Hi Zhang,
There is no problem.
This is the ewkb format used by postgis in order to storing geo data.
Use the astext() function if you want to see you data in human
readable format (wkt)
select astext(the_geom) from pt_gsqy_point;
it should be good! :)

Hi
I have searched the forum but am still confused about the geometry_columns
table. Importing and deleting PostGIS layers doesn't seem to have an effect
on the geometry_columns table, very strange as this is a GIS catalog to the
spatial database.
I require this table (geometry_columns) to be up
Those tables are only modified by PostGIS using the following functions
or by direct user intervention (yes you can modify it directly and I do
when I'm creating views since there is currently no way to make the
table add a view)
The postgis functions I know of that update that table are the

I have a table with foll fields( the_geom, name, latlon, )...i wanted to
make a polygon by using those points whose name like 'abc' and put it in the
map...
how to do dis?

Are each of your the_geom single point geometries?
If so I think you can do something of the form
SELECT Max(f.gid) as newgid, ST_MakePolygon(ST_MakeLine(f.the_geom)) As
newgeom, f.name
FROM (SELECT gid, the_geom FROM foll ORDER BY name, gid) As f
WHERE f.name = 'abc'
GROUP BY f.name

You can also do this with ogr2ogr - http://fwtools.maptools.org/
If you have a personal geo database format and you are on windows, then you can
just specify the file path to the mdb something of the form
ogr2ogr -append -f "PostgreSQL" PG:"host=pghost user=pgloginname
dbname=pgdbname password
Thanks everybody for the heads up! Finally my installation worked out. I had problems
cause I installed everything from the sources except proj.4 (used an rpm package). After
installing proj.4 from the sources, and after adding the /usr/local/lib path to the
LD_LIBRARY_PATH env., it seems as if
exportSQL v3.2 does a really good job at this (Access VBA Macro).

If I recall correctly, it did not work out-of-the-box and I tuned it a
bit to suit my needs and to correct some things that had changed in

It looks like HostGIS offers PostGIS, along with MapServer and some
other OS GIS software.

I am using HostGIS and have been very happy with it. I think there is a
new version coming out soon.

Hello,
I am interested in the SQL-MM Part 3 geometries, especially CIRCULARSTRING.
Playing a bit around I noticed the following:
- Storing and retrieving of CIRCULARSTRING instances seems to work fine
- Spatial predicates (I tested ST_Intersects) don't seem to be supported yet
- Index based quer
Support for CIRCULARSTRING is there. Loading and retrieving of the
supported curved geometries should scale to large numbers perfectly
well, but not all the SQL-MM geometries are currently supported. In
particular, PostGIS was choking when I attempted to implement curved
polygons. Index supp
I have translated some polygon data into a PostGIS table using FME. The
translation was successful with no errors reported. All the records appear
in the PostGIS table (using the pgAdminIII application) except for about 90%
of the geometries (see image below).

Geoff,
This earlier thread may be of interest:
http://postgis.refractions.net/pipermail/postgis-users/2008-March/018814.html
It deals with limitations of pgadmin and postgis.
If the geometries really are null, are you also able to try loading the
data with ogr2ogr to see if you get the same resu
Hi Tim,
First of all I can confirm that the geometries are not null by:
a) select count(*) from where geom is null;
This returns a count of 0.
b) the FME Universal Viewer successfully displays all the geometries
successfully. Features can be graphically selected and their attributes

Hi Tim,
OK to clarify...
I have 694 records in my table, all have geometry based on the query:

When viewed in pgAdminIII only a handfull "appear" to have actual data in

I tried that but its givin the error as f.gid doesnt existin the 2nd

Ok, that's
Sorry I had a typo - try the below instead:

ST_MakePolygon(ST_MakeLine(f.the_geom)) As newgeom

Hi Tim,
We may be getting closer...
I played with 2 records as shown in the following picture...
http://www.nabble.com/file/p18231274/two_records.jpg
The first record is "good" with a geometry displayed.
The second record is "bad" with no apparent geometry, although FME says it's
there.
