The GGU-STRATIG programme allows the presentation of  bore profiles and dynamic penetration tests according to German Standard DIN 4023. Additionally, data histograms,  tables, well casings (in the classical, as well as in a simplified, very space saving, manner) and cone  penetration tests can be presented and edited. Data  input is in accordance with WINDOWS conventions and can therefore be learned almost without the use of a  user-manual. Graphic output supports the True-type fonts supplied with WINDOWS, so that an excellent layout is guaranteed. Colour output and Bitmap graphics are  supported. For refinement of graphics, DXF files may  also be imported。
