I know the definitions of the components of a semivariogram. However, I would want to know how they could be interpreted when applied to actual scenarios. For instance, I have two EVI (enhanced vegetation index) rasters computed from two different images (years 2000 and 2010). I calculated the semivariogram for each hoping I could compare them both, in terms of nugget effects, range, and sill values. First, can i do this? Second, how would i interpret a high range value for one and a low range for the other in terms of EVI? What about the rest of the properties: nugget effects and sill?
Image 1: nugget = 0.04,sill = 0.02, range = 6000, type = spherical, lag size = 750, no. of lags = 10, anisotropy = false
Image 2: nugget = 0.02,sill = 0.006, range = 1500, type = spherical, lag size = 250, no. of lags = 10, anisotropy = false
How would I "translate the variogram parameters into statements about the underlying EVI spatial patterns"?
