----------------------------Original message---------------------------- There are a number of packages which do this now, ranging from expensive, special purpose packages such as Laser Scan's VTRAK to Arc/Info addons like ArcScan and an AutoCAD addon called CADCore. A low-end standalone is from a company called Audre but I don't know the name of their product. Terrell R.
