[mapserver-users] wfs 1.1.0 via mapserver and ogr

[Jachym Cepicky]

Hi,

Hi,

I try to load some data to MapServer (and  display them as WMS) from
WFS 1.1.0 server (also MapServer-based).

>From various reasons, I defined the WFS layer as OGR layer type, with
connection set to WFS definition file:

  LAYER
    CONNECTION "wfs.wfs"
    CONNECTIONTYPE OGR
    DATA "line"
    #EXTENT 12.735342 48.152419 17.141855 51.38089
    METADATA
      "ows_abstract"	"My abstract"
      "wfs_typename"	"line"
      "wfs_version"	"1.1.0"
      "wms_title"	"Line"
    END # METADATA
    NAME "line"
    PROJECTION
      "+init=epsg:4326"
    END # PROJECTION
    STATUS ON
    TEMPLATE "foo"
    TILEITEM "location"
    TYPE LINE
    UNITS METERS
    CLASS
      STYLE
        ANGLE 0
        COLOR 238 153 0
        OFFSET 0 0
        OUTLINECOLOR 134 81 0
        SIZE 5
        WIDTH 5
      END # STYLE
    END # CLASS
  END # LAYER


(wfs.wfs should be attached to this e-mail).

When I try to display the data (using shp2img or standard WMS
request), nothing is displayed, because of MapServer->OGR asks the WFS
server with following request:


http://localhost/cgi-bin/ows?SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&TYPENAME=line&FILTER=<Filter
 xmlns:gml="http://www.opengis.net/gml"><BBOX><PropertyName>msGeometry</PropertyName><gml:Box><gml:coordinates>48.7275012197312094,12.9295317871890720
51.1769623652315175,18.1965700336475784</gml:coordinates></gml:Box></BBOX></Filter>

This is WRONG because of the axes are inverted, the filter *should* look like

12.9295317871890720,48.7275012197312094 18.1965700336475784,51.1769623652315175

Then it works.

My question is, where can/should I influence this behaviour? I tried
several options in PROJECTION section of the MapFile (+axis=neu, ...)
but nothing made the OGR driver to change the axes order.

So it seems, that MapServer is creating the WFS 1.0.0 style filters with
Easting-Northing also when the connection is defined as WFS 1.1.0 and
 gml Box is used in the filter, but Box does not exist in GML3 and
Envelope should be used instead. (according to
http://lists.osgeo.org/pipermail/gdal-dev/2011-June/029029.html)


With WFS 1.0.0 it works perfectly (axes are in EAST-NORTH order).

What to do, so that mapserver reades WFS 1.1.0 via OGR properly?

Thanks

Jachym
