¹GRAIP_Lite uses the Standard International Units (SI) unit system commonly used in scientific and academic work. Since most users of this data are more likely to be using the U.S. Customary units (USC), and the thresholds for condition classes also use those units, we have done the appropriate unit conversions to provide a dataset using the USC units. It is important to note that, since we are using a unit baserate, that any sediment production and delivery values are index values and are not representative of actual sediment masses. If a baserate is known, however, they can be multiplied by that baserate in order to estimate actual sediment masses, but this baserate data is not widespread. Likewise, all slope stability values are index values and local knowledge is needed for interpretation.
