Selecting a GeoRaster

Once a connection has been established, the sub-datasets window will show the names of all the tables that contains GeoRaster columns in that database in the format of a GDAL subdataset name. <P> Click on one of the listed subdatasets and then click on Select to choose the table name. Now another list of subdatasets will show with the names of GeoRaster columns on that table. This is usually a short list, since most users will not have more than one or two GeoRaster columns on the same table. <P> Click on one of the listed subdatasets and then click on Select to choose one of the the table/column combination. The dialog will now show all the rows that contains GeoRaster objects. Note that the subdataset list will now show the Raster Data Table and Raster Id's pairs. <P> At anytime the Selection entry can be edited in order to go directly to a known GeoRaster or to go back to the beginning and select another table name. <P>

<P> The Selection data entry can also be used to enter a Where clause at the end of the identification string, e.g., ``geor:scott/tiger@orcl,gdal_import,raster,geoid=.http://www.gdal.org/frmt_georaster.html< for more information.
