Mixed SRID geometries

jason.king@q-free.com
All,

We're noticing an issue attempting to access a GeoRSS feed from Geoserver
pointed at a Postgres database.   It seems to be intermittent and seems that
the it happens when we start Geoserver and there is no data in the table
that the layer is in.  If we start Geoserver with data in the table it
appears to work fine.  We have several other layers that do not display this
behavior when Geoserver is started and there's no data in the table.  They
all appear to be configured in a similar and correct fashion.

We were able to get SQL logging and determined exactly which query is
happening when we receive the error, and the query that's happening when we
do not.  The difference of course is the SRID.  When Geoserver is started
with no data in the table the query uses '0' as the SRID even after data is
entered into the table.  When it's started with data the query uses '4326'.

We have been unable to track down what would cause this behavior and ANY
help or direction at this point would be greatly appreciated!  Here are the
where clauses of both queries:

Failing:
WHERE
  "start_point"
&& ST_GeomFromText(
  'POLYGON ((-83.65630587023 36.53687411899, -83.65630587023 39.44093367457,
-75.34445594167 39.44093367457, -75.34445594167 36.53687411899,
-83.65630587023 36.53687411899))', 0)
AND ST_Intersects(
  "start_point",
  ST_GeomFromText('POLYGON ((-83.65630587023 36.53687411899, -83.65630587023
39.44093367457, -75.34445594167 39.44093367457, -75.34445594167
36.53687411899, -83.65630587023 36.53687411899))', 0))

Succeeding:
WHERE
  "start_point"
&& ST_GeomFromText(
  'POLYGON ((-83.65630587023 36.53687411899, -83.65630587023 39.44093367457,
-75.34445594167 39.44093367457, -75.34445594167 36.53687411899,
-83.65630587023 36.53687411899))', 4326)
AND ST_Intersects(
  "start_point",
  ST_GeomFromText('POLYGON ((-83.65630587023 36.53687411899, -83.65630587023
39.44093367457, -75.34445594167 39.44093367457, -75.34445594167
36.53687411899, -83.65630587023 36.53687411899))', 4326))

Please let me know what else I can provide.

Thanks in advance!

Re: Mixed SRID geometries

geowolf
Hi,
normally GeoServer figures out the srid of the data from the geometry_columns view/table,
without needing to look at the data. Checking the first record found is the last resort, and works only
if there is data of course.

So, could it be that the user you specified in the datastore connection parameters is not granted
access to the geometry_columns view?

Cheers
Andrea
