However, it is inevitable that estimated ISA pixels contain anticipated other land covers (75% at maximum) and the observation of ISA from per-pixel analyses might not be straightforward.
Barelands that can be seen, including non-paved roads, are limited in the study area, thus they were not considered in this research. Biol. Conserv. 2008, 141, 1695–1703.

Grid Power functions similar to a point system; a generator will create a particular amount of GP, and a consumer will consume a particular amount of GP. If a consumer does not have enough GP to do its task, it will consume all the GP it can and do nothing.
