David,
Okay. I'm not familiar with that example, but it seems to read in
georss rather than GML.
Perhaps you can hand form your coordinates into georss suitable for
loading into that example by:
1) Converting your geometries to EPSG:4326 srid
2) Concatenating the geometries together with the georss xml
3) Giving the file a header with a scripting language or javascript
1 and 2 can be accomplished like so:
Drop table if exists test;
Select ST_GeomFromEWKT('SRID=24877;POINT(723852.689845968
9683464.33250772)') as geometry, '1995-12-12T05:00:00Z'::text as time
into test;
Select '<item><pubDate>' || time || '</pubDate><geo:lat>' ||
ST_Y(ST_Transform(geometry,4326))
|| '</geo:lat><geo:long>' || ST_X(ST_Transform(geometry,4326)) || '</
geo:long></item>' from test;
which gives:
<item><pubDate>1995-12-12T05:00:00Z</
pubDate><geo:lat>-78.9862916594766</
geo:lat><geo:long>-2.86196482025465</geo:long></item>
and looks somewhat similar to what is used in the point track example:
http://openlayers.org/dev/examples/xml/track1.xml
Does that help?

Hi Dane...
Yeah... I'm using OpenLayers....
I'neet to use the Track Point Marker example where the xml file it't
indispensable...
But for example>
the coords of my city in my xml file
713620.5057, 9673754.1986
and the coords of my city in the example map
-79.86664 -20.54546
Because I'm using this function
x(the_geom), y(the_geom)
If I use asewkb(the_geom)>
"\001\001\000\000 -a\000\000\240}3a\031\027&A;\347\243\012AxbA"
And with asewkt(the_geom)>
"SRID=24877;POINT(723852.689845968 9683464.33250772)"

Hi David,
I'm not sure about that error, but if you are exporting from postgis
to be able to be read into an OpenLayers map you can also use the
WKT format, as well as GeoJson and KML.
So, you are not web to GML.
Cheers,
Dane

Hi List,
I need to convert my geometry to GPS position.... I'm trying with
asgml(geometry)
But I have this error.. ERROR: Only GML 2 and GML 3 are supported
And this is my version of postgis..
"POSTGIS="1.3.3" GEOS="3.0.0-CAPI-1.4.1" PROJ="Rel. 4.6.0, 21 Dec
2007" USE_STATS DBPROC="0.3.0" RELPROC="1.3.3" (needs proc upgrade)"
I need this, because I need to generate a xml file with the GPS
format of my points...
Thanks Advanced...!!
