The paper considers and classifies the possible ways for construction of technology to convert document images into a geographic information system or CAD representation. Three basic document types are considered. The image types on every step of the interpretation technology are extracted and described. The different variants of the technology are considered depending on the type of an initial document and algorithms used. The classification of eleven known in literature technologies is given. Our experience in the realization of technology variants is shown.
