The ArchEd Program is a tool for drawing Harris matrices which are used in archaeology. Beside its ability to edit such drawings it also contains an automatic drawing feature which redraws a given graph nicely. A similar program was developed at the Amt für Bodendenkmalpflege in Bonn in 1990. While this older program runs on DOS - systems and uses the keyboard as input device, ArchEd runs with Win2000, XP or WinNT and can also use a mouse as input device. The new ArchEd version offers an additionally export format dxf. This format allows you to export the harris matrix into AutoCad.
