ADDED Requirements

Requirement: Map rendering with OSM tiles

The Planner and Journal SHALL render interactive maps using Leaflet with OpenStreetMap tiles as the default base layer.

Scenario: Default map view

  • WHEN a user opens the Planner or a route view in the Journal
  • THEN an interactive map is displayed with OpenStreetMap tiles centered on the route or a default location (Germany)

Requirement: Base layer switching

The map SHALL support switching between multiple base tile layers.

Scenario: Switch to OpenTopoMap

  • WHEN a user selects "OpenTopoMap" from the layer switcher
  • THEN the map tiles change to topographic tiles from OpenTopoMap

Scenario: Available base layers

  • WHEN a user opens the layer switcher
  • THEN the options include OpenStreetMap, OpenTopoMap, and CyclOSM

Requirement: Waypoint editing on map

The Planner map SHALL allow users to add, move, and delete waypoints by interacting with the map.

Scenario: Add waypoint by clicking

  • WHEN a user clicks on the map
  • THEN a new waypoint is added at the clicked location and synced via Yjs

Scenario: Move waypoint by dragging

  • WHEN a user drags an existing waypoint marker
  • THEN the waypoint coordinates update and sync via Yjs

Scenario: Delete waypoint

  • WHEN a user right-clicks a waypoint and selects "Delete"
  • THEN the waypoint is removed and the change syncs via Yjs

Requirement: Route visualization

The map SHALL display the computed route as a polyline on the map.

Scenario: Display route

  • WHEN BRouter returns a route GeoJSON
  • THEN the route is rendered as a colored polyline on the map

Scenario: Route updates on waypoint change

  • WHEN a waypoint is added, moved, or deleted
  • THEN the route polyline updates after BRouter recomputes the route

Requirement: Elevation profile display

The Planner SHALL display an elevation profile chart for the current route.

Scenario: Show elevation profile

  • WHEN a route is computed
  • THEN an elevation profile chart is displayed below the map showing distance vs elevation with total ascent/descent statistics

Requirement: Planner home page

The Planner home page SHALL provide a clear call-to-action to create a new planning session and a link back to the home page from within sessions.

Scenario: Home page CTA

  • WHEN a user visits the Planner home page
  • THEN a prominent "Start Planning" button is visible that links to /new

Scenario: Session home link

  • WHEN a user is in a planning session
  • THEN the header contains a link back to the Planner home page

Requirement: Map cursor rendering

Other participants' cursors on the map SHALL be clearly visible with proper styling.

Scenario: Cursor appearance

  • WHEN another participant moves their mouse on the map
  • THEN a colored pointer icon with their name tag appears at the cursor position

Scenario: Cursor does not obscure map controls

  • WHEN cursors are rendered
  • THEN they appear below map controls (zoom, layer switcher) in z-index
