gdal2xyz.py creates space delimited fields. Consider running it with the
-csv option to delimit it with comma.
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
Run ogrinfo and ogr2ogr on the .vrt file to check the file.
