[gdal-dev] GMLAS does not resolve schema from WFS data

[Rahkonen Jukka (MML)]

Thanks,

I added CPl_CURL_VERBOSE but I do not quite understand what it tries to tell me. GDAL seems to reach the deegree WFS server but then "* no chunk, no close, no size. Assume close to signal end"
* Couldn't find host inspire-wfs.maanmittauslaitos.fi in the _netrc file; using defaults

I don't reproduce this issue on Ubuntu 16.04. You can try adding --config CPL_CURL_VERBOSE YES to get more low level details about what goes wrong



But I get other errors :



$ ogrinfo gmlas:inspire-cp.gml

ERROR 1: /vsicurl_streaming/https://inspire-wfs.maanmittauslaitos.fi/inspire-wfs/cp?SERVICE=WFS&VERSION=2.0.0&REQUEST=DescribeFeatureType&OUTPUTFORMAT=application%2Fgml%2Bxml%3B+version%3D3.2&NAMESPACE=xmlns%28http%3A%2F%2Finspire.ec.europa.eu%2Fschemas%2Fau%2F4.0%29:11:73 namespace 'http://inspire.ec.europa.eu/schemas/base/3.3' is referenced without import declaration

ERROR 1: /vsicurl_streaming/https://inspire-wfs.maanmittauslaitos.fi/inspire-wfs/cp?SERVICE=WFS&VERSION=2.0.0&REQUEST=DescribeFeatureType&OUTPUTFORMAT=application%2Fgml%2Bxml%3B+version%3D3.2&NAMESPACE=xmlns%28http%3A%2F%2Finspire.ec.europa.eu%2Fschemas%2Fau%2F4.0%29:114:73 namespace 'http://inspire.ec.europa.eu/schemas/base/3.3' is referenced without import declaration

[...]



The schema at https://inspire-wfs.maanmittauslaitos.fi/inspire-wfs/cp?SERVICE=WFS&VERSION=2.0.0&REQUEST=DescribeFeatureType&OUTPUTFORMAT=application%2Fgml%2Bxml%3B+version%3D3.2&NAMESPACE=xmlns(http%3A%2F%2Finspire.ec.europa.eu%2Fschemas%2Fau%2F4.0) indeed references namespaces without importing them (except GML). It indeed looks invalid to me.
