Accessibility and Localisation

Geoman adds a polite aria-live region to the map container for selection changes and rejected operations. Set settings.announceActions: false to disable it.

settings.announcementResolver receives the announcement kind, contextual data, and defaultMessage. Return translated text, undefined to use the default English message, or an empty string to remain silent. A throwing resolver falls back to the default.

const gm = new Geoman(map, {
  settings: {
    announcementResolver: ({ defaultMessage }) => translate(defaultMessage),
    selectionMessageResolver: ({ defaultMessage }) => translate(defaultMessage),
  },
});

The selection resolver controls guidance on disabled controls that require a selection. A per-control requiresSelection.message takes precedence.

Keyboard actions are scoped to the map container and ignore form inputs. Arrow keys nudge the selected features by keyboard.nudgeStepPx (default 2); Shift multiplies the distance by ten. Enter completes a valid line/polygon draw. See Keyboard Shortcuts.

Live announcements are not a claim of complete keyboard accessibility: toolbar roving focus and keyboard vertex navigation remain future work.
