[Qgis-developer] Point sampling tool and python console

Hi all,

I am new to QGIS and to Python.

I would like to use the plugin point sampling tool in order to merge raster
datasets with my observations (a delimited text layer) and then save the
resulting shape file as a csv file. I know how to do it with the GUI:

Add Delimited Text Layer
Add Raster Layer
Point Sampling Tool
Join the layer
Save as .csv

As I have quite a lot of raster dataset to match with my observations (and
I am quite keen to learn Python), I would like to do it with a loop in the
Python console.

Thanks to this post <http://planet.qgis.org/snippets/2/>, I have:

crops="Wheat", "Maize","Barley", "Haricot Bean","Teff"

for i in crops: layer=QgsRasterLayer("C:/Program Files/LEAP/Images/Water

Any one knows what is the function for Point Sampling Tool, Join the layer
and save in Python?

More generally, how do we use plugins in the python console?

Thanks a lot,
