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 appears to be a straightforward local GeoJSON coordinate converter. Before installing/running: (1) ensure you install pyproj from a trusted source (pip) in a controlled environment, (2) run the script on sample/test files first to confirm output, and (3) review/scan the included script if you require stricter assurance. There are no network calls or credential requests in the code, so risks are limited to running arbitrary local Python code from an untrusted source—treat the repository origin accordingly.
Capability Analysis
Type: OpenClaw Skill
Name: gis-transform-coords
Version: 1.0.1
The skill bundle is a legitimate GIS utility for converting GeoJSON coordinates between WGS84 and Web Mercator. The Python script (scripts/transform_coords.py) uses the standard 'pyproj' library for transformations and contains no suspicious execution patterns, network calls, or data exfiltration logic.
Capability Assessment
Purpose & Capability
Name/description match the included script and SKILL.md. The requested dependencies (pyproj) and CLI behavior are appropriate for GeoJSON coordinate transforms; there are no unrelated binaries, env vars, or surprising permissions.
Instruction Scope
SKILL.md only instructs running the included script and installing pyproj. The runtime instructions operate on local GeoJSON files and do not request unrelated files, environment variables, or network endpoints.
Install Mechanism
No install spec is provided (instruction-only). The README suggests installing pyproj via pip, which is standard; there are no downloads from unknown URLs or archive extraction steps.
Credentials
The skill declares no environment variables, credentials, or config paths. The code does not access secrets or external services—only local file I/O and pyproj transforms.
Persistence & Privilege
always is false and the skill does not modify agent/system configuration or other skills. It only reads an input file and writes an output file if requested.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install gis-transform-coords - After installation, invoke the skill by name or use
/gis-transform-coords - Provide required inputs per the skill's parameter spec and get structured output
