transformation_tesselate
Convert polygons into triangle meshes for geospatial analysis. This tool processes GeoJSON polygon data and outputs a collection of triangular features using Turf.js tesselation methods.
Instructions
将多边形分割为三角形。
该函数使用 Turf.js 库的 tesselate 方法，将给定的多边形分割为三角形集合。
Args: polygon: GeoJSON Polygon 特征 - 类型: str (JSON 字符串格式的 GeoJSON) - 格式: 必须符合 GeoJSON Polygon 规范 - 坐标系: WGS84 (经度在前，纬度在后) - 示例: '{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[11, 0], [22, 4], [31, 0], [31, 11], [21, 15], [11, 11], [11, 0]]]}}'
Returns: str: JSON 字符串格式的三角形集合 GeoJSON FeatureCollection - 类型: GeoJSON FeatureCollection with Polygon features - 格式: {"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [...]}}]} - 示例: '{"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[11, 0], [22, 4], [31, 0], [11, 0]]]}}, ...]}'
Raises: Exception: 当 JavaScript 执行失败、超时或输入数据格式错误时抛出异常
Example: >>> import asyncio >>> polygon = '{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[11, 0], [22, 4], [31, 0], [31, 11], [21, 15], [11, 11], [11, 0]]]}}' >>> result = asyncio.run(tesselate(polygon)) >>> print(result) '{"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[11, 0], [22, 4], [31, 0], [11, 0]]]}}, ...]}'
Notes: - 输入参数 polygon 必须是有效的 JSON 字符串 - 坐标顺序为 [经度, 纬度] (WGS84 坐标系) - 返回的三角形集合覆盖原始多边形的整个区域 - 依赖于 Turf.js 库和 Node.js 环境
