mcp_geo_calculate_area

Calculate polygon area using coordinates in WGS84, GCJ02, or BD09 systems. Supports units like square meters, square kilometers, or hectares. Automatically handles polygon closure and performs calculations via Web Mercator projection. Ideal for small to medium-scale spatial analysis.

Instructions

计算多边形面积。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投影进行平面面积计算。多边形无需手动闭合。适用于中小尺度的面积计算。
