[Qgis-user] QGis/Grass - slow Vector export

[Thomas Wahlmüller]

Hi

I am exporting vector features with v.out.ogr. I tried with QGIS via
Plugin and with GRASS. My Dataset is a point-feature with more than 1
million points with height attribute.

Exporting to shape is realy slow - 1 day ~ 30% exported

I also tried to export with v.out.ascii. In this case export also slow
with output of heigt-attribute. Output was fast without attribute
information. So it seems to me - accessing attribute data in grass slows
down the process...


By the way: I needed to convert a Raster to Point, because I had
Artefacts (stripes of lower height-value) after reprojection with GDAL.
Are there any other solutions?
