[gdal-dev] RE: Conversion of MapInfo to GML using ogr2ogr - lat/long format issue

[mysticraja]

Thanks Guys..

The following command helped me achieve it.

ogr2ogr -dsco FORMAT=GML3 -t_srs "EPSG:4283" -f "GML" <output.xml> <input.MID>

You can remove GML_CONSIDER_EPSG_AS_URN which has only an influence when reading
GML, not writing GML.

By default, the GML driver writes GML2.1 geometries, that traditionnaly didn't
honour EPSG axis ordering rules.

If you add -dsco FORMAT=GML3 , then you will have GML3 geometries, and by
default the coordinates for a SRS like EPSG:4283 will be written in lat/long
order (because the default value of the dataset creation option GML3_LONGSRS is
YES).

For more details on those 2 creations options, you can refer to
http://gdal.org/ogr/drv_gml.html

Best regards,

Even
