The paper shows how use of a structural-based approach improved capabilities for mapping and monitoring peatland condition with an improvement in accuracy from 71. 8% (without structural estimates) to 88. 0% when airborne LiDAR data (which had been spatially preprocessed using a technique called semivariogram analysis) were used.

Before I had this thing running, the measure of autocorrelation I was using in my accent model was to crank out a semivariogram for all the point pairs, add up the average value-distance for all the pairs on the “near” half of the variogram, add up the average for the “far” half, and compare the ratio of the “near” and “far” averages.

Quote: Three functions are used in geostatistics for describing the spatial or the temporal correlation of observations: these are the correlogram, the covariance and the semivariogram.

A statistical technique, semivariogram analysis, is used to isolate the variance resulting from the observational error from that resulting from the spatial variability in a dataset of the differences of paired SST reports.

The sampling variogram, unlike the semivariogram and the variogram, shows where a significant degree of spatial dependence in the sample space or sampling unit dissipates into randomness when the variance terms of a temporally or in-situ ordered set are plotted against the variance of the set and the lower limits of its 99% and 95% confidence ranges.

The semivariogram is directly related to the autocorrelation function (in fact it's that turned upside down) and computable from it.

Then, look up the semivariogram plot in Gavin's paper.
