[fdo-users] coordinate system bug?

I think with help I have discovered that the descrepincies in my sde.spatial_references table are due to problems while loading the data and getting it registered correctly with sde. I have clipped previous data and added a short piece of output showing the auth_name.

Yes I have verified that the sdelayers have the correct coordinate definition. However it was just explained to me by esri that the srid in sde is a moving target. each time sde finds any variation (not sure why it htinks there is any variation) it creates a new srid value (random) and assigns the description see below.  From esri support >>>3. As we discussed, the 3rd party software maybe should read the auth_srid to get the Oracle spatial coordinate system definition. But in general cases, if a layer is not from Oracle spatial, there may not be the auth_id value.ESRI's ID (comparable to Oracle's SRID)http://arcweb.esri.com/arcwebonline/services/pcs_alpha.htmNAD_1983_StatePlane_Oklahoma_North_FIPS_3501  32124    Oracle Database 10g Release 10.2.0.3.0 - ProductionSQL> select distinct SRID from sde.spatial_references;      SRID----------         1         2         3         4         5         6         7         8         9        10        11      SRID----------        12        13        14        15        16        17        18        19        20        21        22
