Taking the uncertainty of line segment as an example, this paper discusses the evaluating methods of statistic entropy, fuzziness entropy, and hybrid entropy...
以GIS中线元不确定性为例，讨论了线元不确定性的统计熵、模糊熵和混合熵估计方法，并针对特例给出了线元不确定性的熵带分布。
The so-called maximum entropy method is to find a model keep to the maximum entropy principle, which means select the statistic model that has the maximum entropy and satisfy all the constrains.
所谓最大熵方法就是遵循最大熵原则建模，也就是选择这样的一个统计概率模型：在满足约束的模型中选择熵最大的那个。
Then according to statistic analysis including interband correlation and entropy, etc. the selection of the optimal bands of TM was discussed.
然后，通过波段相关性和信息熵值分析，选取最佳波段。
