qgis to swmm

i'm trying to use your plugin with qgis 3.12.2 but there are any missing content in the downloaded file. i need a procedure to import in swmm 5.1 from a qgis' shape file. i hope you can send me a solution.
thanks

Flow Direction Raster format

The documentation in the input files mentions that we can generate flow direction from ArcMap and QGIS.

I am using QGIS and GRASS's r.fill.dir, the issue I am facing is that the coding of (agnps) mode is different to the one required in GIStoSWMM.

1 in agnps is north
1 required in GIStoSWMM is northeast

so,
Could you please share with us how you generated the raster?

as a temporary solution, I am writing a quick script to fix my coding. but curious about how to do it because it will simplify the workflow.

Thanks,
Faris

Non-roof landuse not mapped

Dear all,

thanks for this opensource.

When executing

./GisToSWMM5 raster_dem.asc raster_flowdir.asc raster_landuse.asc table_catchment_props.csv table_junctions.csv table_conduits.csv table_outfalls.csv table_header.csv table_evaporation.csv table_temperature.csv table_snowpacks.csv table_raingages.csv table_inflows.csv table_timeseries.csv table_pumps.csv table_curves.csv table_storage.csv table_dwf.csv table_patterns.csv table_losses.csv table_xsection.csv table_report.csv table_symbols.csv test/out 1

I receive

        64      0       0       0

This means that no non-roof landuse cells are mapped. The table_catchment_props.csv reads
