本文提出了一种快速有效的算法来处理由纸质地图到数字信息的转换所产生的均匀传播畸变。由于结调整、边缘匹配和线调整，这些变形发生在块边界。数据来源是来自相邻扫描页的矢量化地图，不一定具有相同的比额或相同的精度，这将成为未来地理信息系统数据库的一部分。该算法有四个阶段，类似于肥皂泡的扩散，受到多边形环的限制，改变其形状和大小。给出了一个示例来说明所提出的方法。
This paper presents a fast and efficient algorithm to homogeneously spread distortions generated by the conversion of paper maps to digital information. These distortions occur at the block borders as a result of junction adjustment, edge matching, and line adjustment. The sources of data are vectorized maps from adjacent scanned sheets, not necessarily of the same scale or with the same accuracy, which will be part of a future geographical information system (GIS) database. The algorithm has four stages, and resembles the spreading of soap bubbles limited by a polygonal ring changing its shape and size. An example illustrating the proposed procedure is given.
