Hi!
I have postgresql table with point data type column "mypointloc". When i
have tried to create vectors (points) object in GRASS 6.2.2
v.in.db driver=pg database="localhost,dbname=aeronet" table=mytable
x=mypointloc[0] y=mypointloc[1] key=myid output=mynewtable
I have got message " WARNING: pg driver: column 'mypointloc', type 600
is not supported"!
Result table "mynewtable" have not x and y columns.
afaik you have to specify two new collumns of types (float or double),
for x and y coordinates.
grass does not support "point" column type used in potgresql
Does you mean - it is better do not use postgresql tables with point
type? It is strange for me!
How I have create vectors(points) objects from postgresql table?
Is it possible to create new vectors(points) without creation new
attribute table?
yes, v.in.ascii should do the job
OK! I think it is lucky thought. I will try to create ascii file from
postgresql table and then I will use v.in.ascii.
Thank you!
Basil
