GIS 坐标转换 Skill
快速转换点、线、面数据的坐标系：WGS84（经纬度）↔ Web Mercator（EPSG:3857）
快速开始
转换 GeoJSON 到墨卡托
python3 ~/.openclaw/workspace/skills/gis-coord-transform/scripts/transform_coords.py input.geojson -t mercator -o output.geojson --pretty
转换墨卡托回经纬度
python3 ~/.openclaw/workspace/skills/gis-coord-transform/scripts/transform_coords.py input.geojson -t wgs84 -o output.geojson --pretty
支持的几何类型
| 类型 | 说明 |
|---|---|
| Point | 点 |
| LineString | 线 |
| Polygon | 面 |
| MultiPoint | 多点 |
| MultiLineString | 多线 |
| MultiPolygon | 多面 |
| Feature | GeoJSON 要素 |
| FeatureCollection | 要素集合 |
命令行参数
| 参数 | 说明 |
|---|---|
input |
输入 GeoJSON 文件路径 |
-o, --output |
输出文件路径（默认输出到 stdout） |
-t, --to |
目标坐标系：mercator 或 wgs84 |
--pretty |
美化输出 JSON |
使用示例
示例 1：转换单个点
// input.geojson
{
"type": "Point",
"coordinates": [116.4074, 39.9042]
}
python3 scripts/transform_coords.py input.geojson -t mercator
输出（墨卡托坐标）：
{
"type": "Point",
"coordinates": [12958396.7, 4865942.3]
}
示例 2：转换 FeatureCollection
python3 scripts/transform_coords.py cities.geojson -t mercator -o cities_mercator.geojson --pretty
示例 3：批量转换
for file in *.geojson; do
python3 scripts/transform_coords.py "$file" -t mercator -o "${file%.geojson}_mercator.geojson"
done
依赖安装
pip3 install pyproj
坐标系说明
| 坐标系 | EPSG 代码 | 用途 |
|---|---|---|
| WGS84 | EPSG:4326 | GPS、经纬度、地理坐标 |
| Web Mercator | EPSG:3857 | Web 地图（Google Maps、OpenStreetMap、Mapbox 等） |
常见问题
为什么转换后坐标数字变大了？
Web Mercator 使用米为单位，而 WGS84 使用度。墨卡托坐标通常在百万级别。
转换精度如何？
使用 pyproj 库，精度非常高，适合专业 GIS 应用。
支持其他坐标系吗？
当前版本仅支持 WGS84 ↔ Web Mercator。如需其他坐标系，可扩展 pyproj.Transformer。
扩展建议
需要添加其他坐标系转换时，修改脚本中的 Transformer 定义：
# 例如：WGS84 → CGCS2000 (EPSG:4490)
transformer = Transformer.from_crs("EPSG:4326", "EPSG:4490", always_xy=True)

Usage Guidance
This skill appears to do exactly what it claims: convert GeoJSON geometries between WGS84 and Web Mercator. Before installing, note that it depends on the pyproj Python package (pip3 install pyproj). The script works on files you point it at and will write output where you specify — so make sure you run it on files you trust and choose an output path you control. If you prefer the skill not to run autonomously, disable autonomous invocation in the agent settings. There are no signs of network calls, hidden endpoints, or credential requests.
Capability Analysis
Type: OpenClaw Skill
Name: gisransformcoords
Version: 1.0.0
The skill is a legitimate GIS utility designed to transform GeoJSON coordinates between WGS84 and Web Mercator. The primary script, `scripts/transform_coords.py`, uses the standard `pyproj` library for calculations and performs safe file I/O and JSON processing without any evidence of malicious execution, data exfiltration, or obfuscation. The documentation in `SKILL.md` provides clear, helpful instructions for the AI agent and lacks any prompt-injection attempts or suspicious commands.
Capability Assessment
Purpose & Capability
Name, description, SKILL.md, and the included Python script all describe and implement GeoJSON coordinate conversion between WGS84 and Web Mercator. Required tools (pyproj) are appropriate for the task; nothing unrelated (cloud credentials, other services) is requested.
Instruction Scope
SKILL.md instructs running the provided script on local GeoJSON files and shows example command-lines (including a path under ~/.openclaw/workspace/skills/... which matches normal skill placement). The runtime instructions do not ask the agent to read arbitrary unrelated files, environment variables, or contact external endpoints. Minor note: examples reference an absolute workspace path; this is informational and not a security concern.
Install Mechanism
No install spec is provided (instruction-only with an included script). Dependencies are limited to pyproj, and SKILL.md correctly instructs installing it via pip. No downloads from untrusted URLs or archive extraction are present.
Credentials
The skill requires no environment variables, credentials, or config paths. The script reads only the user-specified input file and writes the specified output — this is proportional to its purpose.
Persistence & Privilege
always is false and the skill does not request persistent/system-wide changes. It can be invoked autonomously (platform default) but that is normal and not combined with broad privileges or credential access.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install gisransformcoords - After installation, invoke the skill by name or use
/gisransformcoords - Provide required inputs per the skill's parameter spec and get structured output
