Abstract: Abstract: In the field of urban planning, vector is very important to use remote sensing data. Through the analysis the characteristics of raster and vector data, and complex mathematical morphology and combining with the wavelet analysis, boundary processing and amending work, a better vector map can be gained with different types of land using. And at same time, it improve the veracity rationality and science of urban planning.

摘要： 在城市规划中，矢量化是遥感数据有效利用的重要一步。本文针对栅格和矢量数据的特点，通过分析并改进综合数字形态学的算法，同时结合小波分析技术，边界处理和修编工作，能够较准确地提出影像数据中的各类用地，得到比较好的矢量化效果。同时提高了规划的准确性、合理性和科学性。
