摘要
Abstract
The buffer construction of line object in GIS usually uses the parallel algorithm. But, when the baseline is complex, the algorithm brings about many intractable problems, when the baseline is a line group, there are more problems to solve. By splitting baseline into segments, it constructs buffers of segments respectively, and then combines them, those complicate cases can be avoided. In order to improve efficiency, it constructs topological relation between point, line, polygon and extensively uses vector algebra for computing, while it discusses some special cases.关键词
