A stupid question, just in case. You say that AsBinary returns a valid
geometry, but does it have a collection with points? I mean, could it be an
empty collection?
Also, are you sure the encode function is not corrupted? If AsBinary returns
something hexadecimal, the encode function should have no problem, no matter
if the geometry is valid or not. Have you tried to run the encode function
with the result of the AsBinary? And with something simpler?

Unfortunately starting with a given PostGIS version some output functions (in addition to input functions) added simple checks for validity. ST_AsBinary must be one of them. Canonical input and output functions were fixed in latest 1.4, 1.5 and trunk, to allow for dump/reloads in presence of invalid data, see http://trac.osgeo.org/postgis/ticket/411 Whether ST_AsBinary should also be fixed is debatable. I suggest you file a ticket and continue the discussion there. --strk; () Free GIS Flash consultant/developer /\ http://strk.keybit.net/services.html ___ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
[postgis-users] Mapserver with postgis, sql query error.
Hi,
I'm a newby with this.
I have a shape file that I upload to postGis Database, with the windows
program postgis and dbf loader.
Then I create a test with MS4W environment.
I setup a LOG in the map file.
And the error y following:
*code*

The table is populated, everything looks fine, but I can't see any map.
Then I enter the SQl Query in the SQL Window of pgAdmin III, and start to
rewrite this sql query:
select encode(AsBinary(force_collection(force_2d(the_geom)),'NDR'),'hex')

** Error **
ERROR: geometry requires more points

If I extract function AsBinary, there is no error:

Here is my question:
1) How to check if the data is correct ?
2) do I have lo load data with shp2pgsql command line utility?
3) any idea ?
Best Regards.

Re: [postgis-users] Mapserver with postgis, sql query error.
Hey Nicholas,
I'm a newbie, but just to say that I've used the 'Spit' tool within
QGIS to load shapefiles into PostGIS - mght be worth a look. You can
also then load the table into QGIS once it is in the system to see if
it has stored it correctly?

Re: [postgis-users] Mapserver with postgis, sql query error.
Hi Sandro, my second question, is because the firs time I load data using the GUI interface of tha utility. But I just loaded via command line, and I guet the same error ... In the table I got 67811 records, the error means that ALL of them have a problem ? or at leastone of them? In that case, how can I know wich one is? How is it posible that if I can see the map using the shape file, but I can't using the postgis database ? Thanks and looking fordward to a solution ...

Yes, sorry, sometimes I ask before try ! In the table was 134 records wrong ...

Another question is whether or not ST_AsBinary should complain rather than letting an invalid geometry slip out (which may be what you mean by the shape is ok). --strk; () Free GIS Flash consultant/developer /\ http://strk.keybit.net/services.html ___ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
