Hi Ari, I think that shouldn't be neccessary. The gml file points to the xsd schema file ( http://xml.nls.fi/XML/Schema/Maastotietojarjestelma/MTK/201202/Maastotiedot.xsd ). 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?
I'm not an xml/gml expert either so it's hard to find the problem. -Lauri On Tue, May 28, 2013 at 5:11 PM, Ari Jolma <[email protected]> wrote: > Lauri, > > There are at least these issues with the file: > > - Piste should be gml:Point > - Murtoviiva should be gml:LineString > - Alue should be gml:Polygon > - all features should be wrapped into gml:featureMember elements > - everything should be in gml:FeatureCollection > - complex geometries should be wrapped into gml:GeometryCollection elements > > With these changes and limitations I can open (a small piece) of the file > with ogrinfo.
