I want to use Podtgre DB for storing my georeferentced points data. With these points i should be able to do some interpolation with the values conteined as attribute into the pg table. Into the table i want to store some attributes (some numerics and text attributes) and the point's geografical coordinates. After i want to view and use that data just like a grass vector map (i dont want any data transfert, grass should read the data and show it -and use for interpolation-). I know it is possible, but is necessary to use the postgis extension? or can i use a normal postgre table for storing my data?
Thanks
