rios_preprocessor is meant as a platform-independent replacement for the ArcGIS python code that currently
produces the inputs for the main RIOS program.
rios_preprocessor produces rasters of:
- Downslope retention index
- Upslope source
- Riparian index
- Slope index
that are used as input for the following RIOS objectives:
- Erosion Control
- Nitrogen Retention
- Phosphorus
- Flood Mitigation
- Groundwater Recharge/Baseflow
Along the way, there are some additional tricks rios_preprocessor uses that may be useful in other contexts:
- rasterizes an input shapefile river network and matches it to a (raster) DEM/DTM
- identifies discontinuous river banks along a rasterized river
- identifies the end points of rasterized rivers
- numpy
- pandas
- geopandas
- fiona
- rasterio > 1.0
- shapely
- pygeoprocessing ~= 0.3.3
pip install rios_preprocessor
Questions about RIOS are picked up at the Natural Capital Project forums.
If you have any questions or comments about rios_preprocessor specifically, you can contact me through the Viridian Logic website.
- Reference stream input (vector) projection verified against raster projection. Vector reprojected if necessary.
- Minor PEP8 changes
- Began implementing routine to recover normalisation factors (flood objective only so far)
- Minor bug fixes
- Refactored stream rasterization to use geopandas
- Began introducing logging features (unfinished)
- Permitted a riparian zone of zero width
- Minor bug fixes
- Refactored and modularised code for increased usability
- Raster projection checks added
- Set deprecation warning for get_objectives_list()
- Minor bug fixes
- Fixed upslope source and riparian index getting affected by integer bug
