image processing (bitmap and vector). The main advantages offered by this collection are that one obtains high metric precision, quick recording times and wide flexibility in data manipulation. A very complex structure (a knapping floor) from the archaeological excavation of Riparo Tagliente (VR), dating to the Epigravettian (late Upper Palaeolithic), was used to conduct the test. Starting with a mosaic of photographic images, it was possible to obtain the morphology of the paleosurface in an electronic format. After the automatic electronic input it is then possible to modify the shapes and qualities (thickness, colour, position . . .) of single objects like flints, bones, stones and so on. It is also possible to enhance the images with the application of filters to optimise contrast, brightness or clarity, to zoom into particular areas or to magnify a single object, and to work on different layers. The output on paper may be the partial or total restitution of the final image, or the print of a single group of objects in different formats and scale drawings. However, the main advantage is that of obtaining documentation during the excavation and building a complete database of alphanumerical, statistical and distribution data and object images.
