Image tracing

Raster to Vector software and hardware technology for converting Raster graphics to Vector graphics is used by a number of fields, most notable in conjunction with CAD and GIS systems. For example: Drawings that only exist in physical form (blueprints, plots of lost files, etc.) can be converted into CAD files using a procedure called "Paper-to-CAD conversion" or drawing conversion, involving scanning and vectorization, or digitization.
