mcp_geo_calculate_distance
Calculate the distance of a polyline across multiple coordinate systems. Input coordinates are converted to WGS84, then projected for planar distance calculation. Supports units in meters or kilometers.
Instructions
计算折线的距离。支持多种坐标系统输入，内部会先转换为WGS84坐标，再通过Web Mercator投影进行平面距离计算。适用于中小尺度的距离计算。
