Abstract: 研究了基于误差模型包络点的概率算法,并与基于随机线元法平面的概率算法进行了比较。实例计算与可视化分析发现,两种概率算法对应的概率计算值近似,Tepdem及其边界包络线一致,且前者适用于随机线元,而后者更具有通用性。
A probability algorithm based on the envelop points of the equivalent probability density error model(marked as Tepdem) is put forward,then the probability algorithm based on the normal plane of the random line segment is compared with the former.A case study is conducted and the results are visualized and analyzed.It is discovered that Tepdem and its corresponding boundary envelop as well as the probability calculation value are same under both of the probability algorithms,and the former is suitable for the random linear segment while the latter is more general for the probability calculation of the linear entity in vector GIS.
