coordtransform

提供百度坐标系(BD09)、火星坐标系(国测局坐标系、GCJ02)、WGS84坐标系的相互转换，基于 Rust 语言，无特殊依赖。 Provides mutual conversion between Baidu Coordinate System (BD09), Mars Coordinate System (GCJ02), and WGS84 Coordinate System, implemented in Rust with no special dependencies.

坐标系说明

Coordinate System Description

• WGS84坐标系：即地球坐标系，国际上通用的坐标系
• WGS84 Coordinate System: The Earth coordinate system, commonly used internationally.
• GCJ02坐标系：即火星坐标系，WGS84坐标系经加密后的坐标系。Google Maps，高德在用
• GCJ02 Coordinate System: Also known as the Mars coordinate system, an encrypted version of the WGS84 coordinate system. Used by Google Maps and Amap.
• BD09坐标系：即百度坐标系，GCJ02坐标系经加密后的坐标系
• BD09 Coordinate System: Also known as the Baidu coordinate system, an encrypted version of the GCJ02 coordinate system.
• EPSG:3857坐标系：即Web墨卡托投影坐标系，广泛用于Web地图服务
• EPSG:3857 Coordinate System: Also known as Web Mercator projection, widely used in web mapping services.

Usage Example 使用示例
