Create a text file with just the header. Use the cat command to join this file and the xyz file.<br>$ cat HeaderFile.csv file1.csv > file1.csv<br>You can repeat this on all files in a shell script.<br><br>Otherwise add the following line in the gdal2xyz.py script at line 144 [1].<br>
<br><span style="font-family: courier new,monospace;">dst_fh</span><span style="font-family: courier new,monospace;" class="o">.</span><span style="font-family: courier new,monospace;">write</span><span style="font-family: courier new,monospace;" class="p">(</span><span style="font-family: courier new,monospace;"> '</span><span style="font-family: courier new,monospace;">Longitude,</span><span style="font-family: courier new,monospace;">Latitude,Name' )</span><br>
<br>You will also have to create a separate vrt file for each csv file. The SrcDataSource element value changes for each file.<br><br>[1]: <a href="http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/python/scripts/gdal2xyz.py?rev=21127#L145">http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/python/scripts/gdal2xyz.py?rev=21127#L145</a><br>

Chaitanya,<br><br>if I understand properly, I need to add one line to each of processed files.<br>How I can do it quickly? Is there any option in gdal2xyz.py script?<br><br>If no - what would You recommend?<br>I think about sed utility, but it's general difficult in use.<br>
<br>When I am thinking about Python I see only one possibility - load each file to variable and then assign to another first line plus variable and at last - save it.<br><br>==============<br>Best Regards,<br>Mateusz<br>

Mateusz,<br><br>gdal2xyz.py creates space delimited fields. Consider running it with the -csv option to delimit it with comma.<br>Now you can almost use it as a csv format vector file. You just need to add a header row and define a small VRT file as described in OGR's CSV driver page[1].<br>
Run ogrinfo and ogr2ogr on the .vrt file to check the file.<br><br>[1]: <a href="http://www.gdal.org/ogr/drv_csv.html" target="_blank">http://www.gdal.org/ogr/drv_csv.html</a><br><br><div class="gmail_quote"><div><div></div>

My idea (I don't know any plugin or any functionality in GDAL/OGR which allow to do it easier) is to export raster using gdal2xyz.py into coordinates-value format and then save it as vector (GML or shapefile).
