Method and provenance

Production method
A fixed 1 km buffer was constructed around river centrelines from Rasuwagadhi to the Narayani confluence, merging a partner upper-reach shapefile with OCHA's Humanitarian Programme Cycle Tools and Services corridor. OpenStreetMap and Overture layers were extracted for that planning area.
Provenance
Published by HOT through HDX. Component layers derive from OpenStreetMap and Overture Maps; the corridor geometry combines partner and OCHA sources.
Validation
Unclear
Uncertainty
OpenStreetMap coverage varies with mapping activity. Overture combines multiple upstream sources, including machine-generated content, and follows a different release cycle.
Limitations
The 1 km corridor is a planning boundary, not an observed or modelled inundation extent; presence inside it does not indicate exposure or damage.
