Hydroresolve is a workflow package built around refactoring, aggregating, and paramterizing/attributing hydrofabrics for ngen.
A primary input to the hydroresolve workflow is a mapping file that specifies the refactoring and aggregation parameters to apply to each unit of the NHD This file is stored in the ./data/ directory and is called ngen-hydrofabric-mapping.csv
| Process | Variable | Description |
|---|---|---|
| ID | RPU | Raster Processing Unit from the NHD |
| refactor | rf_min_da_km | This parameter represents the contributing area for a catchment.Anything under that size is treated as a non-dendritic area. e.g. there is no network logic applied. |
| refactor | rf_split_flines_meters | The maximum length flowpath desired in the output. |
| refactor | rf_collapse_flines_meters | The minimum length of inter-confluence flowpath desired in the output. |
| refactor | rf_collapse_flines_main_meters | The minimum length of between-confluence flowpaths. |
| aggregate | agg_keep | Topologically-aware geometry simplification. keep defines the proportion of points to retain (0-1; default 0.05) |
| aggregate | agg_ideal_area_k2 | The ideal catchment size in network |
| aggregate | agg_min_area_km2 | The minimum catchment size in network |
| aggregate | agg_min_length_km | The minimum flowpath length allowed in network |
