<div dir="ltr">Hi Ari,<div><br></div><div style>I think that shouldn't be neccessary.</div><div style>The gml file points to the xsd schema file (<a href="http://xml.nls.fi/XML/Schema/Maastotietojarjestelma/MTK/201202/Maastotiedot.xsd">http://xml.nls.fi/XML/Schema/Maastotietojarjestelma/MTK/201202/Maastotiedot.xsd</a>).</div>
<div style>In this schema those tags are defined to be "aliases" for these known gml tags by using the substitutionGroup. So actually that <Maastotiedot> is a <gml:FeatureCollection>. Is this supported by OGR?</div>

There are at least these issues with the file:<br>
<br>
- Piste should be gml:Point<br>
- Murtoviiva should be gml:LineString<br>
- Alue should be gml:Polygon<br>
- all features should be wrapped into gml:featureMember elements<br>
- everything should be in gml:FeatureCollection<br>
- complex geometries should be wrapped into gml:GeometryCollection
elements<br>
<br>
With these changes and limitations I can open (a small piece) of
the file with ogrinfo. All are probably changeable by XSLT. Of
course my knowledge about GML and it's parsing in GDAL is limited,
so take this with a grain of salt.<br>
<br>
Cheers,<br>
