Oracele Spatial 11g - 2D-3D Geometry Extrusion

Question

Hi,
I am trying to extrude some 2d data that is lat long format to 3d using the sdo_util.extrude function. The SQL workflow is as follows:
*1. Create 2d data table, insert data and index*
--table for 2d data
CREATE TABLE "EGOVIS"."DUBLIN_F_TEST"
(     "FID" NUMBER(38,0),
     "ID" NUMBER(38,0),
     "ZV" FLOAT(126),
     "X" FLOAT(126),
     "Y" FLOAT(126),
     "GEOM" "MDSYS"."SDO_GEOMETRY"
--insert data
Insert into DUBLIN_F_PROJECT (FID,ID,ZV,X,Y,GEOM)
values
47,
1,
97,
-6.27175835549,
53.3369421474,
MDSYS.SDO_GEOMETRY(
2003
,8307
,NULL
,SDO_ELEM_INFO_ARRAY(
1,
1003,
1),
SDO_ORDINATE_ARRAY(
-6.271393982,53.337082684,
-6.271432654,53.337085933,
-6.271441366,53.337051319,
-6.271337218,53.337041470,
-6.271303925,53.337037787,
-6.271287361,53.337035957,
-6.271278835,53.337071497,
-6.271335773,53.337077243,
-6.271393982,53.33708268)));
--insert metadata
INSERT INTO USER_SDO_GEOM_METADATA VALUES
'DUBLIN_F_PROJECT',
'GEOM',
MDSYS.SDO_DIM_INFO_ARRAY
MDSYS.SDO_DIM_ELEMENT('Longitude', -180, 180, 0.5),
MDSYS.SDO_DIM_ELEMENT('Latitude',-90, 90, 0.5)
8307
--create spatial index
CREATE INDEX "EGOVIS"."DUBLIN_F_PROJECT_SINDX" ON "EGOVIS"."DUBLIN_F_PROJECT" ("GEOM")
INDEXTYPE IS "MDSYS"."SPATIAL_INDEX" ;
*2. create 3d data table and Extrude data into DUBLIN_E_PROJECT table*
--create table
CREATE TABLE "EGOVIS"."DUBLIN_E_TEST"
(     "FID" NUMBER(38,0),
     "ID" NUMBER(38,0),
     "ZV" FLOAT(126),
     "X" FLOAT(126),
     "Y" FLOAT(126),
     "GEOM" "MDSYS"."SDO_GEOMETRY"
--extrude 2d data from DUBLIN_F_PROJECT to DUBLIN_E_PROJECT
INSERT
INTO
DUBLIN_E_PROJECT
SELECT
FID
,ID
,ZV
,X
,Y
,SDO_UTIL.EXTRUDE(
GEOM
,SDO_NUMBER_ARRAY(0)
,SDO_NUMBER_ARRAY(20)
,'TRUE'
,0.05)
from DUBLIN_F_PROJECT
when i try to extrude the data i get the following error:
*An error was encountered performing the requested operation:
ORA-29532: Java call terminated by uncaught exception:
java.lang.Exception: 54550
ORA-06512: at "MDSYS.SDO_UTIL",line 222
29532. 0000 - "Java call terminated by uncaught Java exception: %s"
*Cause: A Java exception or error was signaled and could not be resolved by the Java code.
*Action: Modify Java code, if this behavior is not intended.
Error at Line:1*
I have tried to drop the index and perform the extrusion but that does not help. Does any one have advice on how to solve this problem?
Thanks for suggestions,
Keith.

Answer 1

Thanks for that siva,
I have successfully extruded the data into 3d data. i now need to index the data. My steps are as follows:
*1. update srid of data to 3d srid*
update dublin_sample_test a set a.geom.sdo_srid=4327;
*2. insert metadata for said data with height value*
INSERT INTO USER_SDO_GEOM_METADATA VALUES
'DUBLIN_sample_test3',
'GEOM',
MDSYS.SDO_DIM_ARRAY
MDSYS.SDO_DIM_ELEMENT('Longitude', -180, 180, 0.00005),
MDSYS.SDO_DIM_ELEMENT('Latitude',-90, 90, 0.00005),
MDSYS.SDO_DIM_ELEMENT('Height',0, 300, 0.00005)
4327 --wgs84 3d
*3. create 3d index on table*
CREATE INDEX dublin_sample_test3_SIDX
ON dublin_sample_test3 ("GEOM")
INDEXTYPE IS
MDSYS.SPATIAL_INDEX PARAMETERS ('sdo_indx_dims=3');
I have tried but at index creation stage I am getting the following error:
ERROR at line 1:
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-13236: internal error in R-tree processing: [specified index dimensionality
should be 2 for geodetic indexes]
ORA-06512: at "MDSYS.SDO_INDEX_METHOD_10I", line 10
29855. 00000 - "error occurred in the execution of ODCINDEXCREATE routine"
*Cause:   Failed to successfully execute the ODCIIndexCreate routine.
*Action: Check to see if the routine has been coded correctly.
Error at Line: 3 Co;umn: 13
Can you please advise me on the process of selecting a 3d srid for wgs84(lat/long) data and tell me if I am doing anything incorrect here.
Thanks,
keith.
