Using MapViewer to view a georaster: blue display

Question

Hi,
I uploaded a tiff file into a georaster table. I followed all the steps to georeference the raster, generate the spatial extent, create the pyramids, etc.
Then I executed the steps to make my raster ready for viewing:
- Insert a row into the USER_SDO_GEOM_METADATA
- Create a spatial index on the spatial extent of the GeoRaster table
Once I use 'MapViewer' all I see is a blue screen. I'm using the 'georaster.jsp' that come up with 'MapViewer' installation to view my raster. Any ideas of what could be wrong ?
Any help is appreciated
Jeff

Answer 1

Joao,
The log file under "c:\mypath\MapViewer\mvqs10_1_2_0_2\oc4j\j2ee\home\applications\mapviewer\web\WEB-INF\log\mapviewer.log' is indedd empty.
1)
To georeference the tiff, I used a .tfw file, set the SRID and generate the spatial extent:
DECLARE
geo SDO_GEORASTER;
BEGIN
SELECT GEORASTER INTO geo FROM Raster1 WHERE ID=1 FOR UPDATE;
SDO_GEOR.IMPORTFROM(geo,'blocksize=(512,512)','TIFF','file','/export/home/oracle/large.TIFF',
'WORLDFILE','file','/export/home/oracle/large.tfw');
UPDATE Raster1 SET GEORASTER = geo WHERE ID=1;
COMMIT;
END;
DECLARE
geo sdo_georaster;
BEGIN
SELECT georaster INTO geo FROM Raster1 WHERE id=1 FOR UPDATE;
sdo_geor.setModelSRID(geo, 32611);
UPDATE Raster1 SET georaster = geo WHERE id=1;
END;
UPDATE Raster1 c
SET c.georaster.spatialExtent = sdo_geor.generateSpatialExtent(georaster)
WHERE c.id = 1;
COMMIT;
2) Here is the result of the metadata query:
