[mapserver-users] Tinyows exchange coords when POST request.

[Rahkonen Jukka (MML)]

Hi,

This is not true "the result will be ALWAYS in reversed format."

The bug seems to be specific for EPSG:3003. See what your own server does with EPSG:3067:

http://www502.regione.toscana.it/wfsvector/com.rt.wfs.RTmap/wfs?service=WFS&version=1.1.0&request=GetFeature&typename=sita:idstradertline&maxfeatures=1&srsName=EPSG:3067


http://www502.regione.toscana.it/wfsvector/com.rt.wfs.RTmap/wfs?service=WFS&version=1.1.0&request=GetFeature&typename=sita:idstradertline&maxfeatures=1&srsName=urn:ogc:def:crs:EPSG::3067

No flip which is correct. The place to correct the bug is to find out where TinyOWS is analyzing if coordinates must be flipped or not and consider how to get EPSG:3003 into the list of no-flip systems.

After this I stopthe testing because need to do another urgetn work.
Now I need to restart the question of what wfs use for our service.

This a very complicated question because the clients will return the values listesd in the capabilities.
And if the capabilities report always a reversed format, the result will be ALWAYS in reversed format.
:(

I notice infact that when call for a getcapabilities from a tinyows.

http://www502.regione.toscana.it/wfsvector/com.rt.wfs.RTmap/wfs?service=WFS&version=1.1.0&request=GetCapabilities

It return always the srs of the layers always using the urn notation:

<DefaultSRS>urn:ogc:def:crs:EPSG::3003</DefaultSRS><OtherSRS>urn:ogc:def:crs:EPSG::25832</OtherSRS><OtherSRS>urn:ogc:def:crs:EPSG::4326</OtherSRS><OtherSRS>urn:ogc:def:crs:EPSG::3857</OtherSRS><OtherSRS>urn:ogc:def:crs:EPSG::6707</OtherSRS>

And this mean that the client will send a request using the same notation.
But these mean also , as reported me from Olivier, thattinyows will return always the axis reversed.

This is a sample of a call with a correct axis order:
http://www502.regione.toscana.it/wfsvector/com.rt.wfs.RTmap/wfs?service=WFS&version=1.1.0&request=GetFeature&typename=sita:idstradertline&maxfeatures=1&srsName=EPSG:3003

http://www502.regione.toscana.it/wfsvector/com.rt.wfs.RTmap/wfs?service=WFS&version=1.1.0&request=GetFeature&typename=sita:idstradertline&maxfeatures=1&srsName=urn:ogc:def:crs:EPSG::3003

So I need to understand of the reversing axis in tinyows is a bug patchable or a standardized response.
And also I need to understand if is right that the getcapabilites will return the srs list always in URN format .

Any hint on this ?

Thx.

A.
