JTS拓扑结构程序组是一个通过使用明确的精度模型和健壮的几何算法来执行空间数据操作的Java应用编程孔。JTS是用来对可以支持空间数据集的确认、处理、综合及质疑的应用程序进行改善。这篇文献就是对在JTS拓扑程序组中执行的类、方法与算法进行说明-JTS Topology program group is defined through the use of a precision model and robust geometric algorithm to implement the spatial data of the Java application programming operation hole. JTS can be used to support the recognition of spatial data sets, processing, and querying of integrated applications to improve the situation. This literature is JTS Topology program group in the implementation of the class, method and algorithm descr iption
