WKT

从各种Geo 数据类型生成 WKT (Well Known Text) 几何对象。支持的 WKT 对象包括：

• POINT
• POLYGON
• MULTIPOLYGON
• LINESTRING
• MULTILINESTRING

语法

WKT(geo_data)

参数

geo_data 可以是以下 Geo 数据类型 之一，或其底层基本类型：

• Point
• Ring
• Polygon
• MultiPolygon
• LineString
• MultiLineString

返回值

• 对于 Point，返回 WKT 几何对象 POINT。
• 对于 Polygon，返回 WKT 几何对象 POLYGON
• 对于 MultiPolygon，返回 WKT 几何对象 MULTIPOLYGON。
• 对于 LineString，返回 WKT 几何对象 LINESTRING。
• 对于 MultiLineString，返回 WKT 几何对象 MULTILINESTRING。
