<title>SQL-MM Functions</title>
|
||||
|
||||
<para>This is a listing of the SQL-MM defined functions that PostGIS
|
||||
currently supports. The implementations of these functions follow the
|
||||
ArcSDE implementation, and thus deviate somewhat from the spec. These
|
||||
deviations will be noted.</para>
|
||||
|
||||
<para>As of version 1.2.0, these functions have been implemented by
|
||||
wrapping existing PostGIS functions. As a result, full support for
|
||||
curved geometries may not be in place for many functions.</para>
|
||||
|
||||
<note>
|
||||
<para>SQL-MM defines the default SRID of all geometry constructors as
|
||||
0. PostGIS uses a default SRID of -1.</para>
