QRADE

QRADE (Risk Assessment for Damage and Exposure) is a QGIS Processing plugin for rockfall risk assessment based on the IMIRILAND methodology for landslides in mountainous areas. It combines kinetic-energy raster data with land-cover or exposed-element information to generate GIS outputs, reports, an interactive risk dashboard, and BIM-oriented deliverables.

Requirements

• QuickOSM is required for Auto land-cover generation from OpenStreetMap data.
• Auto land-cover mode requires internet access and availability of the Overpass API.
• Manual land-cover mode can be used offline with suitable local vector data containing a lowercase classification field.
• QPROTO is recommended for preparing the kinetic-energy raster, but QRADE can use suitable kinetic-energy raster outputs from other rockfall hazard-analysis tools.

Basic Workflow

1. Prepare a kinetic-energy raster in joules.
2. Choose Auto OSM or Manual land-cover input.
3. Choose the default risk-value table or a custom CSV.
4. Set the temporal probability mode.
5. Select an output folder.
6. Run QRADE and review the generated result folder.

Inputs

• Land Cover Source
• Extent
• Risk Assessment Values
• Area Type and Buildings Typology
• Kinetic Energy raster (J)
• Temporal Probability of Occurrence
• Output Folder and optional GIS layer outputs

Outputs

QRADE creates a timestamped QRADE_Result_TIMESTAMP/ folder with an organized structure:

• gis/: LandCover, Runout, and Risk Assessment GeoPackage layers.
• summary/: summary JSON and CSV files.
• bim/: BIM-ready CSV/JSON, IFC GUID mapping template, and BCF issues folder.
• reports/qa_qc/: QA/QC HTML, JSON, and CSV reports.
• reports/web_report/: Interactive Risk Dashboard, data, and assets.
• risk_tables/: copied custom risk-value table when Manual mode is used.
• qrade_output_manifest.json: manifest used by the QRADE Smart Assistant.

Smart Assistant

The QRADE Smart Assistant includes:

• Before running QRADE: Edit Risk Assessment Values.
• After running QRADE: Select QRADE Result Folder.
• Reports: Open Interactive Risk Dashboard and Open QA/QC Report.
• BIM Deliverables: Open BIM-ready CSV, Open IFC GUID Mapping Template, and Open BCF Issues Folder.

Risk Assessment Values

Default mode uses Input/classification_table.csv. Manual mode uses a user-selected custom CSV. The editor opens Templates/classification_table_manual.csv as the editable baseline and saves custom tables in the user QGIS settings directory. Do not edit the packaged Input/ or Templates/ CSV files directly.
