7.71 SDO_GEOR.getLayerDimension
Format
SDO_GEOR.getLayerDimension( georaster IN SDO_GEORASTER ) RETURN SDO_STRING_ARRAY;
Description
Returns the dimension that is mapped as the logical layer dimension of a GeoRaster object.
Usage Notes
The layer dimension refers to the physical entity associated with the logical
term layer. For the current release, the only supported layer dimension is
BAND
: that is, the logical concept layer is associated
with the physical term band, as shown in Figure 1-5 in Bands_ Layers_ and Metadata. In this case,
layers will be mapped to the BAND
dimension, so that the first
layer is band 0, the second layer is band 1, and so on.
Examples
The following example returns the layer dimension of each GeoRaster object (GEORASTER column) in the GEORASTER_TABLE table, whose definition is presented after Example 1-1 in Storage Parameters. (The output is reformatted for readability.)
SELECT georid, sdo_geor.getLayerDimension(georaster) FROM georaster_table; GEORID SDO_GEOR.GETLAYERDIMENSION(GEORASTER) ---------- ------------------------------------------------------------------ 2 SDO_STRING_ARRAY('BAND') 4 SDO_STRING_ARRAY('BAND')
