Solimyr,<br><br>For shapefiles just copying and renaming the .prj file might be enough. Extents can be computed and stored using the ogr2ogr utility.<br><br>If copying the .prj file didn't work, you can use the -s_srs option in the ogr2ogr utility. You can get the SRS WKT from the ogrinfo output.<br>
<br>Of course, you can do this programatically using OGRDataSource::CopyLayer() method. The spatial reference has to be set to each layer in a datasource. There is no GeoTransform. You can force calculation of extent using OGRLayer::GetExtent() method.<br>

Hi guys,<br>
I have two shapefile with same features but one miss the extent and the<br>
projection. What I want to do is copy the extent and the projection from the<br>
first and set to the second. I did something similar with two images using<br>
these step:<br>
<br>
inputimg = gdal.Open(str(fileName), GA_ReadOnly)<br>
gdalformat= inputimg.GetDriver().ShortName<br>
geoinput = inputimg.GetGeoTransform()<br>
projinput= inputimg.GetProjection()<br>
..<br>
outimg = gdal.Open(str(result), GA_Update)<br>
outimg.SetProjection(projinput)<br>
outimg.SetGeoTransform(geoinput)<br>
<br>
<br>
Do you know if there is something similar to this but for shapefile? Do you<br>
have any suggests?<br>
thx<br>
