It looks like it may have worked, but you should be careful to ensure that if you do not have a .prj file (which defines the projection information for the shape file) that you tell ogr2ogr what projection system the file is actually in. In your case, it looks like you did not need to tell ogr2ogr what the projection system was (it guess for you) , but you cannot always be sure with shape files what the projection system actually is without a bit of prior knowledge of the nature of the file, or having its metadata.
>From the ogr2ogr manual.. This option controls the output projection. -t_srs srs_def:Reproject/transform to this SRS on output This option controls the input spatial reference system, which ogr2ogr will attempt to read from the .prj file if it is present. If not, you may get an error like the one you say above. -s_srs srs_def:Override source SRS Regards, Jason On Tue, Feb 26, 2013 at 5:19 PM, Paulo Grácio <[email protected]> wrote: > I just get the following warning message > > Warning 1: Layer name 'MOZ_adm1-polygons-ms1' adjusted to > 'MOZ_adm1_polygons_ms1' for XML validity.
