A dashboard with too many layers becomes difficult to use. Prioritization helps show the layers that support decisions first, while keeping detailed layers available for expert users.
1. Start from decisions
List what the dashboard must support: emergency response, project screening, land-use planning, or research analysis.
2. Group layers by purpose
Use groups such as hazard, exposure, vulnerability, capacity, and administrative reference.
3. Set default visible layers
Only show the most important layers at startup so the map opens quickly and clearly.
4. Add legends and metadata
Every layer should have a short description, source, year, and interpretation note.
5. Test with non-GIS users
If a planner cannot understand the default view in one minute, simplify the layout.
Keep the workflow simple: define the input, check the geometry or data source, validate the output, and then document the assumption inside the drawing, model, or dashboard.
