K-NN without spatial input

I am a stats newbie. A geoscientist with only undergrad stats training. Doing “pure” prediction, no clustering. Have generated a predictive algorithm using several different techniques. Best regression coefficient was 0.85 with K-NN. I expected to have to input geospatial data along with the data for the predictors (6) and predicted.Can K-NN work like this or is it’s algorithm and predictions 100% spurious ?Thanks. See More

"Hi Randolph, you might want to explore kriging, as this is a popular tool for geoscientists. The book from Noel Cressie also addresses this topic and much more in the context of spatial statistics, see here. "
