1.1 Model attributes via lynker-spatial

Some basin attributes may be rapidly acquired using the lynker-spatial data portal: As of hydrofabric v2.2, the following attributes include corresponding to the hydrofabric include:

"mode.bexp_soil_layers_stag.1", "mode.bexp_soil_layers_stag.2", "mode.bexp_soil_layers_stag.3", "mode.bexp_soil_layers_stag.4",
"mode.ISLTYP", "mode.IVGTYP", "geom_mean.dksat_soil_layers_stag.1" ,
 "geom_mean.dksat_soil_layers_stag.2", "geom_mean.dksat_soil_layers_stag.3", "geom_mean.dksat_soil_layers_stag.4",
"geom_mean.psisat_soil_layers_stag.1", "geom_mean.psisat_soil_layers_stag.2", "geom_mean.psisat_soil_layers_stag.3", 
"geom_mean.psisat_soil_layers_stag.4", "mean.cwpvt", "mean.mfsno", "mean.mp", "mean.refkdt", "mean.slope_1km",                    
"mean.smcmax_soil_layers_stag.1", "mean.smcmax_soil_layers_stag.2", "mean.smcmax_soil_layers_stag.3", "mean.smcmax_soil_layers_stag.4" ,    
"mean.smcwlt_soil_layers_stag.1", "mean.smcwlt_soil_layers_stag.2", "mean.smcwlt_soil_layers_stag.3", "mean.smcwlt_soil_layers_stag.4",     
"mean.vcmx25", "mean.Coeff", "mean.Zmax", "mode.Expon", "centroid_x", "centroid_y", "mean.impervious", "mean.elevation",
 "mean.slope", "circ_mean.aspect", "dist_4.twi"

Note that the "dist_4.twi" data column represents the quartile topographic wetness index. The RaFTS processing converts this json-formatted data column to the following data columns representing the approximate 25th, 50th, 75th, and 100th percentile twi values:

"twi_25pctl" "twi_50pctl" "twi_75pctl" "twi_100pctl"
