坐标系说明

BD09(百度坐标系)

百度地图使用的坐标系统,在GCJ02基础上再次加密。

GCJ02(火星坐标系)

中国国测局制定的地理信息系统坐标系统,是对WGS84进行加密后的坐标系。

WGS84

GPS原始坐标系统,目前广泛使用的GPS全球卫星定位系统使用的坐标系统。

Web Mercator

网页地图使用的投影坐标系统,将球面坐标转换为平面坐标。用于距离和面积计算时可以获得更准确的结果。

注意事项

  1. 坐标转换精度与原始数据质量有关
  2. 中国大陆以外的坐标,WGS84与GCJ02坐标系转换将直接返回原始坐标
  3. Web Mercator坐标通常以米为单位
  4. 距离和面积计算使用Web Mercator投影后的平面计算方法,适用于中小尺度的计算
  5. 对于跨越大洲的超长距离或超大面积,建议使用球面计算方法
  6. 多边形面积计算不需要手动闭合,程序会自动处理闭合

FAQ

What is the GeoCalculator MCP server?
GeoCalculator is a Model Context Protocol (MCP) server profile on explainx.ai. MCP lets AI hosts (e.g. Claude Desktop, Cursor) call tools and resources through a standard interface; this page summarizes categories, install hints, and community ratings.
How do MCP servers relate to agent skills?
Skills are reusable instruction packages (often SKILL.md); MCP servers expose live capabilities. Teams frequently combine both—skills for workflows, MCP for APIs and data. See explainx.ai/skills and explainx.ai/mcp-servers for parallel directories.
How are reviews shown for GeoCalculator?
This profile displays 10 aggregated ratings (sample rows for discoverability plus signed-in user reviews). Average score is about 4.5 out of 5—verify behavior in your own environment before production use.
