GPS Convert
===========

[](#gps-convert)

- WGS-84：是国际标准，GPS坐标（Google Earth使用、或者GPS模块）
- GCJ-02：中国坐标偏移标准，Google Map、高德、腾讯使用
- BD-09：百度坐标偏移标准，Baidu Map使用

使用说明
----

[](#使用说明)

```
use GPS\Convert;
```

**WGS-84 to GCJ-02:**

```
Convert.gcj_encrypt();
```

**GCJ-02 to WGS-84 粗略:**

```
Convert.gcj_decrypt();
```

**GCJ-02 to WGS-84 精确(二分极限法):**

```
Convert.gcj_decrypt_exact();
```

**GCJ-02 to BD-09:**

```
Convert.bd_encrypt();
```

**BD-09 to GCJ-02:**

```
Convert.bd_decrypt();
```

**求距离:**

```
Convert.distance();
```

\*\*注意：\*\*本算法 gcj算法、bd算法都非常精确，已经测试通过。（BD转换的结果和百度提供的接口精确到小数点后4位），请放心使用。
