Hi,
I am having problems with scaling the cell value according to the scaling function specified in the metadata. The values in the cells are retrieved as they are stored when I am using sdo_geor.getcellvalue and they are not scaled according to the scaling function specified. How to get the scaled values? The following is my metadata:
