Variable General Info
Aspect ?Comment:Users can also choose to consider aspect (varying according to hemisphere and with zero effect near the equator); this is used to upweight soil drainage and fertility valuations. For example, in the northern hemisphere south facing land catches light and tends to have better natural drainage and fertility characteristics than the “same” soil type in a non-north facing location. This variable is optional. |
