As i calculate the SPEI1 using the 30 year data i get the value for the each month one value some of are in positive and negative also ? now how i say that this area is drought prone or not? and how to make a the map?
When the index values reach -1, the drought starts and the classification of drought classes in this index is the same as the classification of the Sh index presented by Edward and McKay (1997).
for the map; You should have the coordinates of the stations and calculate the index for each station separately, I think
