A Method of Geographic Information Acquirement Based on Subdivision Coloration for a Zone

Abstract

A new method for coloring Electronic map based on RGB information subdivision is proposed in this paper, which can output the RGB value for subdivision zones automatically and build the unique relationship between geographic zone and RGB value, and the position and geographic information acquirement can be achieved more easily. This method is faster than traditional GIS system when searching data from database, because it doesn't need search keywords and zone's location message anymore, simplifying the data structure, cutting down the complexity and computer source and improving the efficiency of search. The analysis of this method and experimental results demonstrate that the method is fairly efficient and convenient.
