Changes in Oracle Database Release 21c

The following are changes in Oracle Spatial GeoRaster Developer's Guide for Oracle Database Release 21c.

New Formats for SDO_GEOR_RA.stack Procedure

For the SDO_GEOR_RA.stack procedure, several new formats are added with SYS_REFCURSOR input and simplified band number specification using the bandNumber parameter. Previously, only SDO_GEORASTER_ARRAY input was available for this procedure.

New mask Parameter Formats for SDO_GEOR.generateStatisticsXxx Functions

Each SDO_GEOR.generateStatisticsXxx function has a new format that includes the mask parameter, allowing you to use a bitmap mask to specify the pixels or areas for the statistics calculation. For information, see the following reference topics: SDO_GEOR.generateStatistics, SDO_GEOR.generateStatisticsMax, SDO_GEOR.generateStatisticsMean, SDO_GEOR.generateStatisticsMedian, SDO_GEOR.generateStatisticsMin, SDO_GEOR.generateStatisticsMode, SDO_GEOR.generateStatisticsSTD, and SDO_GEOR.generateStatisticsSum.

New Function in SDO_GEOR Package

SDO_GEOR.generateStatisticsSum is added to the SDO_GEOR package. This function computes statistical data associated with one or more layers, and returns the sum value.
