St_linefromtext
WebST_LineFromText (varchar) Returns a value in the geometry data type line. Example: SELECT ST_Line ( 'linestring (1 1, 2 2, 3 3)') ST_LineString (array (point)) Returns a LineString geometry type formed from an array of point geometry types. If there are fewer than two non-empty points in the specified array, an empty LineString is returned. WebKunlunBase改名Klustron通知 Klustron 的概要和优势 一、系统架构 二、核心能力

WebST_LineFromText. ST_LineFromText takes a string column and returns a linestring column. The string column must contain the well-known text (WKT) representation of linestring geometries. You can optionally specify a spatial reference for the result linestring column. The sr parameter value must be a valid SRID or WKT string. Function. Syntax.

WebThe INSERT statements insert an ST_MultiLineString record that is not closed and another that is. The query lists the results of the ST_IsClosed function. The first row returns 0 or f because the multilinestring is not closed. The second row returns 1 or t because the multilinestring stored in the ln1 column is closed.

WebThe ST_Geometry function is the most flexible of the spatial type constructor functions because it can create any spatial type from various geometry representations. For example, ST_LineFromText can create a line from WKT line or ST_WKTToSql can construct any type, but only from WKT format. WebDefinition ST_LineFromText takes a well-known text representation of type ST_LineString and a spatial reference ID and returns an ST_LineString. Syntax sde.st_linefromtext (wkt clob, srid integer) Return type ST_LineString Example The linestring_test table is created with a single ln1 ST_LineString column.

ST_MakePoint is perhaps in terms of speed the fastest way of creating a PostGIS geometry and on tests I have done, can be as much as 5 to 10 times faster.
