转换公式 Conversion Formula
GCJ02坐标系与WGS84坐标系之间的转换采用简化的布尔莎模型，公式如下： The conversion between GCJ02 and WGS84 coordinate systems uses a simplified Bursa-Wolf model, with the following formula:
// GCJ02 → WGS84 WGS84_Lat = GCJ02_Lat - 0.0068197 WGS84_Lon = GCJ02_Lon - 0.0067498 // WGS84 → GCJ02 GCJ02_Lat = WGS84_Lat + 0.0068197 GCJ02_Lon = WGS84_Lon + 0.0067498 // GCJ02 → WGS84 WGS84_Lat = GCJ02_Lat - 0.0068197 WGS84_Lon = GCJ02_Lon - 0.0067498 // WGS84 → GCJ02 GCJ02_Lat = WGS84_Lat + 0.0068197 GCJ02_Lon = WGS84_Lon + 0.0067498
注：此公式为简化模型，适用于大多数中国地区。对于高精度要求的应用，建议使用专业的坐标转换软件。 Note: This is a simplified model suitable for most regions in China. For high-precision applications, professional coordinate conversion software is recommended.

转换公式 Conversion Formula
GPS坐标格式转换公式如下： The GPS coordinate format conversion formulas are as follows:
// 时分秒 (DMS) → 小数点 (DD) DD = 度 + 分/60 + 秒/3600 如果是南纬或西经，则结果为负数 // 小数点 (DD) → 时分秒 (DMS) 度 = 整数部分(DD的绝对值) 分 = 整数部分((DD的绝对值 - 度) × 60) 秒 = ((DD的绝对值 - 度) × 60 - 分) × 60 方向：北纬为N，南纬为S，东经为E，西经为W // Degrees Minutes Seconds (DMS) → Decimal Degrees (DD) DD = degrees + minutes/60 + seconds/3600 If it's south latitude or west longitude, the result is negative // Decimal Degrees (DD) → Degrees Minutes Seconds (DMS) degrees = integer part of (absolute value of DD) minutes = integer part of ((absolute value of DD - degrees) × 60) seconds = ((absolute value of DD - degrees) × 60 - minutes) × 60 Direction: North latitude is N, south latitude is S, east longitude is E, west longitude is W
