Research on Precision Transmission and Reproduction of Map Colors

This paper aims at map color management. The current researches of symbol library mainly focused on composition style, drawing methods and sharing mechanism, etc. Without considering the device and environment related characteristics and visual feeling features of map colors. Some errors such as color losing and color cast often happened on the transfer process between different media. Then, map visual effects were reduced and even wrong geographic information were transferred. Therefore, this paper is to solve such problems. Firstly, map color＇ s characteristics containing color range, color appearance and visual feeling are analyzed. Secondly, the present color management methods are compared and a new one in symbol library is proposed. Finally, a prototype system is designed to validate the feasibility of accurate map color transferring and reproduction.
