Table 19–1 (Cont.) Spatial Utility Subprograms Subprogram Description SDO_UTIL.POLYGONTOLINE Converts all polygon-type elements in a geometry to line-type elements, and sets the SDO_GTYPE value accordingly. SDO_UTIL.PREPARE_FOR_TTS Prepares a tablespace to be transported to another database, so that spatial indexes will be preserved during the transport operation. SDO_UTIL.REMOVE_ DUPLICATE_VERTICES SDO_UTIL.REVERSE_ LINESTRING 19-2 Oracle Spatial User’s Guide and Reference Removes duplicate (redundant) vertices from a geometry. Returns a line string geometry with the vertices of the input geometry in reverse order. SDO_UTIL.SIMPLIFY Simplifies the input geometry, based on a threshold value, using the Douglas-Peucker algorithm. SDO_UTIL.TO_GMLGEOMETRY Converts a Spatial geometry object to a geography markup language (GML 2.0) fragment based on the geometry types defined in the Open GIS geometry.xsd schema document.
SDO_UTIL.APPEND Format Description Parameters Usage Notes SDO_UTIL.APPEND( geom1 IN SDO_GEOMETRY, geom2 IN SDO_GEOMETRY ) RETURN SDO_GEOMETRY; Appends one geometry to another geometry to create a new geometry. geom1 Geometry object to which geom2 is to be appended. geom2 Geometry object to append to geom1. SDO_UTIL.APPEND This function should be used only on geometries that do not have any spatial interaction (that is, on disjoint objects). If the input geometries are not disjoint, the resulting geometry might be invalid. This function does not perform a union operation or any other computational geometry operation. To perform a union operation, use the SDO_GEOM.SDO_ UNION function, which is described in Chapter 13. The APPEND function executes faster than the SDO_GEOM.SDO_UNION function. The geometry type (SDO_GTYPE value) of the resulting geometry reflects the types of the input geometries and the append operation. For example, if the input geometries are two-dimensional polygons (SDO_GTYPE = 2003), the resulting geometry is a two-dimensional multipolygon (SDO_GTYPE = 2007). An exception is raised if geom1 and geom2 are based on different coordinate systems. Spatial Utility Subprograms 19-3
