This section shows you how to take any linestring or polygon geometry object and decompose it even further than
ST_ExplodeGeometry; not just the extraction of individual elements and subelements, but right down to individual vectors. A vector is a directed two vertex linestring.
(X1,Y2) ---> (X2,Y2) E.g. SDO_GEOMETRY(2002,NULL,NULL, SDO_ELEM_INFO_ARRAY(1,2,1), SDO_ORDINATE_ARRAY (1,1,2,1))
The only level lower than this is the individual vertex level!
Vectorization of an
SDO_GEOMETRY object requires access to all the vertices of that object. The
SDO_UTIL.GetVertices function can be used to return the vertices of an
SDO_GEOMETRY object in a form that is easy and natural to work with. This function returns the ...
