[GRASS-user] problem creating point layer from CSV file

[Tim Michelsen]

Hello,
I tried to create a point vector from a table with coordinates:

db.in.ogr dsn=points_in.csv output=points key=myid
v.in.db --overwrite table=points x=UTM_E y=UTM_N key=myid output=points_vect
=> ERROR: x/y/z column must be integer or double

Why do I get this error?
How to I change the table column format for an imported ascii (CSV) 
table in order to match integer or double?

Thanks for your help.

Kind regards,
Timmie
