Hello Tim,
I have similar results with slope variable using 30m and 1km resolution, where
the contribution of slope was much lower using 30 m layer. In contrary, land
cover improved the prediction (as expected) when resolution increased.
It is quite logical that 1 km, 30 m and 1 m data give different results for
topographic variables. I.e. slope constructed over 1 km data shows how steep the
terrain is in general, slope from 30 m layer could detect differences over small
cliffs or hills and finally 1 m layer could detect large rocks as steep terrain.
Final choice depends on the species you study, but I guess 1 m resolution will
not give you very useful data regarding slope. We’ll see what the others think.
Cheers,
Miloš
