Hi Rajni,
I could not understand your question clearly. If
you have data at the sampled points what is the use of any estimation
techniques? I think your aim is to estimate the value of variable of interest at
the unsampled locations by using sampled data. Do you mean this? If so, firstly,
you should know the spatial dependence structure of the variable over the study
area. Then, you can make estimations with kriging interpolation technique known
as BLUE. You can use inverse distance weighing (IDW) estimation technique which
is not objective. Without knowing whether data are spatially correlated and this
correlation is based on the distance between samples, the results obtained from
IDW technique are always questionable, and it is likely that they are senseless.
I hope this helps you.
Good luck and I wish you success.
