7.105 SDO_GEOR.isOrthoRectified
Format
SDO_GEOR.isOrthoRectified( georaster IN SDO_GEORASTER ) RETURN VARCHAR2;
Description
Returns the string TRUE
if the GeoRaster object is identified as orthorectified, or FALSE
if the GeoRaster object is not identified as orthorectified.
Usage Notes
This function checks the GeoRaster metadata for the object to see if it is specified as orthorectified. It does not check if the object is actually orthorectified. Users are responsible for validating the GeoRaster object and ensuring that orthorectification is performed.
To specify that a GeoRaster object is orthorectified, use the SDO_GEOR.setOrthoRectified procedure.
Examples
The following example checks if the GeoRaster objects (GEORASTER column) in the GEORASTER_TABLE table are specified as spatially referenced, rectified, and orthorectified. (The GEORASTER_TABLE table definition is presented after Example 1-1 in Storage Parameters.)
SELECT georid, substr(sdo_geor.isSpatialReferenced(georaster),1,20) isSpatialReferenced, substr(sdo_geor.isRectified(georaster),1,20) isRectified, substr(sdo_geor.isOrthoRectified(georaster),1,20) isOrthoRectified FROM georaster_table; GEORID ISSPATIALREFERENCED ISRECTIFIED ISORTHORECTIFIED ---------- -------------------- -------------------- -------------------- 2 TRUE TRUE TRUE 4 TRUE TRUE FALSE
