What if one is interested in the relationship between two areas, one which
is a subset of another, i.e one has a 100 km2 rectangular area, and the
area of interest is a 10 km2 area within that larger area, but also one is
interested in the relationship between the part and the whole, i.e. if land
cover changes in the part mimic larger trends in the whole. What methods are
there for statistically comparing the two?
One approach on this would be to divide the large area into 10 regions
of 10 km2 each, compute a variety of land cover change statistics for
all 10 regions (e.g. using the Map Comparison Kit, using landscape
metrics from Fragstats or using the land change module of Idrisi) and
finally use non-spatial statistics to find out if your special area
stands out significantly from the 9 others. I suppose this will only
work if the initial land cover patterns over the 10 regions are
sufficiently similar.
I am very curious to hear other ideas, so keep us posted.
Kind regards, Alex
