[gdal-dev] ogr2ogr interlis 1 driver arguments

2013-05-28 Thread Mario Jurcevic
Hi, with gdal 1.9.2 when passing to ogr2ogr the layer names to import ( interlis 1 driver ) some layers could not be found. Instead when importing the whole file everything is OK. The ili file contains 109 layers. Is there some limitations on the arguments length? Thanks. Regards, Mario

Hello everybody, I have tired to read gml file from National Land Suvey of Finnish without a success. Does anybody have any idea what's the problem? The gml has a quite complex schema. Is this a problem for ogr? I have tried to download all the schema files to the same folder with the same name

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

A friend, a relative newcomer to GIS, is having problems loading some of the TIFs created with Mapinfo into QGIS. Each TIF has a TAB file and in some cases the TAB file is interpreted correctly and in other cases the TAB file is (apparently) not recognised. I think this might be a problem with
