The Image Digitizing System

Abstract

The conversion of mapping technology in the DOD community from analog- to digital-based technology, which started in the 1980's required precise equipment to convert aerial photographs to digital data (pixels). These are referred to as image scanners or digitizers. This paper describes the recent development of a precise image scanner by the Topographic Engineering Center (TEC) (formerly ETL). A contractor successfully developed this scanner, called the Image Digitizing System (IDS). This paper describes the general design and operation of the system, and many of its unique characteristics. The paper also describes several test results that verify the high-geometric and high- photometric characteristics of the IDS.
