[Qgis-user] Creating Geometries for tabular data

[Matthias Kuhn]

I use the process on a postgis DB, but Shapefiles are also capable of
having tabular data without geometries attached.
However I do not know how you would create such a file (easily) from an
existing geometry-less layer.

Maybe something like this:
http://gis.stackexchange.com/questions/327/how-can-i-convert-an-excel-file-with-x-y-columns-to-a-shapefile

Or try with adding a dummy geometry column in a csv so it loads as
points and then save as shapefile.

Best,
Matthias
