DEM reconditioning for hydrological applications
Project description
hydro-snap
Hydro-snap is a precise and efficient tool for seamlessly aligning digital elevation models (DEMs) with mapped stream networks, ensuring accurate hydrological flow paths with minimal terrain alteration.
Example of a DEM before (left) and after (right) alignment with HydroSnap. The DEM on the right has been aligned with the mapped stream network, ensuring accurate hydrological flow paths.
Installation
hydro-snap can be installed using pip:
pip install hydro-snap
Usage
Hydro-snap can be used to align a DEM with a mapped stream network using the following code:
from hydro_snap import recondition_dem
# Recondition the DEM
recondition_dem(DEM_PATH, STREAMS_SHP, OUTPUT_DIR, delta=DELTA, outlet_shp=OUTLET_SHP, catchment_shp=CATCHMENT_SHP,
breaches_shp=BREACHES_SHP)
