Demo: compute the accessibility of buildings to services
Download the workflow here, then import it into KNIME using File/Import KNIME Workflow.
This workflow demonstrates an advanced usage of the spatial features. We detect for every building if it can access a school.
Things to try
- Run the workflow
- Observe the results of the view, which displays in gray the area of accessibility of schools; in green the buildings which can access schools.
- Observe the outputs of the “Relate Geometries”
- Try to adapt the size of the buffer in the “Add column using ECQL expressions” node
