| 摘 要： | 针对地理国情普查底图制作过程中数据量大、时间紧、采用传统的镶嵌线生成方法费时费力等问题,提出了基于初始规划网的镶嵌线自动生成法。该方法先利用顾及面要素法和泰森多边形获得初始规划网,然后利用相关系数算法选择最优镶嵌线,最后进行接边纠正。研究表明,该方法可完全满足地理国情普查DOM制作的精度要求,且能大大提高DOM的生产效率。

Study on Method of Generating Mosaic Lines Automatically Based on the Initial Pla nning Network |

| Abstract: | Pointing at the fact that there is a large amount of data, and limited time in making base maps for geographical conditions surveying, and the traditional method of generating mosaic lines waste time and energy, this paper presents a method based on the ini-tial planning network to generate mosaic lines automatically.It firstly use the method of taking into account the surface element and thiessen polygon method to get the initial planning network, and then use the correlation coefficient algorithm to select the optimal mo-saic line, finally, edges are corrected.Studies show that this method can fully satisfy the accuracy requirement for DOM making in surveying of geographical conditions, and digital orthophoto map’s productive efficiency can been improved in a large extent. |
