I have been trying for a long time to connect a external table data[csv] through Excel (for exmaple) with QGis with the objective to each time i change any data in table(for example data location - coordinates [X ; Y]),this changes occur in QGis real time.

Is there any procedure to get it?.


Although the original question was aimed at raster layers, the same procedure can be applied here with simple python scripting. See https://gis.stackexchange.com/a/58885/9839

from PyQt4.QtCore import QFileSystemWatcher

def refreshLayer():
    myLayer.setCacheImage( None )

watcher = QFileSystemWatcher()
watcher.addPath( '/path/to/your/csv' )
watcher.fileChanged.connect( refreshLayer )
