SQL function for GEOSEqualsExact
|Reported by:||Mike Taves||Owned by:||pramsey|
|Priority:||medium||Milestone:||PostGIS Fund Me|
This enhancement request is to add an SQL function to access GEOSEqualsExact from the GEOS C API to find geometries that are equal, up to a specified tolerance. A suggested prototype would be:
boolean ST_EqualsExact(geometry A, geometry B, integer tolerance DEFAULT 6);
Although a name ST_AlmostEquals might better describe the desired operation, since it is designed to provide equality for inexact geometries.
External to GEOS, it is used in Shapely as object.almost_equals(other[, decimal=6])
