Abstract

Area properties of mapping region has important impact on expressive effects of color grading symbol, which is mainly reflected in two aspects: firstly, color´s area proportion in mapping region will affect the strength of visual impact from color, which can influence maps´ clarity and comfort; secondly, area difference between different classes will affects visual perception caused by original color grading symbols, which can cause visual illusion. Based on China´s provincial area model, this paper explores how to recognize the problems caused by area difference, and provide thought of auto-adjustment of traditional color grading symbol. Then the paper realizes the method using Visual C# and Supermap Object to realize a system having the function of the auto - adjustment of the map color.
