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. |
Elevation ?Comment:A fundamental input is a Digital Elevation model (DEM). All algorithm calculations and valuations are produced at the resolution of this DEM – this ensures each service valuation delineates the landscape into elements consistent (identical) with the other service valuations so trade-offs can be meaningfully calculated. Applications to date suggest that a 5 m by 5 m DEM provides more than sufficient resolution for making decisions at the field scale. The extent to which utility decreases as resolution degrades is still to be established, but applications using 10 m by 10 m and 20 m by 20 m DEMS have to date provided generally appropriate information. A pre-processing tool is included with Polyscape to generate a hydrologically consistent DEM from a “standard” DEM. |
Habitats of interest ?Comment:Input is spatial coverage of each habitat of interest (map layer). |
Land use land cover |
Local slope ?Comment:This variable is used in Erosion/sediment delivery risk tool. |
Planform curvature ?Comment:This variable is used in Erosion/sediment delivery risk tool. |
Soil data ?Comment:Soil data is an optional input; this should always be included in regions where it is available (unless known to be of insufficient quality); if not available (as has been our experience in data sparse regions) a benchmark soil hydraulic capacity is input and spatial variations in this are estimated through applying multipliers to the land use through specification of hydraulic capacity multipliers. |
Soil type ?Comment:Class variable for determining soil carbon. |
Species of interest | Stream network |
Upslope drainage area ?Comment:This variable is used in Erosion/sediment delivery risk tool. |
Vegatation class ?Comment:Class variable used to determine carbon content of biomass. |
