+Databend 内置两套互补的地理空间能力：PostGIS 风格的几何（Geometry）函数，用于构建与分析形状；以及 H3 实用工具，用于全球六边形索引。下表按任务对函数进行分组，方便您快速定位所需工具，布局方式与 Snowflake 文档类似。
+
+## 几何构造函数
+
+| 函数 | 描述 | 示例 |
+|----------|-------------|---------|
+| [ST_MAKEGEOMPOINT](st-makegeompoint.md) / [ST_GEOM_POINT](st-geom-point.md) | 构造 Point（点）几何体 | `ST_MAKEGEOMPOINT(-122.35, 37.55)` → `POINT(-122.35 37.55)` |
+| [ST_MAKELINE](st-makeline.md) / [ST_MAKE_LINE](st-make-line.md) | 由若干 Point 创建 LineString（线串） | `ST_MAKELINE(ST_MAKEGEOMPOINT(-122.35, 37.55), ST_MAKEGEOMPOINT(-122.40, 37.60))` → `LINESTRING(-122.35 37.55, -122.40 37.60)` |
+| [ST_MAKEPOLYGON](st-makepolygon.md) | 由闭合 LineString 创建 Polygon（多边形） | `ST_MAKEPOLYGON(ST_MAKELINE(...))` → `POLYGON(...)` |
+| [ST_POLYGON](st-polygon.md) | 由坐标环创建 Polygon | `ST_POLYGON(...)` → `POLYGON(...)` |
+
+## 几何转换
+
+| 函数 | 描述 | 示例 |
+|----------|-------------|---------|
+| [ST_GEOMETRYFROMTEXT](st-geometryfromtext.md) / [ST_GEOMFROMTEXT](st-geomfromtext.md) | 将 WKT 转换为几何体 | `ST_GEOMETRYFROMTEXT('POINT(-122.35 37.55)')` → `POINT(-122.35 37.55)` |
+| [ST_GEOMETRYFROMWKB](st-geometryfromwkb.md) / [ST_GEOMFROMWKB](st-geomfromwkb.md) | 将 WKB 转换为几何体 | `ST_GEOMETRYFROMWKB(...)` → `POINT(...)` |
+| [ST_GEOMETRYFROMEWKT](st-geometryfromewkt.md) / [ST_GEOMFROMEWKT](st-geomfromewkt.md) | 将 EWKT 转换为几何体 | `ST_GEOMETRYFROMEWKT('SRID=4326;POINT(-122.35 37.55)')` → `POINT(-122.35 37.55)` |
+| [ST_GEOMETRYFROMEWKB](st-geometryfromewkb.md) / [ST_GEOMFROMEWKB](st-geomfromewkb.md) | 将 EWKB 转换为几何体 | `ST_GEOMETRYFROMEWKB(...)` → `POINT(...)` |
+| [ST_GEOMFROMGEOHASH](st-geomfromgeohash.md) | 将 GeoHash 转换为几何体 | `ST_GEOMFROMGEOHASH('9q8yyk8')` → `POLYGON(...)` |
+| [ST_GEOMPOINTFROMGEOHASH](st-geompointfromgeohash.md) | 将 GeoHash 转换为 Point 几何体 | `ST_GEOMPOINTFROMGEOHASH('9q8yyk8')` → `POINT(...)` |
+| [TO_GEOMETRY](to-geometry.md) | 解析多种格式为几何体 | `TO_GEOMETRY('POINT(-122.35 37.55)')` → `POINT(-122.35 37.55)` |
+
+## 几何输出
+
+| 函数 | 描述 | 示例 |
+|----------|-------------|---------|
+| [ST_ASTEXT](st-astext.md) | 将几何体转换为 WKT | `ST_ASTEXT(ST_MAKEGEOMPOINT(-122.35, 37.55))` → `'POINT(-122.35 37.55)'` |
+| [ST_ASWKT](st-aswkt.md) | 将几何体转换为 WKT | `ST_ASWKT(ST_MAKEGEOMPOINT(-122.35, 37.55))` → `'POINT(-122.35 37.55)'` |
