Scanners: Hand held scanners show promise as inexpensive and portable data acquisition devices. Desk top scanners have similar capabilities as the hand held models, with the obvious exception that they can scan larger areas of copy. Desk top scanners are not subject to the variables of the hand manipulated device, but neither do they allow the same application flexibility, nor are they as portable. A scanned document database consists of bit mapped digital images of the source documents. In many applications, an image of a source document stored in a graphic file format and retrieved through a reference index may fulfill data acquisition and storage requirements. Graphic files and component elements can be processed using a raster type graphic editors such as TIPS or PC Paintbrush. Graphic elements can also be converted by software to a vector format that is compatible with computer aided design (CADD) systems.
