[Geoserver-users] WFS data probleme

Hi!

I want to know if it’s possible to make a wfs’s request on a shapefile in postgis with geoserver and to know if data must be prepared to the wfs.

Thanks!

Hi,

It is for sure possible to use shapefiles as input for Geoserver, and it is possible also to import the shapefile to PostGIS first and use the resulting database table as input for Geoserver. Both ways you can use the data through WFS. Creating WFS feature type happens almost automatically it you just follow the documentation and create DataStore first, then FeatureType.

Thanks for your answer,

But before the import in geoserver does shapefiles need to be particularly formated because I can access to my data in wms but not in wfs.
I access to “states” shapefile in wfs.

There should be no difference. How are you exactly trying to access your data in wfs? Do you see the feature type in WFS GetCapabilities document? If yes, what happens when you throw getFeature request?

Hi,

I believe that everything is OK but Geoserver just does not find any data from the BBOX of the request.
I guess that problem is close to this point:
&SRS=EPSG=27572&
BBOX=-6.091001143333474,41.347434706580835,
10.812650506643369,51.089559943887004

SRS=EPSG=27572 is obviously wrong, EPSG:27572 should be better. Or just leave the SRS and BBOX out and ask for the whole feature type first, perhaps with maxFeatures parameter,

Thanks it’s ok

That work if I don’t specify the BBOX parameter.

But I use Openlayers to make a map with wfs layers and when it make requests he specify the BBOX.

this is my function:
var wfs = new OpenLayers.Layer.WFS(
“States WFS”,“http://localhost:8080/geoserver/wfs”,
{typename: ‘topp:france’},
{
layers: ‘france’,
featureNS: ‘http://www.openplans.org/topp’,
style:fStyle,
extractAttributes: true

},
{‘reproject’: true}
);

I don’t show data on my map. Firebug show me the request and BBOX is specify.

Hi,

Search from spatialreference.org
http://spatialreference.org/ref/epsg/27572/
returns among other things:

  • WGS84 Bounds: -5.2000, 42.2500, 8.2300, 51.1000
  • Projected Bounds: -22841.3905, 1712212.6192, 1087335.9605, 2703971.1254

You should use the projected units (meters) in the request instead of lon/lat bounding box.

Sorry I’m french and I don’t understand what you said :s

It’s the unit of my BBOX is wrong?

I must project my data in wgs84 to use wfs?

Openlayers generate the BBOX automatically, I don’t know if it’s possible to change this parameter.

Aihe: [Geoserver-users] WFS data probleme

Hi!

I want to know if it’s possible to make a wfs’s request on a shapefile in postgis with geoserver and to know if data must be prepared to the wfs.

Thanks!

Hi,

WFS SRS and bbox must be using the same projection and units. If output it asked to be in EPSG:4326 then bbox must use degrees in wgs84. If output is asked to be the French projection EPSG:27572 then bbox must be in meters, because it is the unit for 27572. In your case using SRS=EPSG:4326 may help. Unfortunately I do not know anything about Openlayers.

Hi,

Search from spatialreference.org
http://spatialreference.org/ref/epsg/27572/
returns among other things:
*WGS84 Bounds*: -5.2000, 42.2500, 8.2300, 51.1000
*Projected Bounds*: -22841.3905, 1712212.6192, 1087335.9605, 2703971.1254

You should use the projected units (meters) in the request instead of
lon/lat bounding box.

Thanks it's ok

That work if I don't specify the BBOX parameter.

But I use Openlayers to make a map with wfs layers and when it make
requests he specify the BBOX.

this is my function:
var wfs = new OpenLayers.Layer.WFS(
            "States WFS","http://localhost:8080/geoserver/wfs&quot;,
            {typename: 'topp:france'},
            {
                layers: 'france',
                featureNS: 'http://www.openplans.org/topp’,
                style:fStyle,
                extractAttributes: true

            },
            {'reproject': true}
        );

I don't show data on my map. Firebug show me the request and BBOX is
specify.

Hi,

I believe that everything is OK but Geoserver just does not find any data
from the BBOX of the request.
I guess that problem is close to this point:
*&SRS=EPSG=27572&*
*BBOX=-6.091001143333474,41.347434706580835,*
*10.812650506643369,51.089559943887004*
*SRS=EPSG=27572 *is obviously wrong, EPSG:27572 should be better. Or
just leave the SRS and BBOX out and ask for the whole feature type first,
perhaps with maxFeatures parameter,

There should be no difference. How are you exactly trying to access
your data in wfs? Do you see the feature type in WFS GetCapabilities
document? If yes, what happens when you throw getFeature request?

  Thanks for your answer,

But before the import in geoserver does shapefiles need to be
particularly formated because I can access to my data in wms but not in
wfs.
I access to "states" shapefile in wfs.

Jim.

2009/4/3 Rahkonen Jukka <Jukka.Rahkonen@anonymised.com>

Hi,

It is for sure possible to use shapefiles as input for Geoserver, and it
is possible also to import the shapefile to PostGIS first and use the
resulting database table as input for Geoserver. Both ways you can use the
data through WFS. Creating WFS feature type happens almost automatically it
you just follow the documentation and create DataStore first, then
FeatureType.

Hi,

WFS version 1.0.0 does not officially support reprojecting the data. However, Geoserver gives this possibiolity as a vendor option. It is documented here:
http://geoserver.org/display/GEOSDOC/WFS+vendor+parameters

It looks like the format to be used in request is like &srsName="EPSG:4326"
The way you have tried in your requests is wrong, Geoserver does not recognise it at all but just skips it. Therefore the first request works, because with it the bbox is in the native and advertised projection of your data.

You can configure Geoserver to send the data out by default in EPSG:4326 if you want, withour reprojecting the original data. Then the EPSG:4326 bounding box should work without srsname parameter.

When I make the datastore geoserver translate 47680.0 to -5.498977524054812 when I push "generate" for BBOX

I don't understand what is wrong because is geoserver who make translate, he make mistake?

Nope, your request is invalid in a couple of ways.
First, the bbox that GeoServer shows you in the configuration
page is always the lat/lon one, no matter what your native
SRS is, because OGC pretends we publish at least a lat/lon
bbox for each layer (thus that bbox _must_ be calculated).

The first error is that the two requests are using a parameter
that does not exist in WFS, &EPSG. WFS 1.0 has officially
no reprojection abilities, but GeoServer supports the
same parameter as WFS 1.1 as a vendor option.
The second error is that your second request, in case you
really need to use WGS84, does not specify it as the
SRS in the bbox.

Two valid requests are:
http://localhost:8080/geoserver/wfs?typename=dep_france_dom&VERSION=1.0.0&REQUEST=GetFeature&BBOX=47680.0,1620431.0,1197822.0,2677441.0
(data in the native srs, bbox in the native srs)

http://localhost:8080/geoserver/wfs?typename=dep_france_dom&VERSION=1.0.0&REQUEST=GetFeature&srsName=EPSG:4326&BBOX=-5.498977524054812,41.347434706580835,10.812650506643369,51.089144192296196,EPSG:4326
(asking the data to be reprojected in 4326, notice how I specified the spatial reference system for the bbox too).

Hope this helps
Cheers

Thanks for answers!

I have understand the different requests, this is a wfs request generate by openlayers:

http://localhost:8080/geoserver/wfs?typename=topp%3Adep_france_dom&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&SRS=EPSG%3A900913&BBOX=-3124370.6613745,4043340.933843,3724387.0717505002,7956916.781343

they don’t work.

They work if the EPSG:4326 is specify in the BBOX

http://localhost:8080/geoserver/wfs?typename=topp%3Adep_france_dom&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&SRS=EPSG%3A900913&BBOX=-3124370.6613745,4043340.933843,3724387.0717505002,7956916.781343,EPSG:4326

I don’t know if it’s possible to specify in openlayers to put this information but may be it’s possible to configure geoserver to work without this information?

Thanks for your help!
