In Quantum GIS, I already imported an excel or dbf table. Now I need to tell Quantum GIS which columns are Latitude and Longitude. How do I do that?
I know there is Add Delimited Text Layer which allows that, but it seems Unreasonable to me to convert XLS or DBF file to text file before importing! There must be some direct way of telling QGIS that these parameters of the imported attribute table are actualy x y data.
