在研究栅格图像直方图均衡化算法的基础上，提出了矢量图形直方图均衡化算法，并在MAPGIS 平台上实现了等值填充图的自动均衡化软件功能，能够根据不同的成图数据和等值层数，自动完成等值区分割和层值计算，并将层值自动导入到 MAPGIS DTM 分析模块中完成图形绘制，大大提高了成图质量和效率。实践证明，矢量图形直方图均衡化算法具有良好的应用效果。

Based on the study of histogram equalization algorithm for grid image,the histogram equalization algorithm for vector graphics is designed and the interface software of automatic histogram equalization on the MAPGIS platform is achieved. According to the different vector data and contour number,it can cut apart equivalence region and calculate level value automat-ically,and then can import the level values into MAPGIS DTM analysis module to complete graphics rendering.The quality and efficiency of mapping can be greatly improved.Practice has proved that it has good application effect.
