The Filter Panel

Overview​

The Filter Panel contains all filter controls defined in the Data Model's filter_fields configuration. Filters simultaneously narrow the features displayed on the map and update the Analysis Summary statistics.

Administrative Area Filters​

Geographic filters are rendered as searchable multi-select Combobox controls for columns matching administrative geography keywords. The Mozambique administrative hierarchy:

  • Province (Província / Região)
    • District (Distrito)
      • Administrative Post (Posto Administrativo)
        • Locality (Localidade)

Technology / Category Filters​

Checkbox filters are shown for string-valued columns. By default all values are selected (visible). Uncheck any value to hide features with that value. Values are colour-coded consistently with the map legend.

Numeric Range Filters​

Dual text-input range controls are shown for numeric columns. Enter a minimum and/or maximum to restrict the displayed features.

Common uses: Settlement Population, Investment Cost, Distance to Grid.

tip

Combine range filters with technology checkboxes — e.g. all mini-grid sites with population over 1,000 and investment cost under $500,000.

Applying and Clearing Filters​

Filter changes are staged. A visual indicator on each filter shows pending or active (changed from default) state.

  • Click Apply to commit all pending changes.
  • Click Reset to clear all filters to their defaults.

Applied filter state is encoded in the URL for bookmarking and sharing.
