Name

bb_makepoint — produce a PostGIS geometry point in the WGS 1984 UTM Zone 37South coordinate system from X and Y coordinates

Synopsis

`geometry bb_makepoint (`	`X`,
	`Y)`;


                  double precision
                  X

;


                  double precision
                  Y

;

Input

X

The X coordinate of the point in the WGS 1984 UTM Zone 37South coordinate system. A double precision number, or any other data type that can be interpreted as a number and converted to double precision.

Y

The Y coordinate of the point in the WGS 1984 UTM Zone 37South coordinate system. A double precision number, or any other data type that can be interpreted as a number and converted to double precision.

Description

Return a PostGIS geometry point in the WGS 1984 UTM Zone 37South coordinate system, the geolocation coordinate system used within Babase. Such points can be used in geospatial analysis.

This is a convenience function that is shorthand for the PostGIS expression: ST_SetSRID(ST_MakePoint(x, y), 32737). However, unlike ST_MakePoint(), bb_makepoint requires that either both x and y be NULL or neither be NULL.
