;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.
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.
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.
