[Gvsig_english] Oracle Spatial with LRS

[Juan Lucas Dominguez Rubio]

Hello,
 
currently, gvSIG's Oracle Spatial driver does not support LRS geometries. I think with some minor changes it would be possible to at least read (browse) those geometries, but you still would not be able to interact with the M value from gvSIG. To achieve this, a further development would be needed.
 
Regards,

Hi all,
My routes (carreteras) table has Linear Referencing System because I want to set the measure. 
So it has x,y and a m but the index is in 2D because Oracle recomends that since m isn't z or height.

In gvSIG I can show points, polygons but with lines gives me the error:

Error while getting valid geometry fields:
no_index_on_declared_geo_fields: SCHEMA.LINE_TABLE

I think it is because of LRS, but that is essential for my project.

gvSIG doesn't work with LRS?

I created the index with this:

create index IS_LN_03 on BDR_LINE (
   GEOMETRY_LN
) INDEXTYPE IS MDSYS.SPATIAL_INDEX
PARAMETERS('TABLESPACE=BDRLNX WORK_TABLESPACE=BDRTMP LAYER_GTYPE=MULTILINE sdo_indx_dims=2')
