Prepare geometry（准备几何图形）¶
Supported in: Batch, Streaming
Prepares a geometry for downstream use, for example indexing to the ontology, by converting a geometry string into valid GeoJSON. Polygons will be closed and deduplicated. Geometries which cross the anti-meridian (as indicated by width > 180 degrees) will be split into multiple features on each side of the anti-meridian. By default, this operation will return the converted geometry, or null if the string cannot be converted. Alternatively, in the "show errors" output mode, this operation will instead output a struct containing either the successfully parsed output or a descriptive error message.
Expression categories: Geospatial
Declared arguments¶
- Geometry string: Geometry string to be parsed and converted to GeoJSON.
Expression\ - optional Output mode: Choose to output as a simple output where the output is the resulting geometry and errors are returned as null, or output a struct with two fields: an "ok" field with the resulting geometry if it can be converted; otherwise, an "error" field containing a descriptive error message.

Output type: Geometry | Struct\

中文翻译¶
准备几何图形¶
支持：批处理（Batch）、流处理（Streaming）
通过将几何图形字符串转换为有效的 GeoJSON，为下游使用（例如索引到本体）准备几何图形。多边形将被闭合并去重。跨越反子午线（以宽度 > 180 度表示）的几何图形将被分割为反子午线两侧的多个要素。默认情况下，此操作将返回转换后的几何图形，如果字符串无法转换则返回 null。或者，在"显示错误"输出模式下，此操作将输出一个结构体，其中包含成功解析的输出或描述性错误消息。
表达式类别： 地理空间（Geospatial）
声明的参数¶
- 几何图形字符串（Geometry string）： 要解析并转换为 GeoJSON 的几何图形字符串。
表达式\ - 可选 输出模式（Output mode）： 选择输出为简单输出（输出结果为几何图形，错误返回 null），或输出包含两个字段的结构体：一个"ok"字段包含可转换的结果几何图形；否则，一个"error"字段包含描述性错误消息。
