[Qgis-user] more from zonal statistics

[ambrish dhaka]

Dear Alexander,
I need your help!

I wish to find the highest and lowest point for each watershed (polygon). The points then should be exported to vector file.
Kindly,
 let me know how to get it from zonal statistics. I find that it 
provides half-way answer to what I need. It calculates the mean value
 and mentions in attribute table. It would be good if it gives the highest and the lowest 
value in attribute table as well. And, also provide for export of such 
points.

thanks! 
Ambrish Dhaka
