The difficulty in retrieval of visual information in engineering technical drawings needed for decision-making is an area of major concern. Current methods of retrieval do not satisfy the demand for rapid and precise location of information contained in large sets of drawings. This paper presents a conceptual model, a classification scheme and a prototype of an information retrieval system (IRS) for engineering technical drawings which addresses this problem using techniques of analysis and processing of images. The system integrates concepts of information science, computer science and engineering to improve retrieval of technical drawings which can impact positively on services and decision making in areas such as infrastructure (sanitation, energy and roads), security, health and education.
