<p>Hi,</p>
<p><br>
</p>
<p>Is there a way to select one or two fields from a input data source to update specific fields of an existing output data source?</p>
<p><br>
</p>
<p>Let's say I want to get the values from a prticular field of the input data source and the geometry to update a specific field and the geometry of an existing output data source.<br>
</p>
<p><br>
</p>
<p>Looking at the org2gr "-fieldmap" options it says it only work with "-append" but it doesn't examplain why. If it works it would be something like:</p>
<p><br>
</p>
<p>$ ogr2ogr -update -f format output_data_source input_data_source -nln output_layer -sql "select field1 from input_layer" -fieldmap 4</p>
<p><br>
</p>
<p>Where "4" would indicate the 3th field of the output_layer.<br>
</p>
<br>
<p>Does anybody have another solution for that?</p>
<p><br>
</p>
<p>Thanks.</p>
<p><br>
