Abstract

Today, with advances and development of computer technology, many firms and organizations which practice map preparation have turned to conversion of manual system (manual cartography) to computer system (digital cartography). Currently all stages of manual cartography are carried out using computers, which leads to increase of the speed of cartographic operation, achievement of top quality at stages of work and reduction of map preparation costs.
In this paper, the Raster and Vector information in creation of cartographic images as well as advantages and disadvantages of these images and their method of processing are examined.
