在分析顾及障碍空间下测算定级单元作用分的补充修正法和障碍空间阻隔法的同时,提出了阻隔线阻隔法的基本原理和实现过程,并以湛江市市区土地定级为例,验证了阻隔线阻隔法。实验结果表明,阻隔线阻隔法能够有效地解决在矢量数据表达中障碍空间下定级单元作用分计算。
The supplementary correction method and the obstacle space barrier method calculating effect value of classification parcel considering obstacle space and analyzed, and the keystone and step of the obstacle line barrier method is put forward, and an example of Zhanjiang City urban land classification is given. The results of the practical date processing show that the obstacle line barrier method is a scientific, rigorous, feasible solution.
