Tool Execution in QGIS

WbW-QGIS executes tools through the QGIS Processing framework.

Typical Execution Path

  1. Select a Whitebox algorithm in Processing Toolbox.
  2. Fill parameters in the algorithm dialog.
  3. Execute and monitor progress/messages.
  4. Load or inspect output artifacts.
  • Use explicit output paths for reproducibility.
  • Start with small representative datasets before full runs.
  • Validate intermediate outputs for CRS, schema, and metadata.
  • Keep task logs for long workflows and batch operations.

Output Handling

Whitebox tools may produce:

  • raster outputs,
  • vector outputs,
  • lidar outputs,
  • text/report sidecar artifacts.

Confirm output type and format before chaining into downstream steps.

Progress and Messaging

Execution status and warnings should be treated as part of result validation. If a tool completes with warnings, inspect outputs before continuing.
