## README

## JTS简介

JTS提供了一套操作几何向量的java类库<br>
早期版本 com.vividsolutions，已废弃不在维护<br>
现在版本 com.locationtech.jts 由eclipse开源基金会托管<br>
## 使用说明

## 代码包结构

核心模块:  

* `jts-core` - 核心类库:提供geometry model, operations, algorithms, and spatial data structures  
* `jts-io-common` - I/O classes for open spatial formats  

The following modules depend on proprietary libraries, and are not built by default:  

* `jts-io-ora` - Oracle reader and writer  
* `jts-io-sde` - SDE reader and writer  

The following modules are applications and data for testing and working with JTS  

* `jts-tests` - The JTS XML test suite and the Test Runner application  
* `jts-app` -The TestBuilder GUI, for working with JTS geometry interactively
