3s-toolkit
轻量级 GNSS、大地测量和空间分析工具包，专为教学和快速原型设计。
名称说明
- 安装名（PyPI）：
3s-toolkit - 导入名（Python）：
s3_toolkit
注意：PyPI 包名以数字
3开头，但 Python 模块名不允许以数字开头， 因此导入时使用s3_toolkit（数字 3 移到末尾）。
pip install 3s-toolkit
import s3_toolkit
可选依赖（可视化）
核心库仅依赖 numpy 和 scipy。如果需要使用配套示例脚本中的绘图与 Web 可视化功能（pandas、folium、streamlit 等），请安装 viz 扩展组：
pip install 3s-toolkit[viz]
快速示例
from s3_toolkit import haversine_distance
dist = haversine_distance(30.5235, 114.3575, 39.9042, 116.4074)
print(f"武汉大学到天安门距离：{dist:.0f} 米")
功能列表
haversine_distance– 大圆距离计算latlon_to_meters– 经纬度转 Web 墨卡托米制坐标trajectory_length– 轨迹总长度elevation_stats– 高程统计speed_between_points– 点间速度nearest_neighbor_distance– 最近邻分析parse_osm_response– 地理编码响应解析
本地安装测试
在项目根目录打开终端（PowerShell），执行：
pip install -e .
然后测试导入：
python -c "import s3_toolkit as stk; print(stk.haversine_distance(30, 114, 31, 115))"
如果没有报错并输出了一个数字（如 146775.68），说明包已正常工作。
