sdelayer based on SDO_GEOMETRY view not shown in ArcGIS: spatial index does not exist

CarelBodegraven — Wed, 31 Oct 2012 14:32:17 GMT

We need to use the outlines of a multipolygon layer SDO_GEOMETRY in an Oracle database as a multiline layer in SDE. We would like to maintain a dynamic relationship with the original polygons-layer.

Therefor in Oracle we made a database view, changing the the geometrytype to line using "sdo_util.polygontoline(shape)", which resulted in correct values in the Shape-column: MDSYS.SDO_GEOMETRY(2006... and MDSYS.SDO_GEOMETRY(2002...

After that we applied "insert into user_sdo_geom_metadata values...." to the view

And we registered the view as a layer in SDE: sdelayer -o register...

In ArcCatalog the table is now correctly presented in ArcCatalog as line-layer. The lines, however, are not visible in ArcMap. Just when you select a feature in the feature table it does show exactly like a selected feature in any other (valid) layer.

When using a tool on the layer, I get the error: Spatial index does not exist [ORA-13226.......

We tried several things like sdelayer -o normal_io

Does anyone have a suggestion to get the layer working properly (other then creating a materialized view)

Thanks,
Carel

Hi Carel,

What was your exact "sdelayer -o register" command syntax?

Have you tried using "sdelayer -o alter -E CALC" command to recalculate the layer envelop after you registered the SDO layer with SDE?

Thanks,
Ben L.

Hi Ben,

Thanks for your reaction!

I used: sdelayer -o register -i 5151 -u wshd -p password -s isp -l KERINGEN_SVW_ZONERINGEN_LN,geometrie -e nl+ -t SDO_GEOMETRY -k SDO_GEOMETRY -C GZN_ID,USER -P HIGH -x 0,0,1000,0.001 -G 28992

I just tried sdelayer -o alter -E CALC -i 5151 -u wshd -p password -s isp -l KERINGEN_SVW_ZONERINGEN_LN,geometrie

The result was "Successfully Modified the Layer"

Layer Configuration ..: SDO_GEOMETRY

However: the layer still does not draw in ArcCatalog

Do the geometries contain Z values (elevations)? The coordref has a Z origin and scale,
but the entity flags don't support elevations ("nl+" vs. "nl+3")

The geometry does not contain Z-values:
MDSYS.SDO_GEOMETRY(2002,28992,NULL,MDSYS.SDO_ELEM_INFO_ARRAY(1,2,1),MDSYS.SDO_ORDINATE_ARRAY(51455.605,426561.375,51447.652,426558.813,51427.699,426553.625,51413.66,426551.031,51405.637,426548.5,51396.461,426548 etc.

However, neither does the original polygon layer (gw_gzn) from which the view was derived, and that layer was also registered with:
Z Offset..............: -1000.000000
Z Units ..............: 10000.000000

I think I forgot to mention the -z -1000,10000 in my earlier statement, sorry about that.

To get this to work, I think you have to create a function-based index on the output of the SDO_UTIL.POLYGONTOLINE function.

What tripped me up was that you have to fully qualify the function name when you inset the row into the sdo_geom_metadata view. If you don't, you can't create the index.

good luck

Thanks a lot Travis! this does the trick: a dynamic line-layer view on a sdo_geometry polygon-layer-table!
